Best Propane Gas Forge Buying Guide

We made a list of the essential points you should know before buying one of the best gas forges for knife making. We recommend you to have a look at the gas forge buyer’s guide below.


Shape and Size

Gas forges are available in different forms. The common types are the box, vertical tube, horizontal tube, and more. You can choose the one you want because that will not make any considerable difference.

The size of the forge is a vital thing to consider. Make sure the volume is large enough so that you can forge swords, Damascus billets, and odd shapes efficiently with less effort. 

Burner and Regulator

There are two types of burners available for a gas forge – Venturi and Forced Air. Venturi burners are simple, easy to operate, quiet, and safe. Forced air burners are more efficient but costly, loud, and less secure.

Most of the blacksmiths use the Venturi burners for their gas forges. A single burner forge will not provide excellent performance; a minimum of two will be efficient for forging. 

You can use any regulator – double gauge or single gauge. But for a gas forge, a propane specific two gauge regulator that will show you inlet and outlet pressure will be a wise choice. 

Insulation

Insulating fibers, firebricks, and castable refractories – these are the three common types of insulations for a gas forge. Insulating fibers are excellent; they do not absorb that much heat but don’t last long.

Firebricks come in different grades – soft, hard, etc. It will take more time than the insulating fibers to come up to an efficient temperature for forging. Castable refractories last long, but they absorb lots of heat, and the forge will take more time to reach a certain level of temperature.

Knife Making Gas Forge FAQs

Q. What is a Gas Forge?

A gas forge is an essential tool for a Blacksmith to heat metals for forging. It uses natural gas or propane gas as fuel. Gas forges are available in different shapes – box, vertical, horizontal, etc.

Q. How a Gas Forge Works?

Gas forges use propane or natural gas to make the fire for heating metals. Gas flows from a tank to the forge through a burner. You can control the gas flow by a regulator. Once gas starts to flow into the forge, you’ll need to fire it up, and the forge will begin heating up. Different kinds of insulators are used inside the forge to maintain the temperature.

Q. How hot does a gas forge get?

A quality Gas Forge temperature can climb between 1200 – 1500 degrees Celsius. If it’s only air your forge is getting from the choke point, the temperature will be a bit low. On the other hand, pure oxygen will increase the temperature rapidly.

Q. How much propane does a gas forge use?

The answer to the question will always depend on various factors like PSI and how frequently you are using the forge. On average, you could use around 2.5 pounds of gas per hour at 8 PSI.

Q. How long will a 20-lb propane tank last in a gas forge?

From a 20 lb propane tank, you would be looking at 7 to 8 hours of continuous usage. That’s very decent for many hobbyists who spend only a few hours in the shop.

Q. What is a Gas Forge Burner?

A gas forge burner provides heat into the forge. Gas flows from a gas tank to the forge chamber through the burner. Forge burners are available in two types – Venturi and Forced Air. 

Q. What Regulator for Gas Forge?

A propane specific dual gauge regulator is the right choice for a propane gas forge. You can also use any regulator, and that will work just fine. 

Q. Gas Forge Vs. Coal Forge – Which is better for you?

For a beginner, the gas forge is the right option to start. If you want to forge regular-shaped metal, it will work fine for your needs. On the other hand, a coal forge is versatile. It’s a great option to work with odd-shaped items that require a localized heat zone. Coal forge produces smoke, and the shop gets dirty. To use a coal forge, you’ll need to know how to control the fire.
