Base Metals Mod adds historically common metals to Minecraft, specifically silver, copper, tin, lead, zinc, mercury, and nickel, as well as the fantasy metals cold-iron, mithril, adamantine, and star-steel. For most of these metals, you can craft all of the standard Minecraft tools and metal-related blocks. Base Metals also adds a new tool, the crack hammer (aka sledgehammer). The crack hammer lets you pulverize ores and items into powders. Just like the Crusher in the Metallurgy 3 mod, pulverizing an ore block with the crack hammer will double your metal production.
