A: ordinary flat glass and float glass are flat glass. Only the production process, quality is different. Ordinary flat glass is used quartz sandstone powder, silica sand, potassium fossils, soda ash, Glauber's salt and other raw materials, according to a certain proportion, by melting furnace high-temperature melting, through the vertical method or flat pull method, calendering process produced by transparent colorless flat glass.
B: Float glass is the use of sea sand, quartz sandstone powder, soda ash, dolomite and other raw materials, according to a certain proportion, through melting furnace high-temperature melting, glass liquid from the pool kiln continuous flow to and floating on the metal liquid surface, spread into a uniform thickness, through the fire polished glass belt, cooled after hardening from the metal liquid, and then by annealing cut into transparent and colorless flat glass.
