Abstract
A foamed ceramic panel having a base layer comprising foamed inorganic raw materials and a fine glass layer comprising fused and solidified ceramic paper and formed on at least one surface of the base layer. A layer of heat-foamable inorganic raw materials and the ceramic paper laminated on the surface of the layer of heat-foamable inorganic raw materials are simultaneously burned and fused together. In producing the panel, the glossiness of the surface of the panel is improved by quenching the foamed panel and re-heating the same to a softening temperature. The panels are applicable to interior or exterior materials for various kinds of buildings, art ceramic panels for decoration, and the like.
