We just learned about Sponge Iron made in a bloomery.
Sponge iron is then turned into wrought iron.
After the sponge iron is made, it has a bunch of holes in it and is very messy.
A blacksmith can take the sponge iron, hammer it a lot, reheat it and keep hammering away at it to get it in better shape, and that is called wrought iron.
When it is all finished, the iron looks nicer and is easier to work with and shape.
