It can regulate the glaze slip viscosity,optimized rheological property and improve the associative property of semifinished product glaze ,enhance the strength of glazed,and regulate the glaze layer of drying time,obtain the smooth glazed surface.
The content of ground coat and overglaze is 0.08%-0.3% generally,less in winter . put CMC in the ball mill  to grind  together with other glazes , or add in 3-4 hours before leaving the ball mill .
