The glass is a combination of various substances obtained simply by melting at about 1500 ° C silica sand (SiO2), sodium carbonate (Na2CO3) and limestone (CaCO3) in different proportions, which many used is a sand silica.

Without collecting in the chemical terms and although I can not believe this as a child, glass is made with fine sand, and that is high is an element called silica, which is the main basis in making glass. Various other substances are also needed, that depends on the final use that is given to the glass.

When all the chemicals are jointly, the glass manufacturers generate the combination, until that they form a paste that they pour into a container called a crucible, which can be very immune to heat.

The crucible is positioned in an the oven at very good temperatures, that causes the pollutants to escape and all the components are mixed well. When the mixture touches and turns into liquid, then glass is.

When you have it, you give it the shape it takes, say, to make wine bottles, Chicago Glass Manufacturing take a hollow steel tube make one result in the molten glass blend and get a small ball, let it amazing seconds and begin to whack hard in the other end, building a ball, as when you make soap bubbles, just this time using a mold and continue blowing until it takes the desired form.

The deposits formed inside the glass cause it to lose visibility and get a new other homes. In contemporary sodium and lime glass, part or perhaps all of the lime green can be replaced by different alkaline earth oxides and part and also the whole of sodium with K2O. Sodium and calcium glass is used to produce bedding, plates, storage containers, light bulbs and various units.
