Abstract: Cellular ceramic materials, for example closed cell glass ceramic materials, for use in construction of buildings comprising a clay material, carbon, and water used to form the cellular ceramic blocks, slabs and beams by expansion of the particles inside the ware. The cellular ceramic materials are produced by first mixing the clay, carbon and about 40% to about 70% water by weight of the clay in the mixture, allowing the mixture to cure, drying the cured mixture, then firing the dried mixture at a temperature and for a period of time sufficient to melt the surface of the mixture. The clay material can be, for example, surface clays, ball clays, kaolin, shale, fly ash and/or bentonite. In another embodiment a mixture of volcanic ash, carbon and water can be formed and layered with the mixture of clay, carbon and water.
