1. Pyrophyllite

   Pyrophyllite is a phyllosilicate mineral composed of aluminium silicate hydroxide: Al2Si4O10(OH)2. It occurs in two forms (habits): crystalline folia and compact masses; distinct crystals are not known. The folia have a pronounced pearly luster, 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 , exfoliates and swells up to many times its original volume, hence the name pyrophyllite, from the Greek pyro- (πυρο-, the combining form of πῦρ 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 1.0 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.

   Pyrophyllite is a natural occurring mineral, its composition is aluminum silicate hydroxide (Al2Si4O10(OH)2) and it is part of the phyllosilicate group of minerals. It is characterized by its white to yellowish color, its hardness is usually between 1-2 on the Mohs scale and it has an observable shimmer due to its lamellar or radial structure. It's often used in ceramic production, in the manufacturing of insulating materials, and as a component in insecticides and paints.

1. Pyrophyllite

   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 pyrophyllite, from the Greek pyros and phyllos, given by R. Hermann in 1829. The color of both varieties is white, pale green, greyish or yellowish; they are very soft and are greasy to the touch. The specific gravity is 2.65 - 2.85. The two varieties are thus very similar to talc.
