Soapstone is found in lots of places, a large amount of architectural grade soapstones comes from Brazil, China and India. it is also found in other parts of the world and most of it is exported to Europe. The production in Canada started in 1871, it is a metamorphic rock.
Some soapstone contains a hard, unreactive, colourless compound known as silica which can cause silicosis when inhaled. Silicosis is lung fibrosis caused by the inhalation of dust containing silica, According to the NHS - Once Silica is inside the lungs, the dust particles are attacked by the immune system. This causes swelling (inflammation) and gradually leads to areas of hardened and scarred lung tissue (fibrosis).
Lung tissue that's scarred in this way doesn't function properly. It is a condition that can get worse, Silicosis can also increase your risk of getting other serious and potentially life-threatening conditions. The people that are at risk of developing this condition are the creators that carve the material, however, as long as they use the right safety precautions there is no problem.
It is not as serious a hazard as asbestos. Granite, for instance, contains a lot of silica, but it may be carved safely if proper precautions are followed. Soapstone is also known as steatite (Talc rock) - It is still used for talcum body powder today. All sorts of products are made from soapstone from kitchen worktops, oil burners, flooring tiles, sinks. Carving soapstone can be harmful to health, so it is recommended to leave it to the professional who knows what they are doing, that have had the correct safety training in dealing with this material properly.
