A.R.T. Moist Clay Brownstone I

This is a warm, reddish-beige clay body when fired to cone 5. Its slight tooth is derived from the addition of 65 mesh sand and extra-fine grog. Compatible with Glazewerks lead-free stoneware glazes as well as most commercial cone 5–6 glazes, A.R.T. recommends bisque-firing Brownstone I to cone 04–03, and glaze-firing it to cone 5–6.

A.R.T. Studio Clay Company formulates its clay bodies using a principle called “multiple similar clays.” By blending comparable clays together, the company’s dependence on just one mine or one clay is greatly reduced. The obvious advantage of this method is a higher consistency from batch to batch.

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.
