Choosing the wrong metal melting furnace is the fastest way to waste a weekend and a tank of propane. We spent weeks going through ten of the most-reviewed melting furnaces on the market, comparing burner output, element wattage, crucible material, and the complaints that only show up after your twentieth melt. The short version: the best metal melting furnaces for casting are the ones whose stated temperature ceiling actually clears the metal you plan to pour most often, and whose insulation is treated before the first firing.
This guide covers everything from 3kg electric benchtop units to 16kg dual-burner propane foundry kits. We break down how induction, electric resistance, and combustion heating behave, how to size a furnace for a real batch load, and which of the ten earns a place on a workbench. Every spec quoted here comes from the manufacturer listing and the owner reviews behind it.
One thing worth saying up front: almost none of these furnaces are single-use investments, and none of them are maintenance-free. Graphite crucibles wear out, ceramic fiber insulation needs a rigidizer coat before it will survive more than a few firings, and propane kits need airflow management. If you are outfitting a workshop, plan for a ventilation solution too — our notes on ventilation fans for casting workshops cover the extraction side that most first-time buyers overlook.

One note on reading that table: the capacity figure is the crucible rating, not the usable melt weight. A 6kg crucible realistically holds 4 to 5kg of usable charge with room remaining for expansion and for the flame to wrap the metal. Buyers who size a furnace on the printed number alone tend to regret the purchase on their first full pour.
What a Metal Melting Furnace Actually Does
A metal melting furnace is a controlled heating vessel that raises scrap or feedstock to its liquid state so you can pour it into a mold, ingot mold, or ladle. The metal sits in a crucible — usually graphite, sometimes ceramic — and heat reaches it by one of three routes: electrical resistance through a coil or element, electromagnetic induction through a coil that never touches the metal, or fuel combustion from propane burners.
For casting work, the furnace’s job is not just to reach a temperature. It has to get there repeatedly, hold it steadily enough to pour, and do so without eating its own insulation. That third requirement is where most cheap units disappoint, and it is the reason the kaowool warning shows up in nearly every review summary on this list.
Melting and smelting are different jobs. Smelting implies reducing an ore, usually with a flux, to separate metal from a bonded material. Melting takes metal you already have in metallic form and liquefies it. Every furnace in this guide melts; none of them smelts ore.
Induction, Electric Resistance, or Gas: Which Furnace Type Fits
Induction heating is the fastest and cleanest option here, and the Lee Precision melter is the only true induction unit in the group. An alternating current through a coil creates a magnetic field that heats the metal itself, which means almost no heat is lost to the surrounding air. The tradeoff is circuit demand: induction melters at real capacity want a dedicated high-amperage branch, not a shared extension cord.
Electric resistance furnaces use a heating element or coil inside an insulated chamber, which is what the five electric units here all do. They are quiet, clean, and need no fuel handling, but they heat a fixed volume of air and lining, so every wasted joule shows up on your meter. The 1350W and 1400W units in this list take 40 to 55 minutes for a full melt cycle, and that is the honest number to plan around.
Gas-fired furnaces heat a chamber with one or two propane burners. They are fast to recover, they tolerate larger crucibles, and they cost nothing but fuel to run — but they need a 30 PSI regulator, a ventilated space, and a working knowledge of air adjustment to avoid burning fuel without melting metal. The two-burner designs in this group heat the crucible from both sides and, in practice, give you a much more even melt than a single burner.
A practical decision framework: if you work indoors, on non-ferrous metals only, and want the least setup, go electric. If you melt aluminum in volume, recover scrap regularly, or want one furnace that can double as a forge, go propane. If you want speed with no flame and you can wire a proper circuit, go induction.
Matching a Furnace to Your Metal
Match the furnace to the metal by matching its temperature ceiling, because that is the single constraint that decides everything else. Aluminum and zinc alloys melt at the low end of the range and are forgiving of nearly any unit on this list. Copper, brass, and bronze sit substantially higher and will punish a furnace that cannot hold heat near the crucible walls. Iron and steel need temperatures far beyond anything in this roundup — no hobby-scale unit here is built for them.
For aluminum casting, the TOAUTO 6KG propane kit and the Nelyrho 6KG are the two strongest fits, both with burners that hit working heat fast and crucibles that accept a full charge without crowding. Reviewers report that the entry electric units handle aluminum well in practice, while the same units take a long time to bring a copper charge to temperature.
For copper alloys, brass, and bronze, prioritize chamber insulation thickness and burner count over raw BTU. The LSMIITTH 16KG carries 2 inch ceramic fiber and two burners, and the VEVOR 12KG reaches 2700°F in 6.5 to 8 minutes on dual burners. Both handle copper well; the smaller 6kg and 7kg kits will too, just with more patience between charges.
For precious metals, the rule is different: precision beats power. Gold and silver need controlled ramps rather than raw heat, which is what the PID-equipped units deliver. The Goodcrafter 2KG and the VEVOR gold furnace both reach their ceiling and hold it, and owner reports on sterling and 10k/14k work describe repeatable results. For cast iron, be honest with yourself — none of these units is the right tool, and a dedicated high-heat setup is a different category of purchase entirely.
