Cedar Heights Goldart is a selectively mined (in southern Ohio), plastic stoneware clay that 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 vitrifies to a light buff at cone 10R (the maximum range is not much beyond that).

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.

Goldart (left) compared to Plainsman Midstone (right). Goldart is a buff and vitreous stoneware at cone 10R. These are fired at cone 7, 8, 10 oxidation and 10 reduction (bottom to top). Soluble salts in the Goldart impart a darker coloration to the reduction fired bar). The Midstone has some coarser particles that make larger speckles in reduction.
