That works very well. Kaolinized?
The way I saw it; Kaolinized means "turned to clay";; Dictionary says: kaolin |ˈkāəlin|nouna fine, soft white clay, resulting from the natural decomposition of other clays or feldspar. It is used for making porcelain and china, as a filler in paper and textiles, and in medicinal absorbents. Also called china clay.Derivatives: Kaolinize-verb
