Terracotta is clay that has been refined, molded into a shape and fired. It has been used for thousands of years all over the world for pipes, roof tiles, tableware, sculptures, and of course, pots. Unglazed terracotta pots are popular because they come in all sorts of sizes, shapes and styles and are very affordable. Terracotta was the only ceramic produced by Western and pre-Columbian people until the 14th century, when European higher fired stoneware began production. Terracotta has been used throughout history for sculpture and pottery, as well as bricks and roof shingles.
Soapstone, also known as steatite, can be found all over the world. Much of the soapstone seen these days comes from Brazil, China or India. Significant deposits also exist in Australia and Canada, as well as in England, Austria, France, Italy, Switzerland, Germany and the United States. Stones from different countries have different properties, but all are geologically stable, solid and not affected by humidity, therefore objects carved from soapstone last a very long time. Soapstone is a metamorphic rock composed of several minerals including magnesite, dolomite, cholrite, and talc.
