Pyrophyllite. Pyrophyllite is an aluminum silicate mineral with a similar chemical structure to talc (a magnesium silicate). It is non-plastic yet clay-like and often used in ceramic bodies to decrease thermal expansion and moisture expansion during service. It is a very soft white mineral (also resembling talc in physical appearance and feel).

Hardness: Pyrophyllite falls under the category of soft minerals. On the Mohs scale of mineral hardness, it has a value of 1-2, which is similar to the hardness of talc. Specific Gravity: It has a specific gravity of around 2.65 to 2.85, which is considered low to average for most minerals.
