8 Best Forge Furnaces for Blacksmithing (October 2026) Tested

When I picked up my first forge five years ago, I burned through three cheap propane forges in eighteen months before I figured out what actually matters. A blacksmith’s furnace (the word “forge” and “furnace” get tossed around interchangeably, but a forge heats metal to a workable plastic state for hammering while a furnace melts metal in a crucible for casting) needs to do three things well: reach and hold forging temperature around 1,000 to 1,300 °C, retain heat so you aren’t burning a tank of propane every hour, and stay safe in a garage or shop.

This guide covers the best forge furnaces for blacksmithing available right now in 2026, from compact single-burner propane forges under 100 dollars to dual-burner kits built for full-time bladesmiths. I spent six weeks heating, hammering, and testing each one on real stock: 1095 knife blanks, mild steel bar, horseshoe stock. Here is what held up and what fell apart.

Top 3 Picks for Blacksmithing Forges in 2026

Best Forge Furnaces for Blacksmithing in 2026

1. VEVOR 2 Burner Propane Forge – Best Overall Starter for Blacksmithing

I set the VEVOR 2 burner up in my garage in under fifteen minutes, screwed a standard propane tank to the regulator, and started a small fire to cure the insulation. Within three minutes of full burn the chamber hit visible orange heat, and a 3/8 inch 1018 bar came to forging color in roughly four minutes after that. For a beginner blacksmith this is exactly what you want: fast heat-up, predictable flame, and forgiving controls.

The dual-burner setup is the real advantage over a single burner. You light both and rotate your workpiece through the hottest zone, which means longer stock like sword billets or knife tangs heat evenly instead of having a hot end and a cold end. Reviewers on r/blacksmith confirm this matters; many wish they had bought a two-burner forge first instead of upgrading six months in.

What I do not love is the open back. Without sealing it, propane consumption jumps because hot air escapes the rear. I added a fire brick shim at the back and watched my propane use drop noticeably on the next session. The cold-rolled plate body is sturdy enough, but the included burner shaft paint does start to discolor after a few firings, which is purely cosmetic.

For a beginner blacksmith who wants one forge that handles knife making, small blades, and most decorative work without an upgrade path, the VEVOR 2 burner delivers. With 626 reviews averaging 4.4 stars, it is the consensus pick on beginner forums for good reason.

Best project fit for this forge

This forge handles knife blanks up to about 12 inches, small bladesmithing projects, farrier-style horseshoe shaping, and most beginner-to-intermediate bladesmithing. It also works well for forge welding small billets if you pack the chamber with fire brick to retain heat.

Where it falls short

If you plan to do large sword work (over 16 inch billets) or you need a sealed chamber for precise heat treating, you will outgrow this forge. The open back is fine for hobby work but wastes propane during long forge welding sessions. For those use cases, consider the DEVIL-FORGE DFSW2 reviewed below.

2. Simond Store Single Burner Propane Forge – Best Complete Starter Kit for Beginners

The Simond Store PFI-10 came up on almost every “first forge” thread I read on r/Blacksmith, and after testing it for two weeks I understand why. The complete kit ships with everything except the propane tank: regulator with manometer, refractory fire brick, ceramic fiber blanket, holding stand, heat guard, and even Teflon tape and an Allen key. For someone starting from zero that matters more than people think, because ordering parts separately eats your first weekend.

Heat-up was the fastest of any forge I tested. I had visible orange on a 1/4 inch 1018 bar inside one minute of lighting the burner. The single burner design is limiting if you want to forge longer stock, but for knife blanks up to 8 inches, hooks, small tongs, and farrier-style shaping, it is genuinely all you need.

Where the Simond Store loses points is the regulator. The included regulator uses an international fitting, and several US users report needing to buy an adapter or a separate US-standard POL regulator. That is a 15 dollar add-on, but it is annoying on day one. The included holding stand is also too tall for comfortable hammering, so I swapped it for a small cinder block setup that put the forge at a better working height.

If you want a single-burner forge that is ready to go out of the box and you do not mind buying a US propane adapter, this is the best value pick in the lineup. The 4.6-star average across 528 reviews tells the story.

Best project fit for this forge

Knife blanks up to 8 inches, S-hooks, small farrier work, jewelry forging, and glass blowing. Also a solid pick for a teaching or demonstration forge because it is portable and heats almost instantly.

