    摘要： A method for producing a foam glass tile having a surface skin comprises the steps of molding a material consisting essentially of a vitrifiable mineral and a foaming agent into a tile-like block; coating the block with a thin layer comprising a vitrifying agent for the mineral material; heating the coated block to a temperature sufficient to fuse the coated layer whereby the molten vitrifying agent permeates into the coated surface of the block; and further heating the coated block to a temperature sufficient to soften the vitrifiable mineral. The method may further include the step of forming a thin layer comprising a vitrifiable mineral and a lesser amount of a foaming agent between the tile-like block and the vitrifying agent layer, followed by firing. The foam glass tile formed by the above method comprises a foam glass tile body and a rigid reinforcing vitrified surface skin, the surface skin being integrally melt-bonded onto at least a top surface of the foam glass body. Such foam glass tiles have a closed cell structure and are thermally insulating.
