Glowing Ingots

Glowing Ingots are made by processing normal ingots in an Heat Treating Oven. When having Glowing Ingots in your inventory they'll keep setting you on fire if you don't have any Blacksmith's Tongs in your quickbar/hotbar. To cool them back down, that means converting them back into normal ingots, simply rightclick them onto a cauldron with some water. Since when the metal is glowing you can't tell the difference by the image at all there always is a small letter, written in the colors of the metal, in the top-left corner of the image. E.g. In the picture at the left someone is cooling down some glowing gold(notice the golden, hardly recognizable G in the top-left).