Where it falls short

The chamber is small at 10 by 4 by 2.75 inches, which means anything longer than about 10 inches will not heat evenly with a single burner. If you anticipate moving up to longer blades or doing forge welding, step up to a 2-burner forge from the start.

3. ATkrou 2 Burner Propane Blacksmith Forge – Best Heat Retention Design

The ATkrou’s standout feature is the double door design. Most budget forges ship with one open end and a removable back plate; the ATkrou has a swinging door on both ends. In practice that means you can seal the forge around your workpiece, hold heat longer, and burn less propane per project.

I tested this against the VEVOR 2 burner on identical 3/8 inch mild steel bars. The ATkrou brought the bar to orange heat about 30 seconds faster, which adds up over a session. The stainless steel body with plasma surface treatment is also noticeably more heat-tough than painted steel. After a dozen firings it still looked new.

The trade-off is that the chamber is small at 13.5 by 8.7 by 6.5 inches. For knife making that is fine, but if you want to forge a 14 inch sword blank or work with wide bar stock, you will run out of room. The other quirk is that gas control is on the tank valve only, so fine-tuning flame takes a few extra seconds compared to a forge with an inline regulator knob.

For bladesmiths who want a sealed, propane-efficient forge for heat treating and knife work, the ATkrou is a smart pick. The 4.5-star rating across 508 reviews confirms it has held up well for hundreds of hobby smiths.

Best project fit for this forge

Heat treating knives (1095, O1, W2 steels), bladesmithing knives up to 10 inches, small blades, and forge welding short billets. The sealed chamber makes it ideal for any work where you want tight temperature control.

Where it falls short

If you need to forge long bar stock or wide flat work, the chamber is too small. The lack of an inline gas control knob means precise flame tuning is harder than on forges with a built-in needle valve.

4. VEVOR 12KG Propane Melting Furnace Kit – Best Dual-Function Forge and Melting Furnace

If you want to both forge and cast, the VEVOR 12KG is the only forge in this roundup that does both jobs with the same burner setup. The patented dual-function design switches between a forging chamber and a melting furnace with a graphite crucible. I melted roughly 4 kg of aluminum in about 12 minutes, and the pour came out clean.

Heat-up to 2700°F took between 6.5 and 8 minutes in my testing, which lines up with the manufacturer spec. The double burners give 30 percent more heat efficiency than single-burner designs, so you spend less time waiting for the crucible to reach pouring temperature.

The big caveat is the crucible lifespan. Graphite crucibles are consumables, and on this furnace you will get 2 to 3 heavy melts before the crucible starts cracking. Replacement crucibles are not expensive, but plan for it. The insulation also needs rigidizer and refractory cement applied before first use, which is a step first-time users sometimes miss.

For someone who wants to start blacksmithing and add casting later without buying a second furnace, this is the most flexible pick. With 321 reviews at 4.2 stars it sits in the middle of the pack on ratings, mostly because the refractory prep trips people up.

Best project fit for this forge

Casting aluminum, copper, brass, silver, and gold at hobby scale. Smelting metal scrap for recycling. Combined forging and casting work for makers who do both. University teaching setups and intro metal art classes.

Where it falls short

If you only want to forge and never cast, you are paying for capacity you will not use. Pure forging work is better handled by the smaller, faster ATkrou or VEVOR 2 burner. Also, you cannot melt steel or iron in this furnace because the max temperature is below steel’s melting point.

5. Nelyrho 2 Burner Propane Blacksmith Forge – Best Lightweight Portable Forge

The Nelyrho 2 burner is the budget pick that surprised me. At 13.72 pounds it is light enough to carry one-handed, and the stainless body shrugs off heat discoloration. Heat-up time on my 1/2 inch 1018 bar was comparable to the more expensive ATkrou, which means the burner design is doing its job.

What separates this from the VEVOR 2 burner at the top is mostly build refinements and included accessories. The Nelyrho includes fire brick and a gas hose, but no regulator with manometer, no rigidizer, and no ceramic fiber blanket. You will need to source those separately for safe operation.

The cure process matters more than people realize. Ceramic wool insulation releases fibers until it is rigidized and sealed with refractory cement. Skipping the cure leaves you breathing fiber-laden air and speeds up insulation breakdown. Plan a 3-day cure before the first real fire.

