Rust toner

[seanE]

Has any one ever toned a print with iron oxide ''scraping the rust of an old horse box'' powdering and diluting with water, then painting on a print.:munch:
''i recon it might go well with the prints from my hillbilly enlarger''

It would probably work, but you'll have to spray it with WD40 so as to halt the rust from advancing further. Oh, and don't let people view the print to close or the smell might give up your unique technique! John W

Rust never sleeps .

Never thought of this one. You might get similar results from using tea or coffee. Plus they might soak into the print better.

off its fb print, no need to soak
abraded the print surface with the finest sandpaper you can find
take the pulverized rust dust and rub it onto the print
it works well with graphite dust ( from sharpened retouching leads)
it might work well with rust ...
old paper surfaces might work best
some has a "tooth" and we're meant to be retouched and toned with hand work.
hand coated home made prints would work too ( hand coated with liquid or home made emulsion
or cyanotypes/or other alt/pro stuffs )
have fun !

Wouldn't the rust eventually bleach the silver in these rust toned prints? Has anyone ever tried this?

Yer, coffee sounds good to, And il remember to bring sand paper in the dark room when I'm trying it There is a thing ''excuse my unscientific language'' Where two different metals meet, There is a reaction that results in corrosion as far as I'm aware, So only time will tell if it would bleach it, That might explain why they use precious metals as toners.

This is not about two metals meeting, it's about a strongly oxidized metal meeting another one in its reduced state. And strongly oxidized Iron (Fe3+) is known to oxidise Silver (c.f. Ferric EDTA, Ferric PDTA and Ferricyanide bleaches).

hi rudeofus

do you think rubbing rust into a print would so something like "silver it out" ?

i've been trying to figure out how to do that for years ! ...

I don't know the full mechanism behind "silvering out", but in this thread a gentleman claims that it happens when unfixed silver reacts with Hydrogen Sulfide. Rust would likely react with metallic silver to form some silver salt, which would then react with aerial contaminations over time. Not sure how uniform or repeatable this process would be, though.
