I would say it's scaling in the forge, it doesn't matter if I'm using flux or not. As soon as I take it from the fire and hammer on it, large chunks of scale start flying off.

When you say richer, I'm guessing you mean more gas less air. I'll have to play with it to see if I can get the right combo of air to gas to still get welding heat but without the dragonsbreath 2 feet out of the forge.
