Discover classic beauty and proven durability with Lopi's Sturbridge freestanding, cast iron gas stoves with our new Antique Slate porcelain enamel finish! An ancient art, porcelain enamel is applied as powdered glass. When fired in a kiln at temperatures up to 1650ºF, the powdered glass melts and flows across the cast iron, firmly bonding with the base metal. Lopi's Antique Slate enamel is a soft gray-blue tone, the result of a unique double layer application process. As the color layer flows over the cream-colored base layer, edges and design highlights are revealed as a paler tone. The process transforms the Sturbridge into an example of true hand-made craftsmanship. This is tomorrow's heirloom with today's state-of-the-art gas technology. Comforting warmth never looked so good.
