Grog Hi-Pur 5'S-Dust
Grog provides texture. Grog is an opener which helps the clay to dry uniformly and cuts down the overall shrinkage and hence any tendency to crack and warp.
Manufactured using calcined china clay which is a refractory white grog. Fine grades are used to reduce shrinkage of engobes and to increase resistance to thermal shock. Coarser grades are used in clay bodies such as Earthstone.
