I have gotten reports of some smeltery recipes (melting and casting) don't work with Thermal Foundation metals.

Cazadorsniper/PO3#1088

it work just fine for me 🤔 granted some stuff can't be melt but i think it's because the temperature of enderium is too hot.(won't work with lava, need something hotter)

i could add blazing pyrotheum as a smeltery fluid like plustic did.

will look into it but i think i already fixed that in dev
