Finnish soapstone was formed during the folding of the Karelian mountain range. In the process, it developed a special toughness that makes it both fireproof and easy to work with. It is also an excellent heat accumulator, which makes it ideal for use as a massage stone. Ours comes from a manufacturer in northern Karelia. Before using the stone for a massage, place it on the sauna bench or put it in a heat-resistant container and pour boiling water over it. The stone is at the right temperature when the water has cooled down so much that you can remove it with your bare hand. Then apply some massage oil to the skin and massage it in with circular, gentle movements of the stone. After use, the stone can be cleaned by hand with washing-up liquid or in the dishwasher.
