The ordinary glass is the silicates of sodium ad calcium with excess amount of silica. Na2SiO3.CaSiO3.4SiO2 The basic components of glass are soda lime and sand it means Na2CO3 , CaCO3 and SiO2 the basic reactions for formation of glass are, Na2CO3 + SiO2 = Na2SiO3 + CO2 CaCO3 + SiO2 = CaSiO3 + CO2 Na2SiO3 + CaSiO3 + 4SiO2 ==1400 celsius== Na2SiO3.CaSiO3.4SiO2 Potash glass cotains potassium instead of sodium. pyrex glass is Na2SiO3.CaSiO3.B2(SiO3)3.SiO2

∙ 9y agoThe chemical reaction that happens when making glass is heating. It involves heating oxygen and sand to produce silicon dioxide. When it cools, it hardens into glass.

∙ 13y agothe main raw ingredient for glass is silicon dioxide, from sand. sand produces glass when it melts but the temperature must be 2000 degrees c.

Is breaking glass a physical change?
Yes, as it's still glass. There is no chemical/molecular change.
Is etching glass with acid a chemical or physical change?
It is a physical change caused by chemicals. Chemical changes are phyiscal changes.
Diamonds are used to scratch glass chemical or physical change?
This is a physical change. There is nothing that changes the components of either the diamond or the glass when the diamond is used to scratch glass.
Why is Breaking of glass a physical change?
A physical change can be reversed, for it does not change what the object is made of. The glass, even when broken, is still glass. It can be put back into its original state (possibly through melting) because it never changed what it was made out of.
Is breaking a glass beaker chemical or physical?
Breaking, grinding, cracking are all examples of a physical change. The nature of the substance has not changed, just the size of the pieces has changed.
Is breaking glass chemical or physical?
Breaking glass is a physical change, as it does not change the chemical composition of the material.
Is breaking glass a physical change?
Yes, as it's still glass. There is no chemical/molecular change.
When glass brakes is it a physical change?
A glass breaking is a physical change because the chemical composition of the glass does not change.
Is mixing of glass pieces and sand a chemical change or physical change?
it is a chemical change.
Is hot glass cracking when placed into cold water a chemical or physical change?
It is a physical change because the chemical composition of the glass does not change.
Ice dissolving in a glass of lemonade a physical or chemical change?
its a chemical change
Is etching glass with acid a chemical or physical change?
It is a physical change caused by chemicals. Chemical changes are phyiscal changes.
Is glass a chemical or physical change?
Glass is not a change of any sort. It is a mixture of substances that can undergo both physical and chemical changes
Is ethyl alcohol in a watch glass a physical or chemical change?
Neither. It is a chemical compound, and not a change at all.
Is shattering a glass a chemical or physical change?
Shattered glass is a physical change because the identity of the glass does not change.
Is glass breaking a chemical or physical change and why?
Physical change because before and after breaking a glass, the glass is still SiO2 (Silicon): it's chemical makeup is not changed by the breakage.
Diamonds are used to scratch glass chemical or physical change?
This is a physical change. There is nothing that changes the components of either the diamond or the glass when the diamond is used to scratch glass.
