Inside our daily life rather to see the usage of glass in its different forms, transparencies and qualities. We come across them in the windows on the houses, we come across ourselves within a mirror at the outset of the day, picking out a drink within a bottle, in thin eyeglasses, and the kids play with projectiles made of glass (marbles) between the different ways in which we can see them.

The glass is a mixture of various substances obtained by simply melting around 1500 ° C silica sand (SiO2), sodium carbonate (Na2CO3) and limestone (CaCO3) in different ratios, which many used certainly is the sand silica.

Without collecting in the chemical substance terms and although I am unable to believe it as a child, glass is made with fine sand, and that is high is an element called silica, which is the key basis for making glass. Additional substances can also be needed, that will depend on the last use which is given to the glass.

Once all the substances are jointly, the glass manufacturers generate the combination, until they will form a paste that they can pour to a container called a crucible, which is very resistant to heat.

The crucible is put in an the oven at extremely high temperatures, which causes the impurities to evaporate and all the constituents are mixed well. When the mixture touches and becomes liquid, then this glass is.

When you have that, you give it the design it takes, say, to make bottles, Chicago Glass Company have a hollow material tube make one result in the molten glass concoction and get a small ball, let it refreshing seconds and commence to strike hard on the other end, building a ball, as when you make soap bubbles, only this time utilizing a mold and continue blowing until it will take the desired condition.

The crystals formed inside the glass cause it to lose visibility and customize other real estate. In contemporary sodium and lime glass, part or all of the lime can be substituted by different alkaline ground oxides and part or maybe the whole of sodium with K2O. Salt and lime scale glass can be used to produce bed sheets, plates, storage containers, light bulbs and various gadgets.


Glass is a entirely recyclable material and there is no limit towards the number of times it can be reprocessed. When recycling it, the properties are not lost and an amount of energy of about 30% is usually saved in comparison to the new glass.
