[[Materials]] are produced required to make new items via the [[crafting]] system. They are obtained by recycling [[salvaging]] magical, rare, set, and legendary items in with the [[Salvage CubeBlacksmith]]. Materials are required ingredients in all Blacksmith recipes. There are three types of materials keyed to each difficulty level, and the Normal, Nightmare, and Hell materials can be upgraded to the next difficulty level -- for a price. During much of Diablo III's development, salvaging was handled in the [[Nephalem Cube]] and there were four types of materials per difficulty; the "white" quality materials were removed, along with the ability to salvage normal or cracked item qualities, late in the Diablo III beta. * See the [[materials]] and [[crafting]] recipes, and they have other purposes as well[[salvaging]] articles for full details.
