Glass is a general term in chemistry and the physical sciences used to refer to a substance which has not had time to crystallise befor it's temperature has fell below it's melting point. For example silicate glass's used in windows but a better example would be caramel-to make heat sugar until it melts (there will be some charring) and allow the melt to cool-the high viscosity prevents crystallisation and a solid glass is formed.

The solution for glass:
Glass is a combination of sand, flint, spar, or some other silicious substances, with one or other of the fixed alkalies, and in some cases with a metallic oxide. Of the alkalies, soda is commonly preferred; and of the silicious substances, white sand is most in repute at present, as it requires no preparation for coarse goods, while mere washing in water is sufficient for those of a finer quality. The metallic oxide usually employed, is litharge, or some other preparation of lead. Iron is used in bottle-glass.
I got this stuff off of http://www.publicbookshelf.com/public_html/The_Household_Cyclopedia_of_General_Information/howtomak_cge.html
Look at the website there's a lot of info!

You take silica sand and sodium carbonate, heat it up to a really high temperature like over 1000C and let it melt. Then you can shape it into whatever you want to make. You may need a grown-up to help you with this, it can make a mess of the stove.

No idea, but I heard recently in my Chemistry lesson it involves sand, but I'm not sure of the fll details.. check on google or ask.com
good luck!

Sand (silicon dioxide)+ heat = glass
add a transition element oxide, e.g. strontium or copper and you'll get coloured glass.