How to Size a Furnace With a 30 Percent Buffer
Size a furnace by working out your real batch weight, then adding roughly 30 percent. If your typical pour is 4kg of aluminum, you want a crucible rated comfortably above 5kg so the metal is not sitting against the crucible wall with no room for the burner to work. Undersizing is the most common cause of the “it never quite gets hot enough” complaints in the reviews.
Scrap preparation matters as much as nameplate capacity. Oversized chunks heat far more slowly than a consistent charge of small pieces, so shred or chop your scrap before firing. A furnace that feels slow in January will feel slower still if you are feeding it whole door frames, and preheating a cold crucible before the main charge shortens the cycle noticeably.
Finally, count your realistic melt rhythm. One big 12kg pour every few weeks is a different purchase from a 3kg unit you fire twice a week. Buyers who move to a bigger furnace almost always say the same thing: the bottleneck was never the melt, it was the wait between melts.
1. Nelyrho 6KG Propane Melting Furnace Kit – Our Top Pick
Nelyrho 6KG Propane Melting Furnace Kit, 2500°F Stainless Steel Smelter
135000 BTU burner
2500F max temp
6KG graphite crucible
18.86 lb body
Pros
- Complete kit with crucible ingot mold tongs fire brick and gloves
- Heats up quickly and holds burner heat once adjusted
- Stainless shell holds up in repeated use
- Good capacity for aluminum recycling and small castings
Cons
- Crucible flakes graphite at the rim over many cycles
- Kaowool needs rigidizer or fibers can be breathed in
- Included gloves run thin during handling
This is the furnace we kept coming back to across every comparison we ran. The 135,000 BTU burner with a 30 PSI regulator reaches its 2500°F ceiling comfortably, and the 6KG graphite crucible has a built-in pouring spout that saves you from improvising a lip when you need to pour small ingots. At 18.86 pounds and 8.5 x 8.5 x 12.6 inches, it is compact enough for a one-car garage.
What makes it our pick is the accessory box. You get the crucible, an ingot mold, a pair of dual crucible tongs, fire brick, and gloves, so nothing else needs buying before the first firing. Owners report clean 1lb aluminum ingots and quick assembly, with 78 percent of ratings at five stars across 411 reviews.
Two things you should plan for. First, the graphite crucible is a consumable and it flakes at the rim as it ages, so keep a spare on hand rather than discovering the problem mid-pour. Second, the kaowool insulation should be treated with rigidizer before the first firing — untreated fibers are a real inhalation concern, and that single step is the difference between insulation that lasts and insulation that crumbles away.
The included ingot mold is small, producing a bar of roughly 7oz of aluminum, so plan to pour repeatedly rather than once. The thin gloves are the other common complaint; spend a few dollars on proper welding gloves before you handle a full crucible. The adjustment curve for burner air and propane is a genuine learning curve, and owners who spend a weekend tuning it report far better results than those who fire it wide open from the start.
Who the Nelyrho 6KG suits
This suits a hobby caster who wants a single furnace that handles aluminum, brass, copper, gold, and silver without swapping equipment. The 2500°F ceiling clears every non-ferrous metal you are realistically going to pour in a home shop, and the compact footprint means it does not eat a whole corner of the workshop.
It also suits anyone who wants a kit that works on the first firing. The burner, regulator, crucible, tongs, fire brick, and mold are all in the box, which removes the most common source of first-weekend frustration.
Who should skip it
Skip it if you plan to pour cast iron or steel, since 2500°F is nowhere near the temperatures those metals need. It is also the wrong choice for a full-time production shop, where a 6kg charge becomes a bottleneck within a few months.
If you are sensitive to loose refractory fiber or plan to cast indoors without a dedicated extraction setup, the electric units in this roundup are the calmer option. The Nelyrho is a garage tool that rewards good ventilation.
2. VEVOR 12KG Propane Melting Furnace Kit – Big Batch Capacity
VEVOR 12KG Propane Melting Furnace Kit Large Capacity Foundry Home, Blacksmithing Forge with Crucible & Tongs Kiln, Stainless Steel Smelter, for Metal Scrap Recycle, Gold Copper Silver Casting
Dual burners
2700F in 6.5-8 min
12kg graphite crucible
32 lb body
Pros
- Dual burners reach melting heat in 6.5 to 8 minutes
- 12kg crucible handles large copper silver and gold batches
- Non-welded integrated lid and stainless body feel durable
- Also works as a farrier forge
Cons
- Insulation crumbles faster than expected without rigidizer
- Instructions skip the rigidizer and refractory cement step
- Crucibles and fire bricks have arrived cracked on some units
The 12kg crucible is the headline here, and it is a real step up in throughput. The listing puts a single charge at up to 26kg of gold, 14kg of silver, 12kg of copper, or 3.6kg of aluminum, and the dual-burner layout with 1.2 inch insulation cotton reaches 2700°F in 6.5 to 8 minutes. Across 330 reviews it holds a 4.2 average with 64 percent five stars.
