CMC can make the glaze smooth and improve the quality of the glaze through its bonding, water retention and suspension properties. CMC can enhance the plasticity of clay materials, improve the shape, increase the pressing strength, and greatly reduce the breakage rate. As a highly efficient bulking agent, it has no residue after firing and no side effects. Compared with other bulking agents, the amount added is small.
