Soapstone

Meaning and Properties

History


Soapstone, also called steatite and known by regional and marketing names, has been in use for thousands of years. It gets its name because of its softness and "soapy" feel. Soapstone is nonporous and nonabsorbent, which makes it a good material for kitchen countertops and sinks. It is also used for insulating electrical components due to its low electrical conductivity. Soapstone is also used for construction of fireplace surrounds and with metal woodstoves. In the art world, soapstone is used for inlaid designs and sculpture with some Native Americans using soapstone for traditional carvings. In the 19th century, soapstone was used for grave markers in Georgia and Ohio.

Metaphysical Properties


Soapstone is commonly believed to have a soothing, balancing effect while creating a positive, calming energy. Soapstone is valued for it the way it helps one prepare for changes in life. It is also thought to promote truth, logic as well as rational and creative thinking. Soapstone’s physical benefits are said to be balancing the digestive system, reducing irritation and skin rashes, sun burns and allergies.


Geological Properties


Soapstone is a metamorphic rock that is composed primarily of talc. It is formed most often in areas of Earth’s crust that are subjected to extreme heat and pressure. Because of its high talc content, soapstone is a relatively soft stone with a Mohs hardness of 1 which makes it easy to carve. It is nonporous, nonabsorbent and heat resistant.

Soapstone is very soft with a Mohs hardness of 1, and should be treated with care. Clean soapstone with a soft dry cloth. Wash with warm, soapy water and a soft cloth or soft brush. Dry thoroughly.

Designing with Soapstone


While the color of natural soapstone tends toward lighter shades of gray, green or brown, soapstone can be coated to achieve brighter shades of those colors, making it ideal for autumn-themed jewelry. Soapstone also works well with designs with earthy tones and natural shapes such as, well, stones. Because the soft stone is easy to carve, it lends itself well to hand-carved figures such as birds.
