Copper Ore

Copper is one of the first minerals you find when starting a new world. It is commonly found in caves and sometimes at the surface. Better than Stone, worse than Tin, it is perfect for your first set of tools or armour.

Mineral veins
Copper Ore spawns below y-90 and its maximum vein size is 7.

Obtaining
When mined it with at least an stone-level pickaxe, copper ore will drop itself. If mined by any other tool, it will drop nothing.

Usage
Copper ore can be smelted into copper ingots, which have mostly technical and generic uses, or it can be smashed and combined with tin dust to create Bronze Dust, integral in crafting bronze. Crafting visuals of smelting copper ore (along crushing it into dust for bronze dust) would be appreciated.
