Can you melt glass in oven?
Glass has a melting temperature of around 1400-1600°C (see here ), and most household ovens top out at around 200-250°C so no, you cannot melt glass in a normal home oven.

Does heating up glass weaken it?
Hot temperatures can cause the glass to break when the bottle is subject to excessive thermal variations. On the other hand, if a glass container is placed on a very hot source of heat (500°C for example), it can gradually lose its shape and change from a permanent solid form to a plastic state.
How do you heat up glass without breaking it?
To prevent the glass from breaking, you can also boil the glass in water for 10 minutes. When the glass is evenly heated, it will not produce strong pressure, nor will it cause the cup to break, or you can rinse the cup with a little hot water before filling it, and then blow it up when pouring hot water..

Why would you heat glass?
Heat Polishing Glass When you heat glass to a temperature of 1300 to 1350 degrees F, the surface of the glass becomes soft enough to just start to melt. By heating to a point where just the very surface of the glass reaches this temperature, you can produce a smooth, shiny effect.
