Details
OM#4 is a white-firing ball clay that works well in decorating slips, engobes, and moist clay bodies for throwing and hand building. It is also widely used as a suspension agent in glazes. Ball clays generally impart plasticity to clay bodies and typically have a large variation of particle size.
