coltpax Posted August 2, 2008 Posted August 2, 2008 Does anyone know what the scale that comes off of metal is made up of? Just thought about that last night, and I figured I would ask you guys. Quote
nett Posted August 2, 2008 Posted August 2, 2008 Iron oxide. It's still magnetic so it's easy to collect and is the same material they used the Fuzzy Face Quote
Bentiron1946 Posted August 2, 2008 Posted August 2, 2008 I've heard it called super rust or super scale because it forms so fast in the fire. Some wire brush it all off and others leave it on and oil it so it protects the metal better but I don't know if that is true. Quote
metalliferous Posted August 3, 2008 Posted August 3, 2008 It's iron oxide, and I think it's mostly magnetite (Fe3O4) as opposed to rust (Fe2O3), which gives it the ferromagnetism nett was talking about. Quote
