Earthenware clays were some of the earliest clays used by potters, and it is the most common type of clay found. These clays are highly plastic (easily worked) and can be sticky. Earthenware clays contain iron and other mineral impurities which cause the clay to reach its optimum hardness at between 950°C and 1150°C.

Low-fire clay can be fired up to Cone 3, or sometimes a little higher. Unlike mid and high fire, it never shrinks much or gets really strong and dense even when fired to its maximum temperature. The main advantage to using a low-fire clay when low firing is that your glazes may craze less than if you used a Cone 10 or Cone 6 clay.

As always, you have to fire your glaze to the Cone that is specified for that glaze, regardless what clay you use. Just make sure you use a clay rated at least as high as the glaze.
