Lava, also referred to as Sicilian Ware, was the first American art glass. It was patented by Frederick Shirley, the general manager of Mount Washington, on May 23, 1878. This was a basalt-based glass with brilliantly colored flux imbedded into the surface. The glass is usually black but can be found in pink or cobalt. It often has gold decoration. A few pieces of Lava with enamel decoration are known to exist. The finish is almost always shiny but can be iridized.Very little of this glass exists today. Damaged and repaired. Measures approx, 5.5" tall.
