Conventionally calcined kaolin.
Burgess Icecap K, Iceberg and No. 30 calcined kaolins differ slightly in the pH, brightness, #325 residue, % free moisture. None of the differences should have significant effects on ceramic glaze and body applications.
However their Optiwhite thermo optic kaolins have the same chemistry but have an amorphous particle shape and lower specific gravity.
