Soda lime silicate glass (float glass): The raw materials are introduced as a mixture into the furnace where they are melted at a temperature of approx. 1,560 °C, genera lly using gas as an energy resource.The glass is shaped by distributing the mass of liquid glass over a bath of molten tin. The glass sheet is then cooled evenly and cut to size.Coated glass is float glass that has been coated with a metal-oxide-based coating using various processes (sputtering, evaporation, pyrolytic processes). The coating is a few atom layers thick.In the manufacture of ESG, float glass is heated to its transition temperature (min. 640 °C) and then rapidly cooled. This causes the su rfaces of the glass to cool and contract faster than the remaining material. This creates additional compressive strength in the surfaces that makes the resulting glass tougher.
