Ever Wondered How a Car Windshield is Made?
The glass formula ingredients and water are mixed together in a refractory tank where they are subjected to very high temperature and melted.

From this chamber, the long sheet of molten glass is transported on rollers into another chamber, where a special furnace starting the process of gradually cooling the glass. This is called annealing. At the end of this process, this 'raw' glass will now be used to make windshields from.
Using a diamond cutting tool called a 'scribe', the now cooled glass is cut to the required dimensions. Next, it is shaped when placed on or into a mould with the desired curvature and shape. When it is heated just to the point it becomes soft but does not melt and, as a result, sags on or into the mould. Then it is cooled extremely quickly by shooting jets of cold air on it. This tempering process greatly strengthens and hardens the glass.
The last step for the windshield glass occurs when two sheets of tempered glass are put on each side of a very thin layer of Poly-Vinyl Butyral (PVB). This sandwiched glass is heated in pressure chamber and pressed between rollers,making the PVB transparent. This final step fuses the glass sheets and PVB into a single slab of laminated safety glass.
