Stress from fasteners, plastic welding and molding render polycarbonate susceptible to stress corrosion cracking when it comes in contact with certain accelerants such as salt water and plastisol. It can be laminated to make bullet-proof "glass" , although "bullet-resistant" is more accurate for the thinner windows, such as are used in bullet ...
An example batch calculation may be demonstrated here. The desired glass composition in wt% is: 67 SiO 2, 12 Na 2 O, 10 CaO, 5 Al 2 O 3, 1 K 2 O, 2 MgO, 3 B 2 O 3, and as raw materials are used sand, trona, lime, albite, orthoclase, dolomite, and borax. The formulas and molar masses of the glass and batch components are listed in the following ...
Broadly, modern glass container factories are three-part operations: the "batch house", the "hot end", and the "cold end". The batch house handles the raw materials; the hot end handles the manufacture proper—the forehearth, forming machines, and annealing ovens; and the cold end handles the product-inspection and packaging equipment.
Soda–lime glass, also called soda–lime–silica glass, is the transparent glass, used for windowpanes and glass containers (bottles and jars) for beverages, food, and some commodity items. It is the most prevalent type of glass made. Some glass bakeware is made of soda-lime glass, as opposed to the more common borosilicate glass. [1]
Sodium silicate solutions can also be used as a spin-on adhesive layer to bond glass to glass [21] or a silicon dioxide–covered silicon wafer to one another. [22] Sodium silicate glass-to-glass bonding has the advantage that it is a low-temperature bonding technique, as opposed to fusion bonding. [ 21 ]

This "soda glass" is mildly water-soluble, so some calcium carbonate is added to the melt mixture to make the glass insoluble. Bottle and window glass ("soda–lime glass" with transition temperature ~570 °C) is made by melting such mixtures of sodium carbonate, calcium carbonate, and silica sand (silicon dioxide (SiO 2)). When these materials ...
