Various Glass Production Processes

Glass Production, one of the most prominent works since centuries has come up to a very varied and vast field in itself. Tempered Glass more referred to by the popular name, safety glass, indeed stands up to its name.
It is almost six times stronger than the normal one and is very safe in comparison too. The latter breaks up into little dangerous edgy pieces while this former breaks up into small oval shaped pebbles which are harmless even if they come in to human contact. There are many ways to make this glass. Along with the processes, it is ensured that quality control is maintained throughout.

Various Glass Production Techniques:
Glass Production is carried out under various techniques. Safety glass is made under high stress conditions and at high temperatures. It is much stronger than the normal type. One thing to be kept in mind while using it is to ensure that there are no cracks or nicks on it, due to which it might break into little pieces all at once, unlike normal glass. When regular glass is used to make safety glass, one has to ensure that the regular glass, after etching and other design, that it is fully flawless, for even if a little crack is there, it is rendered unusable to make safety glass.
To make the glass, ingredients like oxides of either aluminum or magnesium are used, which are also referred to as soda, along with silica and lime. The molten glass is obtained by heating the mixture, of a mentioned proportion, to 1200 degrees C, which renders the glass in a liquid form. This molten glass is then introduced to rapid cooling which is also termed as quenching. Safety glass is subjected to high tensile force and compression so as to get the desired thickness and shape. By heating this mixture over a series of times, the compressive and tensile force is reduced so as to get the strength in the glass as required. The main advantage of this glass is that, in the event of a mishap, to escape, this glass can be broken by a metal object and breaks up into pebbles rendering it harmless.
Ovens used in the heating of the Glass Production process vary in all sorts of shapes and sizes from a small unit to an assembly line that include conveyor belts carrying glasses over it. Different cooling methods of cooling are adapted for the making of the safety glass. In earlier times, sand and brine were used for cooling. Instead, recently cold air jets are used to cool the glass rapidly. The use of these air jets renders the cost of production very low. When compared to laminated glass, this type of method is much economical.
After the Glass Production process, the safety glass undergoes various tests and quality checks. Even if the latter fails in one test alone, it is not accepted. Any product requiring use of strong glass uses this glass, which also includes windows and automobiles.
