Sparq Whiskey Rocks are made by SPARQ USA in Colorado by the guys who know soapstone and understand its amazing qualities. These handy little rock cubes are eco-friendly, not only because they are reusable, but because they are manufactured with soapstone from factory excess. Soapstone is the only non-porous, odorless, tasteless, and a natural food-safe stone used in the home. Due to the high density of the material, soapstone retains temperature better than stones like granite or marble, so you can expect a sustained chill or heat.
