[Gasification] Dolomite

[Benjamin Domingo Bof]

Doctor Thomas B. Reed and Toby Seiler; perhaps "soaprock" or "steatite" with higher magnesium part could give an very good filter for tars. An copy of "wiki" says:
It is relatively soft (because of the high talc content, talc being 1 on Mohs hardness scale), and may feel soapy when touched, hence the name. Soapstone is used for inlaid designs, sculpture, coasters, and kitchen countertops and sinks. Traditional Inuit carvings often use soapstone, and some Native American groups made bowls, cooking slabs, and other objects from soapstone, particularly during the Late Archaic archaeological period. Due to its chemical stability and resistance to acid, soapstone is the most commonly used material for chemistry lab counter and sink surfaces.[citation needed] Soapstone is sometimes used for fireplace surrounds and woodstoves because it can absorb and evenly distribute heat while being easy to manufacture. This is found in some Alaskan homes. It is also used for griddles and other cookware.
 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[1]
 Soapstone has been used in India for centuries as a soft medium for carving, but unfortunately the world wide demand for soapstone is threatening the habitat of India's tigers.[2] The Hoysala Empire temples were made from soapstone.[3]
 Soapstone markers are used by welders and fabricators as a marker because, due to its resistance to heat, it remains visible when heat is applied.[citation needed] Soapstone is used to create molds for the casting of pewter objects.
 Soapstone smoking pipes are found, for example, in Native American Indian artifacts.[citation needed]
 Locally quarried soapstone was used as gravemarkers in 19th century northeast Georgia around Dahlonega and Cleveland, as simple field stone and "slot and tab" tombs.

 The term steatite is sometimes used for soapstone. It is also a type of ceramic material made from soapstone with minor additives and heated to vitrify (to change or make into glass or a glassy substance, especially through heat fusion). 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. It was used for beads and seals in ancient civilizations. 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 from 1 to 5.5-6.5.[4]

  Is not high calcium limestone about the same as dolomite less the magnesium, lead and other small constituants of metals?
