The Cleaning of Blades

Rick · 19th May 2018, 02:32 PM

When I'm finally finished with the rust treatment I'll post the blade before I try an etch with super strong coffee. Right now the blade is in a heavy coating of De-corroder wrapped in plastic wrap to keep it from drying out too quickly.

Something occurred to me about the subject under discussion: there are many variations in quality of steel and pamor material; would this difference not interfere with a consistent result in whatever rust treatment is involved?

/5/20

Well, here are pictures of this blade after treatment with Metal De-corroder (a Renaissance product) a hot rinse and before any etching has been attempted.

It was quite crusty and the color difference was not aparrent; no before pics, sorry.

Would be interesting to see your post-etching results, Rick.

Yes it would; if I had anything that could produce a warangan type of etch.

I'm reasonably happy just to see a contrast between the metals; the EPA doesn't want me to possess arsenic trioxide.

Though i do believe you said you were going to try a solution of strong coffee, though perhaps "etch" is not the correct word for such a bath. At least i hope not since i am bathing my stomach in some pretty strong coffee right now. LOL!

I bought a small jar of instant and made a paste, applied it to the blade and all that happened was an increase in contrast between the pamor and the core.

Not really worth belaboring the board with another tombak picture..

Hello everyone

The only way to remove the oxide is the electrolysis and the zinc-soda method, without attacking the base metal (iron or steel). It is the method used in the museums (besides the ultra-sound) and in the objects recovered from the sea
