Glass is made from sand or silica mixed with soda ash, limestone, dolomite, and glass shards about 30 percent by mass of a substance that, when added to all this, it reduces the temperature of the molten silica, from about 1500 to 1600 degrees to 1700 degrees and increase stiffness. of glass When objects are made of glass has been heated in a furnace at a temperature of 1600 degrees compounds including carbonate, soda ash, limestone, dolomite. Change and the resulting molten oxide is homogeneous, which is called water glass, then reduce the temperature of the water in a different glass. Glass viscosity prior to transport to the process of forming the desired products continue.
