I believe melting most items is a physical change as you are only changing the state of the matter, not it's composition. There may however be a breakdown that occurs depending on the composition of the glass with high enough temperatures. This would change the chemical composition.
I believe you can relate it to melting plastic (don't actually do this as it releases toxic gases). At low enough temperatures it just becomes soft and moldable. At higher temperatures you burn it down and cause changes in the material.
I'm no expert
Melting glass is a physical change. (A chemical change would need chemicals or other ingredients to be added to the molten glass.)
I think it is a chemical change
no- melting is not a chemical change. It is merely a change in state of the same substance not a chemical reaction.

physical change according to physics nd chemical change according to chemistry
Melting is a physical process.

A physical change can be reversed, for it does not change what the object is made of. The glass, even when broken, is still glass. It can be put back into its original state (possibly through melting) because it never changed what it was made out of.
