Notes
A large particle size kaolin intended for casting slips. It is low in plasticity and fires darker than most kaolins. Combining some of this material with other kaolins in casting recipes will tend to reduce casting times because of the greater permeability of the slip.
Kaolins of this type are also valuable for use in tuning the shrinkage and plasticity of slips which are applied to wet, leather hard or dry ware. Because their shrinkage is very low, they can be substituted for part of the regular kaolin and there will be minimal impact on the fired properties.
