Tin Ore

Tin Ore naturally spawns as an alternative to the Copper Ore in some worlds. Tin ore can be crafted into Tin Bars. Each bar requires 3 ore. The bars can then be used to create tin tools and armor, amongst other things. As all the other replacement ores, it is identical to copper, except for its appearance. Even if the world is tin rather than copper, the player will always start out with copper tools.
