摘要：
A method of making a foamed glass body, including preparing an admixture of powdered glass, at least one carbonate based foaming agent, and at least devitrification inhibitor, heating the admixture to a first temperature to soften the glass, heating the admixture to a second, higher temperature to foam the softened glass into a foamed glass body, and cooling the foamed glass body. The crystal silica content of the so-formed foamed glass body is less than 1 weight percent.
