Hammered Out Bits: Ores for Bloomery Iron Smelting?

Jan 05, 2014 · Hematite Grit is tricky to use in our bloomery furnaces, as the smaller size particles tend to reduce quickly and absorb excess carbon. This can yield 'steely' blooms - but its also easy to end up running too hot and getting cast iron. Fine Iron Oxide Pigment is used in two modern applications. It comes in 50 lb bags, used for glazes by potters ...
