The glass industry has instituted a numberof regulations, or standards, that govern the process of making glass and thefinal requirements for each type of glass. Quality control testing is performedto ensure public safety for products that include glass as one of the materialsused in their manufacturing. An example is found in the automobile industry;tempered glass must be used for side and rear windows.If an accident were to occur,the tempered glass can be broken with a metal object and allow the passengers to escapeor allow emergency teams to reach the passengers trapped in the car. One of therequirements tempered glass must meet is that it must remain intact at 10,000psi (pounds per square inch); most tempered glass can remain intact at 20,000psi or more.Glass is made from any of a number ofmaterials, including aluminum or magnesium oxides, silica and lime. The rawmaterials are heated to their melting point, shaped and then cooled. Often themolten glass is plunged into cold water to cool it quickly and retain itsshape.Tempered, or annealed, glass is up to sixtimes stronger than regular glass. Because of the inherent breaking pattern,however, it must be cut to shape before the tempering process. Regular glass iseasily cut, but theres a high probability that if tempered glass is cut, thestress from the cut could reduce it to a pile of rubble. After the regularglass is cut to size and shape, which includes edging or decorative etching, itis inspected for any imperfections. Any flaw in the glass makes it unsuitablefor creating tempered glass.The glass is heated to over 1200° F (650°C) and then cooled rapidly. The process of rapid cooling is called quenching. Itnot only solidifies the molten glass to help it retain its shape, but makes theglass stronger as well. Using the combination of compressive and tensile stressis how tempered, or annealed, glass is made. A compressive stress is when theoutside of the glass object is cooled quickly. The inside is still relativelyhot and cools more slowly, creating tensile stress. Each time the heating andcooling process is repeated more stresses are eliminated, resulting in strongerglass.The ovens used to create tempered glass canbe small units to accommodate single panes of glass up to huge, conveyer-beltovens that continuously run products through the oven. The most cost-effectivemethod to quench tempered glass is cold air jets. The jets are placed in closeproximity to the glass and blow very cold air on the glass. The use of cold airjets instead of previously used methods, like oil or salt brine, keep the costof tempered glass production down and make it much more affordable than laminatedglass.After the manufacturing process iscomplete, the glass is tested to verify it conforms to all applicablestandards. Any products that do not meet standards are rejected. Tempered glassis the norm for many end products like automobiles, building windows andvirtually any product that weaker glass may be unsuitable for.More than one inventor has taken the creditfor tempered glass. About 1750, Francois Royer de la Bastie claimed to inventtempered glass. Then, around 1935, Austrian-born Rudolph Seiden was granted thefirst patent for tempered glass in the United States.