The second function is what separates it from the other propane kits here. It doubles as a farrier forge, so once you are finished melting you can start forging without moving to another piece of equipment. For a blacksmith who also casts, that dual use changes the economics of the purchase.
The weak point is insulation life, and it is the same story as the other kits in this range. The kaowool burns down faster than most buyers expect unless it is sealed with rigidizer and refractory cement, and the manual does not clearly explain that step. Owners who follow the process report dramatically longer-lasting linings; owners who skip it report the lining crumbling within a handful of firings.
Check the box on arrival. Fire bricks and the large crucible have shown up cracked on some examples, and the included tongs are loose-fitting for a 12kg crucible, which is not what you want when lifting several kilos of molten metal. The tack-welded construction and undeburred edges are also visible if you look closely. None of that is dangerous, but it tells you this is a utility tool rather than a finished piece of equipment.
Who the VEVOR 12KG suits
This suits anyone melting more than a few kilos at a time, particularly copper, silver, or gold scrap where batch size drives the economics. If you melt once a month for hobby jewelry, it is far more furnace than you need. If you melt weekly for resale or restoration work, the capacity earns its keep quickly.
It also suits dual-purpose buyers. The forge function means a single unit covers both casting and forging, which removes a second large piece of equipment from the shopping list.
Who should skip it
Skip it for a small workshop where 32 pounds of furnace and a 16.54 x 15.55 x 15.35 inch package is a lot of bench to give up. The 4.2 average also reflects a wider spread of quality than the top pick, with 8 percent one-star ratings driven mostly by damaged parts on arrival.
Buyers who want a finished-looking product with tight tolerances should look at an electric unit instead. This one rewards a hands-on owner who is willing to check hardware and replace consumables.
3. CANALHOUT 7KG Propane Melting Furnace Kit – Complete Kit
CANALHOUT 7KG/15lbs Propane Melting Furnace Kit w/ 2 Tongs & Crucible
135000 BTU burner
1400C max temp
7kg copper capacity
24 lb pentagonal body
Pros
- Arrives complete and ready to light with burner hose tongs and crucible
- Large lid holds heat and stops flame escape
- Separate lifting and pouring tongs
- Melts gold silver aluminum copper and glass
Cons
- 7kg capacity trails some rivals at a similar tier
- Included gloves are light protection
- Insulation still needs a rigidizer treatment for long life
The CANALHOUT is the kit we would hand to someone who has never lit a furnace before. The box contains the burner, hose with regulator, lifting and pouring tongs, crucible, torch, fire brick, PTFE tape, thumb screw, gloves, and a manual, and owners consistently describe lighting it for the first time as uncomplicated. It holds 4.4 across 308 reviews with 74 percent five stars.
Its 135,000 BTU burner with a 30 PSI regulator heats to 1400°C, and the 1.2 inch ceramic fiber insulation with custom nozzles holds that heat. The upgraded large lid is the detail that shows up most often in positive reviews, because it keeps the flame contained and cuts the fuel needed to hold temperature.
Two separate tongs is a small thing that makes a real difference. Having one tool for lifting and another for pouring means you are not trying to reposition a full 7kg crucible with the same grip you used to pick it up, which is where a lot of hobby casting injuries actually start.
The 1400°C ceiling handles gold, silver, aluminum, copper, and glass, which makes it one of the more versatile furnaces in the roundup. The tradeoff is that 7kg is a little smaller than some competitors, and the pentagonal chamber is less accommodating for a large crucible than a cylindrical body. Most buyers end up adding their own molds, spare crucibles, and better gloves anyway.
Who the CANALHOUT 7KG suits
This suits first-time foundry owners who want everything in one box. If you have never assembled a burner, sealed a hose, or balanced a regulator, the completeness of this kit removes most of the learning curve before it starts.
It also suits anyone working across several non-ferrous metals, since 1400°C clears aluminum, copper, brass, gold, and silver in the same chamber. The dual-tong setup suits a shop where safe handling matters more than raw speed.
Who should skip it
Skip it if your batch size regularly exceeds 6kg of usable charge, because the nameplate figure leaves little headroom. It is also the wrong fit for a cast iron or steel plan — nothing in this roundup reaches those temperatures.
Owners who need a furnace that also forges should look at the VEVOR 12kg instead. The pentagonal chamber and the small included accessories are entry-level, so budget for replacements before your second season of heavy use.
4. Lee Precision Electric Metal Melter Pro 4 – No Open Flame
Lee Precision Electric Metal Melter Pro 4 – 20 LB
20 lb capacity
Electric induction
Compact benchtop
Metal and plastic build
Pros
- Compact footprint fits a reloading or hobby bench
- Melts a full 20 lb load in one cycle
- No propane regulators or open flame to manage
- Few moving parts and simple operation
Cons
- Induction heating suits non-ferrous metals only
- Needs a dedicated high-amperage circuit for full capacity
- Fewer accessories bundled than the propane kits
The Lee Precision melter is the odd one out in this roundup and that is exactly why it made the list. It is an induction unit, which means heat goes straight into the metal with no open flame anywhere near your shop, no propane regulator to adjust, and no combustion products to vent. It holds 4.6 across 282 reviews with 82 percent five stars, the second-highest satisfaction level in the group.
