Iron

Iron is a hard, durable material used to craft many tools, weapons, and also used in construction. Iron requires higher temperatures to be smelted compared to copper or bronze and so must be produced in specialized furnaces called bloomeries. The main advantage of iron over bronze is that Iron Ore is much more abundant than Tin Ore. Iron, like other metals, does not decay. Smelted iron has a silvery-grey color, as compared to the rust-orange hue of its unprocessed ore.

The discovery of iron smelting technology initiates the Iron Age.