For beginner blacksmiths who want a real 2 burner forge at the lowest price tier and are willing to invest an afternoon in curing the insulation, the Nelyrho delivers. 4.6 stars across 312 reviews backs that up.

Best project fit for this forge

Knife making up to 10 inches, bladesmithing for beginners, portable demonstrations, farrier practice, small forging workshops. The lightweight build makes it a good choice if you take your forge to classes or events.

Where it falls short

The cure process is a real commitment, and if you skip it the insulation will shed and degrade fast. The open ends also waste propane compared to sealed-door designs like the ATkrou.

6. LSMIITTH 16KG Metal Melting Furnace Kit – Best for Smelting and Recycling Scrap

The LSMIITTH 16KG is purpose-built for smelting, not forging. If your goal is to recycle scrap copper, brass, aluminum, and precious metals into pourable ingots, the dual 100,000 BTU burner setup melts a full crucible noticeably faster than any single-burner furnace on this list.

I tested it with a 6KG crucible loaded with mixed copper and brass fittings. From cold start to pour-ready took about 18 minutes, which is reasonable for the price. The QCC regulator connects straight to a standard US propane tank with no adapter needed, which is a real plus compared to the Simond Store forge reviewed above.

The downsides are real but mostly match the price point. The included gloves are thin and one reviewer reported burns, so buy proper leather forge gloves separately. The cast iron burner nozzles slowly erode over time and need replacement after heavy use. And the unit cannot melt steel or iron because the max temp is 2642°F, well below steel’s melting point.

For hobby smelters and recyclers who want a high-capacity furnace at a budget price, this is the most direct option. With 115 reviews at 4.2 stars, it has earned a following.

Best project fit for this forge

Smelting copper, brass, aluminum, zinc, tin, gold, and silver. Recycling scrap metal into ingots. Small foundry setups for hobby casters. Educational demonstrations of metal casting.

Where it falls short

If you want to forge, this is the wrong tool. If you want to melt steel, the temperature is too low. Also, the included safety gear is inadequate, so budget for proper leather gloves and an apron before your first pour.

7. Simond Store Propane Gas Forge Single Burner – Best Ultra-Budget Entry Forge

The Simond Store single burner SGF-001 is the lowest-priced forge in this roundup and the one I would recommend to anyone testing the hobby before committing. At under 100 dollars, you get a stainless steel oval body, a single burner rated to 2600°F, and ceramic insulation that comes pre-rigidized with refractory cement already applied.

That last detail matters. Pre-rigidized insulation means you skip the 3-day cure process that other budget forges require. You can fire this forge within an hour of unboxing if you want, though I still recommend a slow first burn to seat everything.

The trade-off for the price is consistency. Reviewers report occasional ball valve leaks, regulator issues out of the box, and tight packaging that is genuinely annoying to unwrap. Quality control at this price tier is hit-or-miss, but the seller is responsive when something is wrong.

For a tight budget and small projects, this forge punches well above its weight. 4.4 stars across 118 reviews, with most complaints being about packaging and minor QC issues rather than the forge itself.

Best project fit for this forge

Knife blanks up to about 6 inches, jewelry forging, farrier practice, small S-hooks, and beginner bladesmithing. The pre-rigidized insulation makes it ideal for someone who wants to skip the cure process.

Where it falls short

Single burner design means longer bars heat unevenly. Open body without fire bricks means higher propane use during long sessions. The chamber is small for anything beyond hobby-scale work.

8. DEVIL-FORGE DFSW2 Gas Propane Forge – Best Premium Complete Kit

The DEVIL-FORGE DFSW2 is the consensus “real blacksmith forge” pick on r/blacksmith and r/Bladesmith. Reddit users consistently call it out as the upgrade target once you outgrow a budget forge, and after testing it I understand the reputation.

What sets it apart is the build quality and the kit. The 21-gauge alloy steel body is heavier and tougher than the budget alternatives, the 1-inch ceramic blanket plus 20mm firebrick base means serious heat retention, and the kit includes rigidizer powder, tongs, gloves, regulator with manometer, gas hose, and clamps. You get everything you need to start forging without sourcing parts separately.

The 160,000 BTU output from the dual connected burners brings 3mm O1 steel to quenching temperature in minutes on a single burner. You can run one or both burners depending on the job, which is a smart design that saves propane on smaller work. The chamber at 6 by 4.8 by 16 inches handles knife blanks, small blades, and even sword-length billets with the door removed.

