    Default Melting Bronze in open air crucible versus silver...

    I'm using a handheld butane torch (welders) and crucible for melting metals (for molds) in open air. I have a curious question about melting bronze versus silver.

    According to the attached chart, bronze has a similar - actually slightly lesser - melting point than silver.

    However, I am able to easily melt silver to liquid for pouring (using the torch and crucible)...and yet I can't melt bronze to pouring.

    I may need to build a melting furnace. But...

    Can anyone tell me why this would be the case?

    Thanks!
