Talc, Mg 3 Si 4 O 10 (OH) 2, is always found in metamorphic settings. Talc is the softest mineral, the standard for hardness grade 1 in the Mohs scale. Talc has a greasy feel and a translucent, soapy look. Talc and pyrophyllite are very similar, but pyrophyllite (which has Al instead of Mg) may be slightly harder. Talc is very useful, and not just because it can be ground into talcum powder -- it's a common filler in paints, rubber, and plastics too.