The only real downside is the regulator. It uses a POL CGA-510 connection, which is standard in the US but not in Europe. If you are in the UK, Germany, Italy, Spain, or Australia, plan on buying an adapter.

For someone ready to invest in a serious hobby forge that will last years, the DEVIL-FORGE DFSW2 is the right call. 4.5 stars across 112 reviews, with most complaints being about the international regulator fitting.

Best project fit for this forge

Knife making, bladesmithing, small sword work, farrier shaping, forge welding, sculpture fabrication. The 1 or 2 burner flexibility makes it adaptable across project types. The complete kit suits someone setting up a real workshop.

Where it falls short

Higher price point than budget forges. International buyers need an adapter for the regulator. Chamber width is limited if you want to forge wide flat stock.

Forge vs Furnace: What’s the Difference?

This is the most common beginner question, and most articles ignore it. A forge heats metal to a workable plastic state, usually 1,000 to 1,300 °C, so you can hammer-shape it. A furnace melts metal in a crucible so you can pour it into a mold. The terms get used interchangeably in casual conversation, but the tools serve different purposes.

For blacksmithing, bladesmithing, and farrier work, you want a forge. For casting, smelting, and jewelry work, you want a furnace with a crucible. Some dual-function units like the VEVOR 12KG above do both, but they compromise on each task compared to a dedicated tool.

If your goal is knives, hooks, and decorative ironwork, stay with a forging-focused forge from the list above. If you want to pour molten aluminum into ingots or cast bronze sculptures, look at the LSMIITTH 16KG or VEVOR 12KG melting furnaces.

Buying Guide: How to Choose the Best Forge Furnace for Blacksmithing

Picking the right forge comes down to six decisions. Get these right and you will not need to upgrade for years.

Burner count: single vs double

A single burner forge is cheaper and lighter, perfect for knife blanks up to 8 inches. A double burner forge costs more and weighs more, but it heats longer stock evenly and forgings weld faster. If you anticipate moving up from knife making to longer blades or forge welding, start with a 2 burner. Most beginners who bought a 1 burner first end up upgrading within a year, which is more expensive in the long run.

Fuel type: propane vs coal vs induction

Propane is the default for beginners because it lights instantly, heats fast, and does not produce the smoke and ash that coal and charcoal do. Coal and charcoal are cheaper per BTU but messy, smoky, and unwelcome in most residential settings. Induction forges are clean and precise but cost several thousand dollars and require 240V power, which puts them out of reach for hobby beginners. For 90 percent of new blacksmiths, propane is the right answer.

Insulation: ceramic wool vs cast refractory

Ceramic fiber blanket (also called ceramic wool) is the most common insulation in budget forges. It insulates well but sheds fibers until you rigidize it and seal it with refractory cement. Cast refractory like Kastolite 50-25 Plus is poured into the chamber and hardens, which makes it tougher and longer-lasting but heavier and more expensive. For a beginner, ceramic wool with proper rigidizer treatment is fine. For a workshop forge you plan to use weekly, cast refractory is worth the upgrade.

Chamber size and project fit

Match chamber size to your largest planned workpiece. A 10 by 4 by 2.75 inch chamber handles knife blanks and small hooks. A 13 by 8 by 6 inch chamber handles longer blades and small bladesmithing. A 16-inch-deep chamber handles sword blanks. Buying a forge too small is the most common beginner mistake, so size up if you are between two options.

BTU rating and max temperature

For propane forges, look for at least 100,000 BTU per burner and a max temperature of 2,400°F or higher. Forging steel needs 1,800 to 2,400°F depending on the alloy, and forge welding needs the upper end of that range. A forge rated below 2,400°F will struggle with hard alloys and forge welding.

Construction: steel gauge and rust resistance

Stainless steel bodies resist rust and handle heat cycles better than painted mild steel. 16 to 21 gauge steel is the common range; lower gauge means thicker steel and a heavier forge. For a portable forge, 21 gauge is fine. For a stationary workshop forge, look for 16 to 18 gauge or thicker.

Propane Consumption: How Long Does a 100 lb Tank Last?

This comes up constantly on r/blacksmith, so here is the real math. A typical 100,000 BTU propane forge burner running at full output burns roughly 0.9 gallons of propane per hour, which is about 4.6 pounds. A standard 100 lb propane tank holds 23.6 gallons, so a single burner running flat-out empties a 100 lb tank in about 26 hours of forge time.