The 20 lb capacity is genuinely useful for small-scale production. Reloaders use it for bullet casting, and small-scale hobby casters use it for ingots and short runs. The metal and plastic construction keeps the weight manageable, and the simple single-purpose design means there is very little that can go wrong mechanically.
There are two real constraints. The first is that induction heating is a non-ferrous technique — steel and iron will not couple with the field the way aluminum, copper, or lead do, so this is not the furnace for ferrous work. The second is electrical: to run a full 20 lb charge you want a dedicated high-amperage circuit rather than a shared household outlet.
Fewer accessories are bundled than the propane kits, so plan on sourcing tongs and molds separately. In exchange you get a furnace that can sit on a bench indoors, starts with a switch, and produces no ash, no flame licking out of the lid, and no fuel to store.
Who the Lee Precision melter suits
This suits reloaders, small jewelry operations, and anyone melting non-ferrous metal in a room that does not have outdoor ventilation. It is also the easiest furnace here to learn on, because there is no burner to tune and no propane lock to work out.
If you already have a solid high-amperage circuit and you want to stop storing fuel cylinders, the convenience difference is large. The 20 lb single-cycle charge is the largest useful load in a compact form factor among the electric units here.
Who should skip it
Skip it if you plan to work with iron or steel, or if you need to reach copper temperatures repeatedly in a short session. It is also a poor fit for a workshop that can only offer a lightly loaded general-purpose outlet.
Buyers who want a furnace that also serves as a forge should look at a propane model. The Lee Precision does one job extremely well and does not pretend to do several.
5. TOAUTO 1+3KG Gold Melting Furnace – Jewelry Workhorse
TOAUTO Gold Melting Furnace 1+3 KG 1400W 2100℉
1400W at 110V
1100C max temp
1kg and 3kg crucibles
7.5 kg unit
Pros
- PID control with LED display gives repeatable settings
- Two crucible sizes plus a 5-in-1 ingot mold
- No fuel tanks or open flame
- UL listed with a one-year warranty
Cons
- Struggles to reach the 1100C copper melting point
- Included ingot mold pours very small ingots
- One report of display and housing failure after a single use
The TOAUTO TGF3000 is built around precision rather than power. A 1400W element at 110V drives PID digital temperature control with an LED display, so you can set a target and repeat the same melt tomorrow. It comes with 1kg and 3kg graphite crucibles plus a 5-in-1 graphite ingot mold, which is a genuinely useful accessory set for anyone working sterling, gold, or small castings.
At 10 x 11.5 x 12 inches and 7.5 kg it is a substantial but manageable bench unit, and it is UL Standard listed in the US with a one-year warranty and lifetime technical support. It holds 4.1 across 281 reviews with 68 percent five stars, and customer service is singled out repeatedly as a strength, with free probe and unit replacements.
The honest limitation is the temperature ceiling. The unit is rated to 1100°C, which is fine for gold, sterling silver, and aluminum, and marginal for copper. Owners report that reaching the copper melting point can take well over an hour, and the naming convention on the listing implies a higher figure than the element actually delivers. Plan around the listed ceiling, not the product name.
The included ingot mold is small, and one review reports the front display and housing failing after a single use, so inspect the unit carefully on arrival. The body is heavy and stable but does occupy meaningful bench space for what it pours.
Who the TOAUTO TGF3000 suits
This suits a jeweler or small caster working primarily in gold, sterling, and aluminum who wants repeatable temperature rather than maximum throughput. The PID readout is the reason: when every pour has to match the last one, a set-and-hold controller removes a whole category of guesswork.
It also suits anyone melting indoors who wants no propane storage and no open flame. The 1kg and 3kg crucible pairing lets you run small jewelry batches or a larger pour from the same machine, and the UL listing matters in a home studio.
Who should skip it
Skip it if copper and copper alloys are your main medium, because the 1100°C ceiling will make every melt a long wait. It is also the wrong tool for iron or steel, and for anyone who needs more than about 2kg of usable charge per cycle.
Owners who want a larger electric capacity should look at the VEVOR 3kg unit, which reaches 1150°C. If copper work is central to your casting, the propane kits in this roundup are a better match.
6. TOAUTO 6KG Propane Kit – Fast Aluminum Melts
TOAUTO 6KG Propane Melting Furnace Kit TMF6000B-V3 Propane Foundry Home Kiln Casting Tool for Smelting Casting Gold Silver Copper Scrap Metal Recycle Aluminum
250000 BTU single burner
1300C max temp
6KG crucible
15.4 lb body
Pros
- 250000 BTU burner melts aluminum in roughly 10 minutes
- 1.2 inch ceramic cotton holds heat better than thinner rivals
- Powder-coated body resists wear
- Detachable no-hinge lid speeds crucible access
Cons
- Single burner heats the chamber less evenly than dual-burner designs
- Insulation still needs sealing after repeated melts
- Included gloves and tongs are entry-level
The TMF6000B-V3 is the aluminum specialist of this group. Its 250,000 BTU single burner with an adjustable 30 PSI regulator melts aluminum in roughly 10 minutes, and the 1.2 inch (30mm) ceramic cotton insulation rated for 2000°F and above holds that heat better than the thinner linings on entry-level furnaces. The V3 revision also adds an enlarged rocket stove design, an improved burner inlet valve, and a powder-coated body.
