Notes
Cedar Heights Goldart is a selectively mined, plastic stoneware clay which is airfloated to 200 mesh particle size. It offers excellent working properties and has a wide firing range. It is balanced enough to be used alone. It fires to a light or golden buff and has a maximum firing range of cone 10-12.
Goldart has been used for many years in the pottery and ceramic industries as a body ingredient. It appears in many clay body recipes found in textbooks and magazines.
Cedar Heights Bonding is a 50 mesh version of Goldart.
