Useful Tips for using ingot molds:

1: Heat the graphite mold to 250c-500c to avoid any damages in the process and for a higher quality result.
Heating temperatures may vary for different materials.
2: Place scrap into graphite crucible, heat graphite crucible until metal reaches a liquefied state.
Pour molted metal into the pre-heated mold.
3: The graphite molds will last several pours depending on temperatures and types of metal that you are casing.
4: If you run into a releasing problem, you may freeze the mold to allow the ingot to release.
