being new to this I can't say, some doesn't seem to be excessive. I understand scale is a product of decarbonization. I further ,If I understood what I was reading that it is a byproduct of excess heat among other things that I cannot control. is this correct?
fe3o4 is iron oxide , no? The decarbonization thing was from googling decarbonization. I heard the term so I googled it. They said it was a by product of several factors 1 being excess heat, I have not forged anything but hi carbon, spring steel. I place the work level center of fire cone then cover with material , add air wait until the fire glows yellow turn off the air and most times it is bright orange once it was bordering on yellow but looked to be too hot. Unless I wanted to weld. I'm not up to welding yet, I'm getting the hang of moving the steel the way I want it to go.I have been watching tube videos and of course forged in fire, getting the way to work the metal from those sources.
