Changes

* The smelting pot is used to smelt metal. You can get rid of spare tools that you've created to grind skill by smelting it back down into lumps. You must use the smelting pot as you would a tool, by activating it and right clicking on the tool you wish to smelt. The item you want to smelt must be glowing from the heat. Keep in mind that if your tool is not large enough to smelt into a lump, the smelted tool will simply vanish.

* The smelting pot cannot smelt every metal item, for instance it cannot smelt locks or keys. And it can't smelt "Newbie" items (the ones you get at game start and won't lose, can't upgrade).
