How pure do we need Silver Nitrate?

How to do determine best value?

How is it best stored and how long will it last stored?

Are we allowed to to name sources?

DEA regulation?

How pure do we need Silver Nitrate?

Which uses do you have in mind?

Are we allowed to to name sources?

Yes.

Salt prints. Denise Ross film and glass plate emulsions as posted on her website.

Right now I only know of 2 sources. Photograghy Forumlary and a Salt Lake City firm.

I have bought from PF for years. Good products.

Pricing varies. Purity is not clearly defined by 'recipes' or vendor.

This stuff is so expensive I don't want to make mistakes in sourcing.

I do know I will make lots of mistakes learning the processes. That's where the fun is.

Which uses do you have in mind?



Yes.

I have always gotten it from Bostick and Sullivan: Silver Nitrate Reagent Grade

Price depends on the amount; currrent prices on their website are from $1.35 down to $1.10 per gram. However, in the past there was a limit that they could mail without extra (hazardous material) shipping charges. We never needed too much at a time, so generally it was not a problem...perhaps 25 grams. But it has been several years...used for salt prints.

OK I ordered some. PF made me sign a DEA form for 10 grams. http://www.saltlakemetals.com/ did not. I find that odd!

Googled Reagent Grade and found this https://www.spectrumchemical.com/OA_...0&respid=22372 Lot's of data, but what do I use?

Still confused, I suppose the 10 grams from PF will work and the http://www.saltlakemetals.com/Silver_Nitrate.htm is a test.

I have dragged my feet too long on doing these processes and have nearly everything needed, except that Cheese jar Denise recommends for emulsion noodles. Can't find the once common cheese...

I forget them. Never used them.

Their pricing is way cheaper. But they don't specify grade, purity,...http://www.artcraftchemicals.com/pro...-part-ag100-3/

Randy, you might also try posting your original question on APUG. Ron Mowrey and Denise Ross are both active on that forum, I don't think Ron's here and don't know whether Denise is or not.

They have another listing that specifies ACS grade. It's Part #1770. 1765 and 1760 are the same in smaller quantities.
