The Crucible is most in danger of melting down at the end of an operation when all the materials have been poured out and fuel is still burning. Some materials can be used as moderators to limit the risk of destroying the Crucible. A Gold Ingot has very high mass and high boiling point, so it will often absorb enough heat to protect the Crucible. If there is any Copper in the Crucible, Lead can be used instead, otherwise the Gold and Copper could alloy to form Rose Gold.