For anyone recycling aluminum cans, window frames, or castings, the speed-to-charge ratio here is hard to beat. The detachable no-hinge lid makes crucible access faster than a hinged design, and the kit includes the furnace, burner set, 6KG crucible, 113ML graphite ingot mold, regulator, tongs, gloves, and manual.
Its rating is 4.0 across 204 reviews, the widest spread in the roundup, with 15 percent one-star feedback. Most of the lower scores trace to a single design point: one burner cannot heat a chamber as evenly as two, so the top of the chamber runs cooler and you need to rotate your crucible position during the melt to even out the result.
The insulation still needs sealing or replacing after repeated cycles, and the included gloves and tongs are entry-level. The 113ML ingot mold is small enough that pouring a full crucible takes several pours, so factor that into your cycle time.
Who the TOAUTO 6KG propane kit suits
This suits an aluminum recycler or a caster who works primarily in low-melting-point metals. Ten-minute aluminum melts and thick insulation mean more charges per propane hour than the smaller kits in this roundup.
It also suits a buyer who wants a straightforward single-burner design with nothing to configure. There is one regulator to set and one lid to remove, which keeps the learning curve short for someone comfortable with propane tools.
Who should skip it
Skip it if you need precise temperature control for precious metals, since there is no PID controller here — you are reading flame color and adjusting air. It is also the wrong choice for anyone who casts copper regularly, because the single-burner unevenness shows up more at higher temperatures.
Buyers who want even heating across a large crucible should compare the dual-burner propane models. The 15 percent one-star rate here is worth weighing against that.
7. VEVOR 3kg Electric Melting Furnace – Compact and Simple
VEVOR 3kg Electric Melting Furnace 1350W Electric Metal Smelter Foundry
1350W element
1150C max temp
3kg ceramic crucible
23.4 lb unit
Pros
- Ceramic crucible outlasts a graphite one
- Digital control panel is simple for a first-time user
- 1350W element reaches melting heat evenly for small batches
- Holds steady temperature across repeated pours
Cons
- Listing does not clarify whether ingot molds or refractory coating are included
- Only a 3kg crucible size limits throughput
- Some buyers report wobbly hardware on arrival
The VEVOR KD-1101 is a 1350W electric furnace that reaches 1150°C (2102°F) with smart digital temperature control. The 3kg chamber uses a ceramic crucible with a protective mesh design, and reviewers consistently single out that ceramic as the reason it performs better than similar-priced graphite units over time. A ceramic crucible outlasts graphite, which changes the long-run consumable math in its favor.
At 10.63 x 9.84 x 14.96 inches and 23.4 pounds it is a compact unit for its output, and the control panel is straightforward enough that a first-time user can set a target temperature without reading a manual twice. It holds 4.0 across 184 reviews with 54 percent five stars, the lowest five-star share in the roundup.
One thing to resolve before you buy: the listing does not state whether ingot molds or refractory coating materials are included. Ask the seller, and plan on sourcing molds separately. Some buyers also report inconsistent hardware quality between production runs, with wobbly fittings out of the box, so inspect the chassis on arrival and tighten anything loose before the first firing.
Who the VEVOR 3kg electric unit suits
This suits a hobby caster working in jewelry-scale, badge, or small art castings who wants electric convenience in a small footprint. The 3kg ceramic crucible handles small precious-metal batches cleanly without fuel handling or a ventilation upgrade.
It also suits anyone who values consumable life over raw capacity. When a ceramic crucible outlasts graphite, the per-melt cost drops even though each crucible costs more to buy.
Who should skip it
Skip it if you need to pour more than about 2kg of usable charge or run production batches, because a single 3kg crucible sets the ceiling. It is not a fit for cast iron or steel.
The 54 percent five-star share is the widest in the group, and part of that comes from uncertainty about what is in the box. Buyers who want a more predictable package should look at a model with a clearly itemized accessory list.
8. Goodcrafter 2KG Digital Melting Furnace – Sterling and Gold
2KG Gold Melting Furnace 1150℃ /2102 ℉ Automatic Digital Melting Furnace Machine with Graphite Crucible for Precious Metals Gold Silver Jewelry,1400W
1400W at 110V
1100C max temp
2kg graphite crucible
Melts in 40-48 min
Pros
- Heats up quickly and holds temperature for sterling and gold
- Adjustable set temperature stops the ramp at the pour point
- Tongs fit the groove around the crucible head
- Warranty support replaces crucibles probes and units
Cons
- 2kg crucible is small for larger pours
- Supplied crucible may only survive a couple of uses
- Some units report internal wiring failures within months
The Goodcrafter GC-SG-RRL-2KG has been on the market for years, and that longevity shows in the owner reports. It runs 1400W at 110V, holds a 2kg graphite crucible, and reaches 1100°C (2000°F), melting metals completely in 40 to 48 minutes. Long-term owners describe it as a dependable jeweler’s workhorse for sterling and 10k/14k gold, and 70 percent of its 145 reviews are five stars.
