Believe it or not, glass is made from liquid sand. You can make glass by heating ordinary sand (which is mostly made of silicon dioxide) until it melts and turns into a liquid. You won’t find that happening on your local beach: sand melts at the incredibly high temperature of 1700°C (3090°F)

- CaO – Calcium oxide from Limestone / Dolomite.
- MgO – Dolomite.
- Al2O3 – Feldspar.
