A.R.T. Moist Clay Brownstone I
Brownstone I is a medium firing clay good for smaller projects with a small firing range of Cone 5 to 6. The clay has a warm, sandy color with a reddish tint along with a good tooth combining fine mesh sand and grog for wheel throwing,. The second version, Brownstone II is slightly heavier, a better choice for large projects. While this brand doesn’t offer as many varieties of clay as others, it provides a good range of low, medium, and high fire clays.
