Have you ever accidentally made a colored wool when you didn't mean to? You say "I'm going to make 10," but you make 11? Well, with this, putting iron and light gray wool into the crafting table will make steel wool. Putting steel wool in the crafting table with colored wool will turn it into white wool (or right clicking on a colored wool block). It will not drop the dye, and will restore it to either white or light gray, depending on what the color of the colored wool was.
