What Is Porphyry Stone?
Porphyry is a type of igneous rock. The significance of igneous rocks is that they are comprised of large crystals, usually quartz and feldspar crystals called phenocrysts, of greater than 2 millimeters which can be seen by the human eye. These larger crystals are mixed with tiny crystal materials called the groundmass to form an igneous rock.
The formation of natural porphyry deposits is a two-phase process. Hot magma mixes with overlying rock material to form the larger crystals, then when the magma spits out of the volcanic origin, it mixes with the tiny crystal groundmass and cools very quickly to form the igneous rock structure.
History of Porphyry
The ancient Egyptians were one of the first people to quarry porphyry stone successfully. Egyptian kings and queens were the exclusive benefactors of porphyry works and masterpieces.
In about the year 300 A.D. the ancient Romans used porphyry to decorate royal palace rooms for family members of the royal empire. King Louis the fourteenth of France is known to have owned the world’s largest collection of porphyry stone.
Variety of Porphyry
There are many varieties of porphyry stones and their name is derived from the character of the phenocrysts (large crystals) in the groundmass. They are found in main classes of igneous rocks such as granite, syenite, diorite, gabbro, and peridotite.