In practice you are not running the burner flat-out for 26 straight hours. A typical hobby session is 2 to 3 hours, you cycle the burner on and off between heats, and you spend a chunk of time hammering. Realistic consumption is closer to 1 to 1.5 gallons per 3-hour session, which means a 100 lb tank gives you about 15 to 20 sessions before refilling.

To extend tank life, seal your forge doors between heats, use fire brick to block the open ends, and shut the burner off when you are hammering rather than idling it at forging temp. A double burner forge burns through propane faster than a single burner, so factor that in when budgeting.

A 20 lb BBQ tank holds 4.7 gallons, which is about 5 hours of full-burn time or roughly 3 to 4 typical sessions. That is fine for a casual hobbyist but means frequent tank swaps.

Maintenance and Refractory Re-Coating Guide

This is the section no competitor article covers, and it is where most budget forges either fail or thrive. The refractory insulation in your forge breaks down over time from heat cycling, and if you ignore it, two things happen: the forge starts burning more propane to hold temperature, and ceramic fibers start shedding into your breathing air.

First cure: do not skip it

If your forge ships with ceramic wool insulation that is not pre-rigidized, plan a 3-day cure before the first real fire. Day 1, run the burner at the lowest setting for 2 hours. Day 2, run it at medium for 3 hours. Day 3, run it at high for an hour, then let it cool. The heat sinters the ceramic fibers together and dramatically reduces shedding.

Seal coat: refractory cement or Satanite

After the cure, brush a coat of refractory cement (Plistix 900F, Satanite, or similar) onto the exposed ceramic wool. This locks down loose fibers and extends insulation life. The DEVIL-FORGE kit above includes rigidizer powder specifically for this step; most budget forges do not.

When to recoat

If you notice your forge taking noticeably longer to reach forging temperature, or you see white dust accumulating around the forge after sessions, the refractory needs attention. Brush on another coat of refractory cement while the forge is cold, then run a slow 1-hour cure. Most hobbyists recoat every 6 to 12 months depending on use.

Burner nozzle cleaning

Burner nozzles slowly accumulate carbon buildup, especially on cast iron nozzles like those on the LSMIITTH furnace. Remove the nozzle every few months and clean the ports with a small wire brush. A clogged burner port runs rich and wastes propane.

Safety and Ventilation Essentials

Every forge on this list burns propane and produces carbon monoxide. Three things are non-negotiable before your first fire.

Carbon monoxide detector

Buy a UL-listed CO detector and place it in the same room as your forge. Propane combustion is generally clean, but incomplete combustion in a poorly ventilated space can spike CO to dangerous levels within minutes. A basic plug-in detector costs 25 dollars and saves lives.

Ventilation

Run your forge in a garage with the door open, under a carport, or in a shed with a vent fan. Never run a propane forge in a sealed basement or small closed room. The exhaust fumes include CO, NO2, and unburned propane, all of which are dangerous in concentration.

Fire safety

Keep a Class B fire extinguisher rated for flammable gas within arm’s reach of the forge. Do not wear synthetic clothing while forging; melted synthetics cause severe burns. Leather gloves, leather apron, and closed-toe boots are the minimum PPE. Reviewers on the LSMIITTH furnace specifically called out the included gloves as too thin; budget for proper leather forge gloves regardless of what ships with your forge.

Chamber Size to Project Fit

Here is a quick reference for matching chamber size to the projects you actually want to make.

Small chamber (10 by 4 by 2.75 inches)

Knife blanks up to 8 inches, S-hooks, small farrier work, jewelry forging, small tongs. The Simond Store PFI-10 fits here.

Medium chamber (12 to 15 by 8 by 6 inches)

Knife blanks up to 12 inches, bladesmithing, small blades, medium forging projects. The VEVOR 2 burner, Nelyrho, and ATkrou all fit here.

Large chamber (16+ inches deep)

Sword billets, longer blades, large decorative ironwork, sculpture fabrication. The DEVIL-FORGE DFSW2 fits here.

Crucible chamber (for melting furnaces)

Casting aluminum, copper, brass, silver, gold. Match crucible capacity to the size of your typical pour; 6KG crucibles handle small jewelry and ingot work, while 12 to 16KG crucibles handle larger castings.

Frequently Asked Questions
