Oxygen, Meet Silicon – And Let the Glassmaking Begin
Oxygen, Meet Silicon – Let the Glassmaking Begin
Oxides – the chemical compounds that make up glass – represent most fundamental of chemical pairings: at least one oxygen atom with one other element.
And the vast majority of glass compositions depend on an oxide called silica, which bonds two oxygen atoms with one of pure silicon. The combination is a powerful one for many glass compositions, because the more silica a glass contains, the lower its thermal expansion and the higher its resistance to heat shock.
