Glass does not typically "break" at any temperature. If you want to be technical, the melting point of glass is 2600-2900 °F.
Now, another important and relevant fact is that when things are hot, they grow very slightly larger due to their molecular composition. When something is very hot and is suddenly made much cooler, it will quickly shrink back to normal. When fragile things like glass are cooled down too fast, the shape change is enough to crack or break them.
