Low-fire bodies are defined by when the temperature at which the clay body matures, generally considered to be between cones 09 and 02 (1700 and 2000 degrees F or 927 and 1093 degrees C). Low-fire clays tend to have good workability and usually will not shrink, warp, or sag excessively.

What is considered low fire clay?

Low fire clay reaches maturity when it is fired, between 1940 -2109F (1060-1154C). On the cone system, this is between cone 04 and 1. These are often referred to as ‘earthenware temperatures’ because earthenware is the term used for low fire clay.

What temperature is fire clay fired at?

It may cause a house fire. The temperatures needed to fire clay are too hot (1,000 F degrees and hotter). This temperature would make any stove red hot and it would exceed the safety designed into any stove. This is much hotter than a self-cleaning oven reaches when it burns the residues in a dirty oven.

What temperature is high fire clay?

The average firing temperature for high-fire stoneware is 2381℉ (1305℃). However, anywhere from 2305℉ to 2336℉ (1263℃ to 1326℃) may be appropriate depending on the specific clay used and desired effect.
