Hi guys, found a 20-30% mix and it appears to have done the trick over an hour or so. I have plenty of shining up to do but the worst is off. Thanks very much for everyone's advice here and I'll update my blog with photos and post here as piece get done so you can see the result.

I still intend to case color harden these parts now that I am on a mission. I'm having an air tight stainless steel container made so that the charcoal mix and parts don't get contaminated.

Cheers
