CT 3 with Grog
- CT3 Grog low fire white is in stock!
- The CT3 formula has been updated and is no longer gray. This low fire clay is now a white clay in the raw form! Still Bisque at 06 and glaze 06-04!
- CT 3 with GROG is a medium coarse white firing clay, suitable for hand building, sculpture and tile work.The grog is added for more even drying and give an additional touch of strength. Very popular with beginners and used widely in local schools.
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.
