Re: haunted VDB
Hi Loris,
I don't know any gold plater, i would have to research.
But I do have some gold and I worked with AR before (and a lot) plus
I'll do it in a chemistry lab with fume hoods etc.
Have any of you used a paper called Oxford white?
Best,
Joao

Don't you have any gold plater near/around you? As I said before it
would be
less cheap and I add now: far easier and infinitely less dangerous to
purchase few grams from them instead of dealing with aqua regia!!!

Hi Judy,
I'm not sure it is the plastic as some pictures changed and others
didn't.
I can buy selenium powder here but the cost is hi (higher than silver
nitrate)
Not to start that argument again but I'm planning producing gold
salts using
Lyan's method in PF.
The thing is I like the brown color and gold will shift it to purple
black
isn't it?
Well, trying is part of the game, who knows I might fall in love
when I see
it in my hands.
Thanks,
Joao

I'm wondering if that plastic sleeve the print was stored in was
something you'd used before... There are plastics that simply destroy
photographs. I remember many years ago my mother put all her family
photographs in an album with pages in plastic sleeves, for her
grandchildren... by the time we actually inherited it, just a few
years later, the degradation of the prints was striking -- tho these
were color photos and the chemistry is obviously different.
However, I had some of the same photographs, stored in paper or under
glass, so I could measure how much hers had faded in that relatively
brief time. (If I'd been trying to fade them I couldn't have done
better.)
As for as selenium toner is concerned, if you can get your hands on
some selenium, that is, the plain chemical itself, you can mix up a
selenium toner without the fixer. I don't remember where I got my
selenium (about 28 years ago), tho of course in those days sale of
chemicals was much more loosey goosey than today... it was also
expensive -- but ounce for ounce of the working solution not all that
terrible.. and MUCH more flexible than KRS. (I never did understand
why they put it in fixer-- tho that's not this e-mail.)
The old photo books or formularies should have the formula for
selenium toner, or I could probably dig up that old one. However,
I'm
wondering what's wrong with just plain gold toner?? (Is this a good
or bad time to buy gold chloride ? -- I don't follow that nowadays,
since gum bi just shrugs off gold. But if memory serves, when the
market is down, so is gold? Whichever, per print toned it's not so
horrendous. (You only tone the successes.) Also, as I recall (tho I
haven't used it lately) the color is lovely.
Not to mention -- have you noticed galleries stressing the "gold" in
"gold-toned prints"? (Sounds so much better than "selenium toned.")
