Smelting – Minecraft Wiki
3 天之前 Smelting is a method of obtaining refined goods from raw materials by heating in a furnace, blast furnace, smoker or campfire. For example, raw iron can be smelted to produce iron ingots using coal as fuel. Like crafting, smelting uses recipes to determine what item is produced, but its recipes are simpler. Smelting also yields experience. The
