Technically, Glass is a liquid. It is considered to be hard and therefore brittle. Cast iron is considered to be hard and brittle and it breaks readily if too much stress is applied to it.
If we heat up glass we can blow the glass and form various shapes and usable objects. Glass has to be tempered to remove the cracks from it.
I have broken a plain glass pane in two and then with heat joined the broken panes of glass back together with no raised edges where the glass planes were joined together because of misalignment.
The glass in doors and windows today is safety Glass which is laminated with a plastic sheet between two thin panes of glass, just like a windscreen in a car. It is more difficult to cut than ordinary glass because of the plastic films that are used to make the laminated glass panes.
Glass can be bent by applying heat. One method is to heat the glass pane up and to then allow the glass to take the shape of the mould, in an oven.
Technically, glass does not bend but breaks. Laminated Glass can take a lot more stress when being bent before it will fail and break.
