2, namely quartzy, the main component of sand).And pure silicon soil fusing point is 2000 degree Celsius, generally can add sodium carbonate (Na when therefore making glass
2CO
3, i.e. soda) with potash (K
2CO
3, potash), the tripoli fusing point will be down to about 1000 degree Celsius like this.But sodium carbonate can make glass soluble in water, therefore also will add an amount of calcium oxide (CaO) usually and make glass water insoluble.
