Chemicals
I can supply many raw chemicals used in historic photographic processes. My silver nitrate price is one of the most competitive in the world. Additionally I can supply kits for cyanotype, Van Dyke Brown, gum bichromate and wetplate collodion. Please email me for further information.

Re: Chemicals
Hi John,
Can you answer a question about silver nitrate?
Does it go "off" with age? I have a tub containing about 200g of silver nitrate that I got about 33 years ago (I know where I was when I got it!). It isn't sealed, but is in its original air tight container as supplied, and is still crystalline.
Thanks,
Susie

Re: Chemicals
Im sure it will be fine Susie although where I buy mine it has a 'best before date' of 5ish years. What are you going to use it for? just out of interest can you remember what you paid for it? Just know I'm gonna weep
