Soapstone (also known as steatite or soaprock) is a talc-schist, which is a type of metamorphic rock. It is largely composed of the mineral talc and is thus rich in magnesium. It is produced by dynamothermal metamorphism and metasomatism, which occurs in the areas where tectonic plates are subducted, changing rocks by heat and pressure, with influx of fluids, but without melting. It has been a medium for carving for thousands of years.
Petrologically, soapstone is composed dominantly of talc, with varying amounts of chlorite and amphiboles (typically tremolite, anthophyllite, and magnesiocummingtonite), and trace to minor FeCr-oxides. It may be schistose or massive. Soapstone is formed by the metamorphism of ultramafic protoliths (e.g. dunite or serpentinite) and the metasomatism of siliceous dolostones.
Pyrophyllite, a mineral very similar to talc, is sometimes called soapstone in the generic sense since its physical characteristics and industrial uses are similar,[citation needed] and because it is also commonly used as a carving material. However this mineral typically does not have such a soapy feel as that from which soapstone derives its name.
Physical characteristics
Steatite is relatively soft (because of the high talc content from which it was originally comprised has a definitional value of 1 on the Mohs hardness scale), and may feel soapy when touched, hence the name.
The term steatite is sometimes used for soapstone. It is often used as an insulator or housing for electrical components, due to its durability and electrical characteristics and because it can be pressed into complex shapes before firing. Steatite undergoes transformations when heated to temperatures of 1000–1200 °C into enstatite and cristobalite; in the Mohs scale, this corresponds to an increase in hardness to 5.5–6.5.
Historical uses
The 21st-century BCE statue of Iddi-Ilum of Mari is made of soapstone
Soapstone is used for inlaid designs, sculpture, coasters, and kitchen countertops and sinks. The Inuit often use soapstone for traditional carvings. Some Native American tribes and bands make bowls, cooking slabs, and other objects from soapstone; historically, this was particularly common during the Late Archaic archaeological period.
Locally quarried soapstone was used for gravemarkers in 19th century northeast Georgia around Dahlonega and Cleveland, as simple field stone and "slot and tab" tombs.
Vikings hewed soapstone directly from the stone face, shaped it into cooking-pots, and sold these at home and abroad.
Soapstone is sometimes used for construction of fireplace surrounds, cladding on metal woodstoves, and as the preferred material for woodburning masonry heaters because it can absorb, store and evenly radiate heat due to its high density and magnesite (MgCO3) content. It is also used for counter tops and bathroom tiling because ot the ease of working the material and its property as the "quiet stone." A weathered or aged appearance will occur naturally over time as the patina is enhanced. Applying mineral oil simply darkens the appearance of the stone; it does not protect it in any way.[citation needed]
Tepe Yahya, an ancient trading city in southeastern Iran, was a centre for the production and distribution of soapstone in the 5th–3rd millennia BC.
It was also used in Minoan Crete. At the Palace of Knossos, archaeological recovery has included a magnificent libation table made of steatite.
The Yoruba of West Nigeria utilized soapstone for several statues most notably at Esie where archaeologists have uncovered hundreds of male and female statues, about half of life size. The Yoruba of Ife also produced a miniature soapstone obelisk with metal studs called superstitiously "the staff of Oranmiyan"
The outer layers of the Christ the Redeemer sculpture are made of soapstone. Rio de Janeiro
Modern uses
Soapstone has been used in India for centuries as a medium for carving. Mining to meet world-wide demand for soapstone is threatening the habitat of India's tigers.[6] The Hoysala Empire temples were made from soapstone.
In Brazil, especially in Minas Gerais, due to the abundance of soapstone mines in that Brazilian state, local artisans still craft objects from that material, including pots and pans, wine glasses, statues, jewel boxes, coasters, vases. These handicrafts are commonly sold in street markets found in cities across the state. Some of the oldest towns, notably Congonhas, Tiradentes and Ouro Preto, still have some of their streets paved with soapstone from colonial times.
Some Native Americans use soapstone for smoking pipes; numerous examples have been found among artifacts of different cultures and are still in use today. Its lack of heat conduction allows for prolonged smoking without the pipe's heating up uncomfortably.
Soapstone is also used to carve Chinese seals.
Currently, soapstone is most commonly used for architectural applications, such as counter tops and interior surfacing.
Welders and fabricators use soapstone as a marker due to its resistance to heat; it remains visible when heat is applied. It has also been used for many years by seamstresses, carpenters, and other craftsmen as a marking tool because its marks are visible and not permanent.
Soapstone can be used to create molds for casting objects from soft metals, such as pewter or silver. The soft stone is easily carved and is not degraded by heating. The slick surface of soapstone allows the finished object to be easily removed.
Soapstones can be put in a freezer and later used in place of ice cubes to chill alcoholic beverages without diluting. They are also known as whiskey stones.
