Copper Ore is a block added by Tinkers' Construct. It can be mined with a Stone Pickaxe and smelted in a Smeltery to produce two Copper Ingots. Alternatively, for less copper, you are able to cook Copper Ore in a furnace. Copper is used in many things throughout the Tinker's Construct Mod. It can be made into a copper block if you have 9 copper ingots and 1 copper ingot can be breaked down into 9 copper nuggets.
