Diorite
Categories:	Ceramic
Material Notes:	Igneous rock, with a grain size 1- 3 mm (hypabyssal). It is intermediate in the acidic-basic range, with a total silica content of 55-65%. Predominant minerals in this generally medium-dark colored rock are hornblende and plagioclase feldspar. Property values are typical of Diorite used in construction. Actual property values will vary from sample to sample.
