What is unique about gas kilns?
Gas kilns are the most popular type of fuel kilns used today. Gas kiln firing has become popular among contemporary potters and ceramic artists who wish to use fuel-burning kilns because they don’t require constant stoking and they don’t create unburned ash residue. Most gas kilns are fueled by natural gas or propane.
How do you make a propane fired kiln?
The melting temperature of steel is around 2500F (1370C) (source). Most DIY propane kilns are used for quick low-fire pottery firing techniques like raku. These low fire methods are generally up to temperatures in the 1832F (1000C) range. Which is well within the temperature range of steel.
How much propane does a kiln use?
A soft brick gas kiln uses approximately 10,000 BTU’s per hour for every cubic foot for a cone 10 firing. A 30 cubic foot kiln will use 300,000 BTUs per hour to reach cone 10. Because you do not use the gas at full power for the whole firing, we will calculate for 6 hours of full power.
How many bricks does it take to build a wood kiln?

How much does it cost to have a kiln?
Now you have to add in the cost of wear and tear on your kiln. You can get scientific about this, figuring out the cost of replacement elements, etc. But I figure my kiln cost about $2000 and will last 400 firings (60% low fire/bisque, 40% mid fire). Or about $5 a load.
Can you bisque fire in a gas kiln?
Although you can bisque fire in either electric or fuel-burning kilns, electric is preferred. Fuel-fired kilns, such as those using natural gas or propane, tend to rise in temperature much faster due to the amount of fuel that must come through the fuel nozzle in order for the burner to remain lit.
