Description
Devitrification occurs when the normally amorphous form of glass may slowly or rapidly becomes crystalline resulting in lost transparency and cohesive structure. Rapid devitrification may occur when molten glass is cooled too slowly thus allowing components to separate and crystallize. Slow devitrification may occur in moist soils or similar environments where alkaline components leach out, thus allowing the remaining silica-rich material to crystallize. Devitrified glass or ceramic glazes may appear to have a whitish haze or an iridescent sheen.
