Grogs are used to produce openness of texture in clay bodies, aid drying and reduce shrinkage and warping (usually up to 20%). The texture is modified according to the mesh size of the grog used. Red grog is used as a low temperature flux which helps prevent crazing. It is only for use in earthenware.
