Iron Anvil

3x Iron Block, 3x Iron Ingot, and 1x Copper Anvil

An Iron Anvil is made by upgrading a Copper Anvil in a crafting table. It is used to make Steel Ingots.

Durability

Just like vanilla, anvils have durability. When an Iron Anvil breaks, it reverts back to a Copper Anvil and will have to be upgraded again.
