[TheForge] oil/wax finish, blackened steel

[mike shpeley]

Jerry;
You are more than likely right on the carbon not causing rust as now that I 
think of it a lot higher carbon leaf spring left outside does not seem to rust 
pit any deeper than mild steel. So it has to be the oxygen that causes the iron 
to want to die and go back to where it came from. Another damn assumption. Salt 
in 

the air and water have to be to blame also.

I'm sure I'll be corrected by someone who knows more but I THINK Yellin 
prefered to paint his iron regularly, if the customer wasn't willing to do 
it him/erself would contract it done.

Carbon in steel isn't what causes rust. The silica inclusions offer some 
protection but not a lot. I have an old anchor I pulled out of Anton Larson 
Bay on the north side of Kodiak Isle. some decades ago that shows the 
classic wrought iron rust pattern.

I do agree with not wanting to slather a thick layer of goop over fine 
detail work and would prefer if everybody who bought my work would keep it 
indoors. My favorite, to date, paint finish is clear 2pt epoxy thinned with 
xylene so it makes for a really thin coat. It's tough as nails and doesn't 
hide details. I rub raw wool on my doffers for the lanolin finish and it's 
surprisingly durable though they're indoor items. Deb's a spinner which 
makes us a steelwool couple.
