Grog, Christy 100M

Available from Seattle Pottery Supply when we last checked. Sold from the shop’s own store; the price there is the one that counts.

100 Mesh means the materials was passed through a 100 mesh screen at the Christy Minerals factory, and this is what fit through the screen. 100 Mesh is finer than 35 Mesh. Christy Grog is a fine, calcined clay product used in ceramics to add texture, reduce shrinkage, and improve thermal shock resistance in clay bodies. It is commonly used in stoneware, sculptural clay, and hand-built pottery to create grogged textures, strengthen the body, and reduce warping during drying and firing.