The PID module and digital control are the reason it earns its place for copper alloy work at this capacity. Being able to stop the ramp at a set temperature rather than guessing means you can bring a bronze or brass charge to temperature without overshooting into a burn range where the alloy loses its intended properties.
Two recurring problems are worth planning around. The supplied graphite crucible can only survive a couple of uses before needing replacement, and one owner reports a cracked crucible during a copper melt that damaged the temperature probe and heating element — a reminder to inspect crucibles before every fire and replace them on a schedule rather than when they look thin.
Some owners also report internal wiring burning out within months. The 12-month warranty with a promised support response within 24 hours has repeatedly rescued those buyers with free replacements, and customer service is credited with replacing crucibles, probes, and entire units. Molten metal still needs torch-heating at the pour point to avoid premature solidification, which is normal for a unit this size.
Who the Goodcrafter 2KG suits
This suits a working jeweler or a small caster who melts sterling, gold, and copper in jewelry-scale volumes and values temperature repeatability. The long production history and responsive warranty support reduce the risk on a purchase that involves consumables and electrical parts.
It also suits anyone who needs precise ramp control at a lower price point than a full jeweler’s induction unit. The 20.5 pound body and 110V supply make it an indoor machine with no circuit upgrades required.
Who should skip it
Skip it if you need pours larger than about 1.5kg of usable charge, because the 2kg crucible is the hard limit. It is also the wrong choice for iron or steel, and for anyone who cannot tolerate a consumable replacement cycle.
The wiring failure reports are the main reason to buy only with the warranty in place. If a larger ceramic crucible would serve you better, the VEVOR gold furnace model offers 1kg and 3kg crucibles in one package.
9. VEVOR Gold Melting Furnace 1350W – Easiest Controls
VEVOR Gold Melting Furnace, 1350W, 2102 ℉, PID Digital Electric Melting Furnace with 1 kg and 3 kg Ceramic Crucibles, Insulated Gloves, Crucible Tongs and Tray, for Gold, Silver, Aluminum, Copper
1350W element
1150C max temp
1kg and 3kg crucibles
21.2 lb unit
Pros
- PID digital control is straightforward for a first-time user
- Two ceramic crucible sizes cover small and large pours
- Includes insulated gloves tongs crucible tray and manual
- Mesh face shield and non-slip pads help during handling
Cons
- Limited review history for long-term reliability
- 40-55 minute warm-up per cycle
- Needs a ventilated work area
- Ceramic crucibles are still consumables
This is the most beginner-friendly electric furnace in the roundup. A 1350W element reaches 1150°C (2100°F) through a PID digital system with a 4-button panel and LED display, so setting a temperature is a matter of pressing up, pressing down, and waiting. It melts metals below 1150°C in 40 to 55 minutes and holds a 4.3 average across 115 reviews with 67 percent five stars.
The accessory package is unusually complete for this category: 1kg and 3kg ceramic crucibles, insulated gloves, tongs, a 5-hole crucible tray, power cord, and manual. A mesh face shield reduces heat exposure during pours, and the wide handles plus non-slip pads keep the unit stable while you are working around it.
The honest caveat is the review history. At 115 reviews this is the newest listing in the group, so the long-term track record simply has not accumulated yet. The early reception is solid, but you are buying on a shorter evidence base than the top pick, which has four times the review volume.
Plan the cycle time before you commit. A 40 to 55 minute warm-up per cycle is a real constraint if you only cast occasionally, and you still need a ventilated work area for comfort and safety even though there is no open flame. Ceramic crucibles outlast graphite but are still consumables, so keep spares.
Who the VEVOR 1350W gold furnace suits
This suits a first-time electric melter who wants clear controls and a full accessory set in one package. The 4-button PID panel and LED readout remove the interpretation step that makes cheap controllers frustrating, and the mesh face shield is a thoughtful touch for a machine that is meant to be run indoors.
It also suits a jeweler who alternates between very small batches and larger pours, since the 1kg and 3kg ceramic crucibles cover both without changing machines. Gold, silver, lead, copper, bronze, aluminum, and scrap refining are all within its stated range.
Who should skip it
Skip it if repeatability over years matters more than features, because the limited review history gives you less to go on. It is also the wrong choice for iron or steel, and for anyone who wants a fast melt rather than a controlled one.
Buyers who want a proven record should look at the Goodcrafter, which has been in production for years with a comparable temperature ceiling. If you plan to melt copper regularly, verify the ceiling against your alloy before committing.
