Annealed float glass is the plain glass product that most people picture when thinking about glass. Annealed (float) glass is produced by melting sand, soda ash, dolomite, and limestone together to produce a continuous ribbon which flows from a furnace and “floats” over a bed of molten tin, which is then carefully cooled to “anneal” the glass. When tempered glass breaks, it breaks into small pebble shaped pieces like a cars windshield after an accident. Float glass also called as flat glass is annealed glass (not tempered or heat strengthened) and is produced by controlled cooling to prevent residual stress in the glass. Lower internal stresses make annealed glass suitable for all fabrication prior to tempering. It is flat, fire-finished on the top, and has smooth, parallel surfaces.
