Cold Coaster is a minimalist design created by Stockholm-based designer Claesson Koivisto Rune. The Cold Coasters are made from solid Soapstone. What is especially appealing with soapstone is its unique heat permittivity; the ability to retain a temperature. So, placing the coasters in the freezer before use allows the stone time to accumulate a good chill. As a result, chilled drinks on a cold soapstone coaster hold their chill longer than drinks placed on a coaster at room temperature.
