This clay contains the same popular low fire white formula as the original CT-3, however we have added a special blend of medium to coarse particle size grog (a high temperature heat resistant inert material that reduces shrinkage and warping in the clay) adding strength to the clay. CT-3 with grog is a unique blend of clays and raw materials resulting in a superior clay body suitable for hand building and working on the wheel.

The new formula of CT3 Grog has higher absorption then previously. This is due to the formula shifting away from the gray talc. It still has excellent glaze fit and should be sealed with a glaze for functional-ware. Unglazed pieces can be sealed with an outdoor paver/stone sealer, but will not be food safe.
