Iron’s basically everywhere in the real world, too. By mass, it’s the most common element on Earth, making up much of our planet’s outer and inner core. The magnetic field that all that iron generates is the reason why compasses work. So next time your friend screams ‘compasses work because of WITCHCRAFT!!!’ link them to this article and set them straight! Also, get better friends.

On the surface of our planet, there isn’t so much natural pure iron, but there’s a lot of iron ore - which humans only began to be able to take advantage of when they developed the technology to build furnaces capable of reaching 1500C or so - the temperature at which iron melts. This marked the beginning of the Iron Age.

Today, iron is by far the most common industrial metal — often in alloys such as steel — because it’s relatively cheap and abundant, but also strong. The body of an adult human contains about four grams of iron, which is used in various biological processes, meaning that the entire human race contains about 30 million kilograms.

That’s a lot of ingots. More than you can fit into a chest. More than you can fit into a double chest! Maybe it’s time to upgrade your storage room...
