Can glass burn and catch fire?

Glass is melted sand so it is already "burnt". In a fire glass will shatter, soften and then "carbonise" = turn black and hard.

Just a random thing that i dont know!

Glass is made mostly from Silicon Dioxide (sand). This is already fully oxidised and so can't burn any further.

As there is no carbon in glass it cannot carbonise, which involves heating organic matter such as wood in an oxygen deficient atmosphere. Any blackening is due to soot deposition from other sources.

For something to burn or combust it must be able to react with oxygen in the atmosphere.

Silicon like carbon can only have 4 covalent bonds. In glass, which is silicon dioxide, silicon is bonded to two oxygen atoms. Both of the bonds to the oxygen atoms are double covalent bonds. This means that silicon can not react further with oxygen because its valence electron shell is already full. Further, the silicon atom in silicon dioxide is also fully oxidised already by virtue of it being being bonded to two oxygen atoms.

Silicon oxygen bonds are extremely stable which is one of the reasons why glass is so unreactive and which is one reason why it makes great containers to do chemical reactions in. Glass does however react with one particular element, but it will not burn in the conventional sense of the word (combustion/reaction with oxygen). The element I speak of is fluorine or compounds derived from fluorine. Hydrofluoric acid, HF, is extremely reactive and will dissolve glass. HF is used industrially to etch glass.

Doesn't burn Melts and breaks due to heat and carbonises in house fire doesn't burn

It means ignorant people who believe in rather silly claimed magical gods shouldn't make their giant god-man statues with metal frames...that act like lightning rods. If they'd gone to science/engineering class instead of screaming about how evil science is, their magic jesus statue might still be standing...or perhaps they never would have built it in the first place ? Peace.

If a flame catches the glass, then it will just turn black

It is possible to burn glass in an environment of fluorine gas. I've never seen it, but it sounds pretty cool.

because of the properties of glass it melts but it doesnt catch fire.
