Cast, fused, and low temperature coated. Each type is further categorized, based on size, as large format, mosaic, or miniature mosaic. Cast glass tiles are formed in a liquid state at 1600°F or higher. Many cast glass tiles are WAVY in slightly textured, with inherent folds, bubbles, and creases. These unique characteristics are achieved through the casting process.
Fused glass tiles are typically made from sheet glass units that are altered through heat between 1023°F and 1599°F During manufacturing, different materials are glazed are fused to the sheet glass units, usually any multiple stages, to create a variety of colors and patterns. Used glass tiles can be smooth, textured, uniform, or non uniform.
Low temperature coated glass tiles are made from sheets glass units that are altered through heat and temperatures less than 1022°F. Typically, these alterations involve heat transference of coatings to the back of transparent sheet glass units. These coatings can contain wide varieties of color and patterns.
