This is important to note because the chemical and physical makeup combines in such a way that it makes soapstone stand heads and shoulders above other stone home finish options. As an alternative natural stone kitchen counter instead of marble or granite, soapstone is often used because it is not stained with tomatoes, grape juice or wine. Its electrical properties are used as an insulator for the body and electrical components due to its durability and can be pressed in complex shapes before firing. Thick slabs of soapstone were often used to hold high-voltage equipment and wiring because soapstone is heat resistant and does not conduct electricity. Soapstone worked well for this type of cooking because it is heat resistant and can withstand the heat of a wood fire. The mold would be opened after cooling, the lead sprue would be cut from the bullet, and the bullet surface would be filed smooth. Native Americans in eastern North America used the An excellent electrical insulator. [4] Because it is composed primarily of talc it is usually very soft.

The people of Scandinavia began using soapstone during the Stone Age, and it helped them enter the Bronze Age As the name “soapstone” implies, it is soft to the touch because of its talc content, almost like touching a piece of dry soap. These properties make soapstone invulnerable to most physical damage. Soapstone with a fine grain size works best for highly detailed carvings. These areas of the Earth’s crust are subject to direct pressure and heat, thus metamorphosing periodites, serpentinites and dunites into soapstones. These two qualities combine in different ways, which gives each type of stone different properties. These properties make it useful for a wide variety of architectural, practical, and artistic uses.
