The melting point of aluminum is 933.47 Kelvin, 660.32 degrees Celsius, or 1220.58 degrees Fahrenheit.

Aluminum does work well for many glass related applications but press molds would have to be water or air cooled and certainly not the best solution for long term use. That said how many molten gathers have I stuck into aluminum optic molds? literally thousands upon thousands.
