ASTM C323 Chemical Analysis Testing for Ceramic Clays
ASTM C323 evaluates the chemical composition of the clays used in the production of ceramic whitewares. The method is used to determine the amount of moisture present on the surface, loss of ignition, and compositional analysis of the constituents of the clay sample in its standard air-dried form. The data obtained is used in the manufacturing, development, and research of ceramic clays.
