How is the glass? Why

Our daily life is common to see the use of glass in its various forms, transparency and quality. We see in the windows of the houses we see in a mirror to start the day, to buy a drink in a bottle, fine drinks, and children play with balls made of glass (marbles) in different ways we can find.

The glass is a mixture of various substances obtained by melting at about 1,500 ° C of silica sand (SiO2), sodium carbonate (Na2CO3) and limestone (CaCO3) in different proportions, the one most used is the silica sand.

Without gather in chemical terms, and although I believe it cost Small, glass sand is , is that there exists an element called silica, which is the primary basis for preparing the glass. Also need other substances, that will depend on the end use will give the glass.

Once all boards are substances, glass manufacturers produce the mixture to form a paste discharging into a container called the crucible, which is very resistant to heat.

The crucible is placed in an oven at very high temperatures, which cause the impurities to evaporate and mix all the components. When the mixture is melted and becomes liquid, then formed glass.

When they have, given the form it takes, say, bottles workers to take a hollow metal tube and put one end in the mixture of molten glass and take a small ball, the left cool a few seconds and begin to blow strongly from the other end, forming a sphere, as when you make soap bubbles, only this time using a mold and continue blowing until he takes the desired shape.

The crystals formed in the glass make you lose transparency and alter the other properties. In the modern glass and lime soda, lime or part of the whole can be replaced by other alkaline earth oxides and part or all of sodium K2O. Glass soda and lime is used to produce sheets, plates, containers, light bulbs and appliances diverse. Recycling

Glass is completely recyclable material and no limit on the number of times it can be reprocessed. To recycle the properties are not lost and saved a lot of energy around 30% over new glass. Here

have a couple of videos of the process by which glass is produced so industrialized.
