Quartz crystals and silica sand have very high melting points, and safety precautions must be taken when melting the mineral at home. When exposed to extreme heat, the quartz or silica sand creates molten glass, which can then be reshaped before it re-hardens.
There are still many things to learn and know when you melt glass at home and create glass art. Bottles can be melted by draping which is letting the weight of melted glass shape over a mold at 1200 F. Glass marbles can be melted until they stick together using the tack fusing method at 1350 F. Crushed pieces can be placed inside a mold by frit casting at 1480 F.How to Melt Glass With a Torch | SciencingOct 19, 2017 · How to Melt Glass With a Torch.
