Talc. Standard hydrated talc is one of a family of insoluble mineral magnesium silicates. It is a soft, greasy, platy or fibrous mineral. Talcs useful in ceramics are considered to be the "high aspect ratio" (very platy) grades. Geologically talc is closely related to chrysotile asbestos and soapstone. The mineral itself can range in color from ...
