When choosing a clay, first determine what temperature range you will be firing. The temperature range you select is determined by the type of work you do and the equipment available to you. There are three basic temperature ranges: Low Fire/Earthenware Cone 06-3 (1850°F-2135°F) Mid Range/Stoneware & Porcelain Cone 4-7 (2160°F-2290°F) High Fire/Stoneware & Porcelain Cone 8-10 (2315°F-2380°F) *NOTE: High Fire clay bodies are often described as having a "wide firing range" (eg. Cone 2-10). Any clay body can be fired below its maturation point for various reasons, however it may not be suitable for functional ware when underfired in this manner. A High Fire clay may have a 2% absorption rating at C/10, but 6% or more at C/4. For functional work, a general guideline is that absorption should be 3% or less for stoneware and 1% or less for porcelain. A clay that is too porous will tend to absorb excess moisture and contaminants during use. Underfired clay bodies also tend to have more glaze/body fit problems such as crazing. A crazed glaze allows moisture and contaminants to seep through into the underlying clay and become trapped, causing premature weakening of the piece and possible bacterial growth if food items are involved. We have found that using glazes and clays formulated to mature at the same temperature reduces the occurrence of some of these problems when durable, functional work is desired.
