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. However, they are softer which means that they are less durable and will absorb liquids.
Low-fire clays are divided into two types according to their color after firing. Darker-colored bodies (most commonly red), and the white and buff clay bodies.
