Volcanic glass or obsidian maybe gave someone the idea. Or, maybe, the nodules of glass that can form when lighting goes to ground through sand. In any event, glass is made by â¦ heating sand until it melts. Actually, the sand particles have to be separated first. If you just melted sand you would get a dark, non-transparent glass. You have to find the clear crystals in the sand to make glass. It is then melted and either blown or molded into the desiered shape. Glass was probably discovered after a volcanic eruption near a beach. Glass was first created by the Phoenicians and the Egyptians.
