## How to Smelt Iron: The 6 Steps to Iron Smelting

Iron ore can be bought or gathered, but for the sake of demonstration, we gathered the ore ourselves. The best time to collect iron ore is in the winter because the ocean is more active. Active waves separate the black, magnetic sand from lighter silica sand. This magnetic sand is an iron ore called magnetite, which when combined with carbon, creates iron. As you might imagine, iron ore is heavy, so