10. LSMIITTH 16KG Dual Burner Propane Furnace – Thickest Insulation
LSMIITTH 16KG Propane Melting Furnace for Aluminum, Gold, Silver, Copper – Dual Burner 200,000 BTU High Efficiency Foundry Kit with 16KG & 6KG Crucibles, Metal Clip Tongs for Casting Jewelry & DIY
Two 100000 BTU burners
2 inch ceramic fiber
16kg and 6kg crucibles
33 lb body
Pros
- Dual burners heat both sides of the crucible evenly at 3-4 PSI
- 2 inch insulation cuts fuel use and warms up quickly
- Two crucible sizes for large batches or precise small melts
- Adjustable air chokes and brass bell heads aid maintenance
Cons
- Supplied tongs are too small for the 16kg crucible
- Supplied crucibles can chip and gloves have incomplete stitching
- Aluminum lid handle and hardware can soften near the chamber
- Burner nozzles are cast iron and wear away
The LSMIITTH F15KB-A is the biggest furnace here and the most insulated. Two 100,000 BTU forge burners give 200,000 BTU combined, and the 2 inch (50mm) premium ceramic fiber inside a 1.5mm steel shell is specified to deliver up to 50 percent faster melting and roughly 20 percent lower propane use. The chamber is 8 inches in diameter by 10 inches deep, and it holds a 4.1 average across 116 reviews with 59 percent five stars.
Two crucibles ship with it: a 16kg graphite crucible rated at up to roughly 30kg of gold, 18kg of silver, 16kg of copper, or 5kg of aluminum, and a 6kg crucible for smaller melts. Owners consistently credit the dual-flame layout with even melting of copper, brass, and aluminum, and the adjustable air chokes on each burner plus brass bell heads make maintenance straightforward.
The supplied accessories are the weak link, and this comes up in nearly every critical review. The tongs are too small for the 16kg crucible, and several owners lifted with them anyway and damaged the tool. The crucibles can chip and break, the gloves have incomplete stitching, and the lid handle plus some hardware are aluminum, which softens near the chamber. Replace all three accessories before your first heavy pour rather than after.
Burner nozzles are cast iron and burn away over time, so keep a spare on hand. It is rated for metals below 2372°F (1300°C) and is explicitly not suitable for steel or iron, which matters if your plans change. Seller support is credited with quick responses to damage on arrival, and a broken igniter shows up on some packages.
Who the LSMIITTH 16KG suits
This suits a serious home foundry or small production shop that melts copper, brass, or aluminum in real volume and wants even heat across a large crucible. The 2 inch insulation and dual burners deliver the lowest fuel use per melt in this roundup, which compounds quickly across repeat cycles.
It also suits buyers who want two crucible sizes from one machine, so small precise melts and large batches use the same furnace. The 33 pound body and 12 x 12 x 15 inch footprint are manageable for a dedicated corner of a workshop.
Who should skip it
Skip it if your budget is tight and you are still deciding whether you will cast at all — the accessory replacements alone are a real cost. It is also the wrong choice for indoor-only use without a dedicated ventilation plan, and for iron or steel of any kind.
Buyers who want big capacity with a more complete factory accessory set should compare the VEVOR 12kg. For most hobbyists, a 6kg or 7kg kit covers the same work at a fraction of the commitment.
Buying Guide: What to Check Before You Commit
Check the temperature ceiling against your metal first, because it eliminates options faster than any other specification. Aluminum and zinc melt at the low end and work with nearly every unit here. Copper, brass, and bronze need a furnace that can hold high heat around the crucible walls, which points toward the propane kits with 1.2 to 2 inch insulation. Iron and steel fall outside what any of these ten furnaces can do.
Second, check usable charge against the nameplate. A 6kg crucible is a 6kg crucible, but you should plan on 4 to 5kg of metal with headroom for expansion and burner clearance. If your typical pour exceeds that, move up a size rather than crowding the crucible.
Third, check what is included. The propane kits in this roundup vary widely: the Nelyrho and CANALHOUT arrive with genuinely complete kits, while the LSMIITTH ships with undersized tongs and gloves. Assume you will replace gloves and tongs on any of them, and add a spare graphite crucible or two to your first order.
Fourth, check the insulation instructions. Every kaowool furnace here benefits from a rigidizer or refractory cement treatment before its first firing, and several manuals skip that step. Plan to spend an afternoon sealing the lining before you load metal, because untreated fiber both breaks down faster and puts loose particles into the air you breathe. Our notes on angle grinders for metal cutting cover the shaping work you will want to do on scrap before firing.
Finally, think about circuit and ventilation before delivery day. Electric units at 1350W and 1400W want a clean outlet on a load that can handle the draw, and induction units want more. Propane units need an outdoor-adjacent space or a real extraction plan, plus a place to store cylinders safely. For non-metal work in the same shop, our silicone mold kits for prop casting guide covers the mold side of the process.
Safety, PPE, and Installation Requirements
The essentials are face shield, leather gauntlet gloves rated for handling hot metal, safety glasses, flame-resistant clothing, and a clear working area with no combustibles within reach. Molten metal does not behave like water — a splash of aluminum at casting temperature causes severe burns and will ignite clothing — so the shield and the gloves are not optional accessories.
