Tannic Acid and Ferric nitrate interaction with metal inlays?
« on: January 11, 2019, 08:14:46 AM »
Is there anything I need to know about applying these chemicals with the brass and steel inlays?  what happens with respect to neutralization?

It will discolor inlays but cleans up with a little steel wool. No discoloration of surrounding wood.

Say, any of you boys smithies? Or, if not smithies per se, were you otherwise trained in the metallurgic arts before straitened circumstances forced you into a life of aimless wanderin'?

Yup!

After the acid and FN and the blushing, you will be burnishing the wood hard anyway, and in that process, removing any oxidation that the fluids cause, down to bright metal again.

it will give your brass and NS something of an "aged" look.  It won't turn it black if that's what you're asking.  It doesn't seem to affect sterling nearly as much.  I liked the aged look so just left it, as, I really don't care for highly polished and shiny metal.

A wet paper towel will get off a lot of the residue.  So will ammonia used to neutralize.  A light gray Scotchbrite pad will take care of the rest.   I go over the whole stock with a Scotchbrite pad anyway.   I remove iron/steel parts after staining for final polishing before blueing or browning; so, I don't worry about those.
