This is a reddish-orange clay body when fired to earthenware temperatures (cone 04). The color deepens to a brick red if the firing temperature is increased to cone 3. This formula is blended with a moderate amount of 65 mesh sand and extra fine grog, which makes it an excellent choice for both hand-building and wheel-throwing. Slow bisque fire to cone 04–03.
In creating its clay bodies, A.R.T. employs a three-step processing system instead of the two-step process used by most clay manufacturing companies. The clay is dry-blended, then wet-blended, and finally de-aired in a five-function, two-level, industrial-size pug mill, which cuts, pelletizes, shreds, de-airs, and pugs the clay. Similar to the meters used to measure gasoline, the water meters used on A.R.T.’s wet-blending equipment are periodically cleaned and recalibrated to maintain accuracy.
All A.R.T. moist clays feature a usable shelf life of one year if stored in an airtight container in cool conditions.
