Solid Ash

How is it possible that the glass is made ​​from solid materials in color and still see her through?

I thought .. I know glass is made ​​of limestone, sand, soda .... etc., they are all colored so how does the glass turned out to be colorless? what kind of colors / he waves reflect or absorb? If possible then is it possible to see through the paint, clothes and objects?

Materials such as flat glass or crystal glass are transparent because they allow much of the light that falls on them to pass with little to be taken into account. The glass does not have the color of its original features such as sand, soda ash etc. is because of how its elements is deposited or re-organizes they combine to form molten glass. Some glasses are not completely transparent, green glass, such examples reflect green etc. light of other materials which are transparent are: 1. varnish, which is a type of see through the paint 2. polyurethane, which was known to be transformed see through clothing, chairs and inflatable beach. 3. clear plastic containers you can find in the kitchen
