Varnishing is the final step in the wet plate collodion process. Its used on tintypes, ambrotypes and glass plate negatives.
Strand's formula for surfacing prints was reproduced in Ansel Adams' The Print(1950): "First, one buys a small can of lithographer's varnish No. 1...This should last for years. Next one buys a bottle of Carbona (carbon tetrachloride), the solvent for the varnish...A good way to get the varnish into the Carbona is with a swab stick, letting it run off drop by drop until the Carbona is a lemon-yellow color after shaking. The varnish is then ready to apply with a piece of cotton. Cover the print thoroughly...then smooth the whole surface out by taking almost all the varnish off by rubbing briskly with a piece of dry absorbent cotton...The varnish is slow-drying (3 or 4 days)...and I have never noticed any evidence of discoloration." Adams noted "This print varnish is for matte, semimatte, and semigloss prints."
Sorry, I haven't seen the video in years. I was under the impression that most of her series "What Remains" was shot using the wet plate collodion process.That's interesting, but she's not coating/varnishing a wet plate negative. That's a paper print she's coating in that video... and a rather big one - at least one meter across the longer side, if not bigger.
But, I do admit that my knowledge of darkroom procedures and processes is rather basic. That's why I'm asking - what she's doing there is a complete mystery to me. Toning? The toners I've seen and used so far are more or less liquid. She's using something more like molasses - the substance is almost waxy
Varnishing is quite possible, judging from the consistency of the substance. But, I've never heard of varninghing a (paper) print. Toning - yes; but varnishing?
Could anyone provide some insight into the purpose of this procedure (on paper prints)?

Someone mentioned that her exhibit included huge inkjet prints from scans of her ambrotypes/tintypes. I haven't attended one of her exhibits so I can't say for sure. But I do see some of her prints labeled silver gel and varnish so it very well could be glass plate negatives were used or digital negatives from scans of her plates.
...then you might enjoy watching a short segment in the BBC "Genius of Photography" doc, last of the series, showing her working with the collodion process, you should be able to find it on youtube I expect.Since I'm self-taught in photography (and particular in darkroom work), I find it fascinating when I'm able to see what (and how) other people work...
