Are there propane kilns?
Some models are available in either natural gas or propane. These gas kilns are used when you desire a reduction environment.
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 does a propane kiln work?
Gas kilns run on natural gas and fire in reduction, which doesn’t allow oxygen in during firing. Reduction firing results can be unpredictable, but typically yields rich, earthy colors. It’s difficult to maintain consistency, so gas kilns are most ideal for one-of-a-kind creations.
How much does it cost to run a gas kiln?

How hot can a propane kiln get?
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 long does it take to fire pottery in a gas kiln?
The first firing, or bisque fire, takes around 8-10 hours. And the second, or glaze firing takes around 12 hours. So, in total, it takes about 22 hours to fire clay in a kiln.

The benefit of a gas kiln is that you can control the atmosphere that the piece will be exposed to, which effectively affects the final outcome of glaze and clay bodies.
Is it expensive to run a kiln at home?
Kilns have a reputation for requiring costly amounts of electricity, and many hobbyists give this drawback as a rationale for using a communal studio instead of starting their own personal home studio.
Can I put a kiln in my house?
It is entirely possible to have a pottery kiln at home. To use a kiln at home you need 18 inches of clearance around the kiln. You also need to ventilate the heat and fumes from the kiln effectively. Additionally, your electricity supply needs to be enough to power the kiln.
