The heat quality of stone is gentle, even and comfortable; you can sit close to a soapstone stove without getting the uncomfortable blast of heat you would feel from steel. The surface temperature is also less hot, which is a safety advantage, particularly for homes with young children.
Soapstone also has attractive veining and other naturally created patterns, which are one-of-a-kind decorative elements. When it is exposed to high temperatures, its rich colors can actually deepen over time.
HearthStone soapstone stoves use a combination of materials to maximize the benefits of each. For instance, soapstone plus cast iron gives you the immediate radiant heat of cast iron, something to curl up to, while the natural stone slowly releases its gentle, stored heat over time.
