When deciding on a propane forge for your blacksmithing hobby, it’s important to have a clear idea of what your preferences and long-term goals are.

If not, you may wind up with a forge that underperforms, is poor quality, doesn’t reach optimal temperatures, or is too small for your projects.

As you review below the best choices available, carefully consider the following:

  • How small or large most of your projects will be.
  • What shape you prefer – cylinder, square, or rectangular.
  • The maximum temperature you’ll need for your work.
  • Safety features, such as doors and quality valves.
  • Overall dimensions that will fit your workspace.

Best Choice Overall

After looking at all the features and specs for the propane forges that made my top 7 list, I’d say your best bet is the Simond Store Blacksmith Single Burner.

It’s not too large, but it still is more than adequate for most forging projects, and when running, the sound isn’t too loud or obnoxious.

This forge is energy efficient, heats up quickly, and maintains a steady temperature, and with the added bonus of a handy tong rest, this choice is a winner all around.

Single Burner Propane Forges for Blacksmithing

Single-burner forges are smaller and more affordable than the double-burner options.

[amazon fields=”B07DJYMB2D” value=”thumb” image_size=”large” link_id=”14028″]

[amazon fields=”B07DJYMB2D” value=”button” link_id=”14029″]

This double burner forge is the top-rated forge for this list.

This unit can stand up to 2,300 degrees Fahrenheit and takes roughly 10 minutes to heat to the appropriate temperature.

This propane forge has a unique oval shape to maximize heat distribution to the unit’s center.

The wide mouth allows for maneuverability and increased efficiency for conserving fuel consumption.

It comes with two fire bricks and Hellcoat 3000 refractory coating to better protect the interior insulation.

Due to the forge’s shape, it is an ideal unit for blade work. You can choose to use either both or one of the burners for more direct heat application.

The design is longer than most double burner models at 19 inches, which allows for more creativity in your metalworking.

The Hell’s Forge doesn’t limit options and can support intermediate to advanced projects.


  • Size is great for most projects.
  • Heats up quickly.
  • Includes fire breaks. 


  • Doesn’t come properly sealed.
  • Regulator may leak.

[amazon fields=”B087RTKJLH” value=”button” link_id=”14031″]

The CMF 2000 can function as a double burner or a single. For smaller projects or maximum efficiency, one burner can be turned off to preserve fuel.

This forge reaches maximum temperatures of over 2,000 degrees Fahrenheit. Purchase includes two fire bricks, burner air-intake pipes, and a gas regulator.

Lined with Kaowool ceramic fiber, the CMF 2000 heats quickly and keeps the perfect temperature for any blacksmithing project.

It’s easier to use if you fashion an end piece for one of the openings to regulate airflow.

This particular forge does not come with an interior rigidizer or satanite, meaning that the ceramic fiber could be subject to damage from heat.

Separately buying a rigidizer and applying it yourself will prevent material fatigue.


  • Includes firebricks, burner air-intake pipes, and gas regulator.
  • Easy instructions for use.
  • US-based customer support team.


  • Must purchase a separate rigidizer.
  • Hard to get temperatures high enough.

The stainless steel exterior is five times as thick as the leading competitors to prevent material fatigue.

The interior is filled with a 1-inch ceramic fiber blanket and includes Hellcoate 3000 Refractory Coating to be applied by the customer after purchase.

The refractory coating is shipped as a powder and protects against 3,000 degrees Fahrenheit and tool insertion but also provides further reflection for increased temperatures.

Purchase includes two fire bricks and an upgraded 0-30 psi regulator. This forge is American-made.

By shipping the refractory coating in powder, the supplier protects the entire ensemble from potential damage so it can arrive safely at your door.


  • Carefully shipped.
  • American-made product.
  • Five times thicker steel.


  • Hard to maintain high temperatures.

Propane Forges Explained

Propane forges are gas-powered forges that hook up to propane tanks similar to a barbecue. 

Usually small enough to fit on a table or desk, propane forges are rectangular, oval, or round in shape and often don’t have doors.

For many, you can extend a working piece of metal straight through to the other side.

These open ends allow for airflow through the forge, which keeps the flames from going out.


Propane forges are made of thin metal exteriors and contain insulation all along the interior to create incredibly hot environments.

Most forges can reach interior temperatures of 2,000-2,600 degrees Fahrenheit.

Purchases frequently contain fire bricks that reflect heat onto the working metal for greater temperatures.

As fire bricks are made from materials with low thermal conductivity, such as ceramics, their use increases efficiency inside the chamber.


Safety is a huge issue with any kind of forge, but anyone using a propane forge needs to be particularly alert and careful.

Propane forges need good ventilation to prevent carbon monoxide poisoning. Gas leaks are also a risk if the valves or tubing happen to malfunction.

Similarly, the flame that burns is widespread and can take beginner blacksmiths by surprise.

Being aware of how the forge lights and how to avoid the flame is crucial to avoiding singes or burns.

Propane Versus Coal/Charcoal Forges

Propane forges are more commonly preferred over coal or charcoal forges, particularly if you are a beginner.

While propane forges are louder and have risks of gas leaks, coal forges are more difficult to control and contain dirtier elements.

Coal will burn hotter than propane but requires regular cleaning of the forge, which can be tedious.

Furthermore, there is more equipment required for propane forges, although propane is easier to obtain these days than coal or charcoal.

All in all, there are many advantages and disadvantages to both, but if you’re looking for a simple forge solution, propane forges require less skill to maintain.

Single Burner or Double Burner Forges

Propane forges have the option of one or two burners. A single burner forge contains a single propane hookup where the heat will enter the forge from a single entrance point.

This allows for a smaller forge and easier metalworking.

Beginners benefit from single burners because this concentrates the heat at a specific point, which is easier to manage.

Single burners are also ideal for small work that is also typically done by someone learning to forge.

A double burner forge is larger, more expensive, and usually not necessary for beginners or small metalwork.

With a double burner, heat is applied through two entrance ways into the forge.

A single propane tank is used to supply fuel, which flows to two separate burners to be lighted inside the forge.

Double burner forges accommodate larger metalwork pieces. They keep the entire forge hot so that longer pieces won’t cool in the air beyond a single burner.

Related Questions:

How Much Propane Does a Forge Use?

If your forge is functioning with 8 psi, a full 20-pound propane tank will last about seven to eight hours. Generally, forges work between 3 to 10 psi.

How Hot Do Propane Forges Get?

The interior heat depends on the forge, but the average maximum temperature for a propane forge is 2,300 degrees Fahrenheit.

Does a Propane Forge Need a Blower?

Propane forges do not need blowers to function. They are atmospheric, so they do not require additional air. 


Really, I don’t think you’ll be disappointed with any of the forges presented here.

Overall though, I think the Simond Store Blacksmith Single Burner is tough to beat.

It’s got it all: affordable price, quality parts, ideal size, steady temps, and easy setup. The convenient tong stand is the icing on the cake.

If you have your heart set on a double burner, I’d go for the Hell’s Forge Double Burner.

With a length of 19 inches, there’s plenty of room to heat long stock even with the firebricks in place.

The option of only using one burner at a time means that you’re almost getting two forges in one, which adds to the value tremendously.

Quality construction. Excellent heating. Versatile. Packaged carefully (even includes brush for applying cement!). You’ll love this beast!
