A true refractory California ball clay mined and manufactured by Industrial Minerals. Contributes to clay bodies the same essential good workability properties typical of more costly Kentucky ball clays, yet imparts its own unique character of low shrinkage.

Minus 200 mesh: 99%
Water of Plasticity: 36%

Shrinkage:
Dry - 7.4%
Cone 5 - 10.7%
Cone 10 - 12.0%

M.O.R.
Dry - 200
Cone 5 - 4490
Cone 10 - 4730

Absorption:
Cone 5 - 15.2%
Cone 10 - 9.9%

Color:
Cone 5 - cream
Cone 10 - lt. tan

SO3 content: less than .4%
