Pyrolave’s custom sinks are made with lava stone extracted from volcanic craters in France’s Auvergne region. The hard, dense stone can be shaped into nearly any configuration without seams or joints. Coated with durable enamel in one of 16 matte or 16 glossy colors, the finish delicately crazes during cooling for a one-of-a-kind result. Pyrolave. U.S.A. 919.788.8953. www.pyrolave.com.