For propane furnaces, check your hose and regulator connections with soapy water before the first lighting and re-check periodically. Never leave an unattended propane furnace running, keep a fire extinguisher rated for flammable liquid nearby, and make sure the lid is seated so the flame stays inside the chamber. The large lids on the CANALHOUT and Nelyrho exist for exactly this reason.
For electric furnaces, the risks are different but not smaller. Ceramic fiber insulation produces fibers that should not be inhaled, so work in a ventilated area and avoid disturbing the lining when it is hot. Keep water away from the unit, and let the chamber cool before reaching in — the exterior runs far hotter than the room temperature suggests.
One last practical note: have a plan for a spill. When a full crucible tips, you need somewhere safe to dump several kilos of molten metal before it solidifies, and you need a plan that does not involve people. Practise the pour with a half charge the first time.
Maintenance, Energy Use, and Expected Service Life
Every furnace here has a consumable that sets its real service life, and it is almost never the burner or the element. Graphite crucibles wear out fastest; the VEVOR listing states an average of 2 to 3 uses for its 12kg crucible, and owners of the Goodcrafter report a similar short life on the supplied graphite pot. Ceramic crucibles outlast graphite, which is the main reason to accept the higher upfront cost on the electric units.
Insulation is the second consumable. Untreated kaowool breaks down within a handful of fires, and a rigidizer or refractory cement treatment is what separates a lining that lasts from one that crumbles. Refractory failure is also the most common cause of a slow, uneven melt, so treat it as maintenance rather than an upgrade.
On energy use, the honest comparison is propane volume against cycle time for gas, and wattage against kilos melted for electric. The LSMIITTH is specified at up to 50 percent faster melting and roughly 20 percent lower propane use than a thinner-lined equivalent, and the electric units here draw 1350W to 1400W for a 40 to 55 minute cycle. If you melt rarely, wattage matters less than your time; if you melt weekly, both fuel draw and cycle length compound.
Plan on replacement parts being part of the purchase rather than an exception. Keep spare graphite crucibles, a spare igniter for propane units, and a spare heat probe for electric units. The brands with the strongest support in the reviews — TOAUTO and Goodcrafter in particular — are the ones that have replaced probes, crucibles, and whole units under warranty.
Frequently Asked Questions
What is a good mini furnace for melting metal?
For jewelry-scale and small hobby pours, the VEVOR 3kg electric unit and the VEVOR 1350W gold furnace are the most practical mini options. Both run on standard 110V power, reach about 1150°C, and use ceramic crucibles that outlast graphite. The Goodcrafter 2KG is a similar size with a longer production history. For scrap-scale work in a garage, the Nelyrho 6KG propane kit reaches far higher temperatures in a compact body.
Which electric furnace is best for melting metal?
It depends on the metal. For aluminum and low-melting-point alloys, the TOAUTO 1+3KG is a strong pick because its PID controller gives repeatable setpoints. For gold and sterling, the VEVOR 1350W model and the Goodcrafter 2KG both deliver controlled ramps and responsive warranty support. The Lee Precision melter wins on speed and capacity if your circuit can handle it. None of these electric units reaches iron or steel temperatures.
What furnace do I need for aluminum casting?
For most home aluminum casting, any furnace in this roundup will physically do it, but the best fits are the fast propane kits: the TOAUTO 6KG with its 250,000 BTU burner melts aluminum in roughly 10 minutes, and the Nelyrho 6KG adds a 2500°F ceiling for mixed-metal work. If you want to cast indoors without fuel, the electric units handle aluminum fine, just more slowly.
Which furnace is used for melting cast iron?
None of the furnaces in this roundup. Cast iron needs temperatures far above the 1150°C to 1400°C ceilings these units reach. Hobby-scale cast iron work calls for a dedicated high-heat coke or induction setup, not a crucible furnace from this category. Set cast iron aside and choose based on aluminum, copper alloys, or precious metals instead.
Can you melt copper in a propane furnace?
Yes, and the propane kits here are the right tool for it. The LSMIITTH 16KG and VEVOR 12KG both handle 12kg to 16kg crucible charges of copper with dual burners and thick insulation. Smaller kits such as the Nelyrho 6KG and CANALHOUT 7KG reach copper temperatures too, with a longer wait. Electric units are the weaker choice: the 1100°C ceilings on several of them make copper melts take well over an hour.
Conclusion
After working through all ten, the Nelyrho 6KG propane kit is our pick for the best metal melting furnaces for casting in 2026. It pairs a 2500°F ceiling with the most complete accessory box we found, holds a 4.6 average across 411 reviews, and handles every non-ferrous metal a home shop realistically pours. If you want big batches and a forge function, the VEVOR 12kg is the alternative; if you want to stay away from propane entirely, the Lee Precision melter gives you a 20 lb induction charge from a bench-sized unit.
Whichever one you pick, treat the first weekend as preparation rather than casting. Seal the insulation, source spare crucibles and real gloves, check the electrical load, and practise the pour with a half charge. That habit is worth more than any specification on the box.
