Pyrophyllite Basic information
Pyrophyllite is a phyllosilicate mineral composed of aluminium silicate

hydroxide: Al2Si4O10(OH)2. It occurs in two more or less distinct

varieties, namely, as crystalline folia and as compact masses; distinct

crystals are not known.
The folia have a pronounced pearly lustre, owing to the presence of a

perfect cleavage parallel to their surfaces: they are flexible but not

elastic, and are usually arranged radially in fan-like or spherical

groups. This variety, when heated before the blowpipe, exfoliates and

swells up to many times its original volume, hence the name of

pyrophyllite, from the Greek pyros (fire) and phyllos (a leaf) given by R.

Hermann in 1829. The color of both varieties is white, pale green, greyish

or yellowish; they are very soft (hardness of 1 to 1.5) and are greasy to

the touch. The specific gravity is 2.65 - 2.85. The two varieties are thus

very similar to talc.
