The simplist plain glass requires sand, soda ash, and limestone. For some example recipes go here

The soda ash lowers the melting point (fluxes) the quartz in the sand from 3100F while the limestone stabilizes the mix which with only soda ash will be corroded by water. Other ingredients reduce color and help get bubbles out of mix.
A typical recipe is cooked at about 2400F for 4-8 hours and then reduced to 2000-2100F for use.

Try looking into Alfred University in Alfred, N.Y.- they are a top ceramics school in the country, and also have a glass-making course and glass -making curriculum, I believe. Small school, big focus.
