Description

A general class of minerals that produce a fine white powder when ground, such as Chalk, Seashells, Kaolinite, Gypsum, Huntite, and Diatomaceous earth. White earths have been used directly as pigments, extenders and as a base for some lake pigments.

It is not the same as Terra alba (Mayer 1969).
