Only a few chemicals used in photography are found in a grocery, hardware or
drug store.
Two US suppliers of chemicals are www.thechemistrystore.com and
www.techcheminc.com. The chemistry store sells many chemicals used in
photography but their main focus is on making soaps and lotions. They sell
hypo, triethanolamine, glycols, sequestering agents, ... Techcheminc sells a
full range of photo chemicals like developings agents. The two sites somewhat
complement each other.

Subject: [pure-silver] Acquiring photo grade chemicals
Hello all,
We've been discussing chemicals for the past while and it brings to mind a
problem that we as group, pure silver photographers who live and die with the
chemicals they use are facing... I don't know about the situation in the US
and the UK, but in Canada, it is getting harder and harder to get the chemicals
we use. The chem section in any photo store is a pittance.. unless you live
in
NYC or LA, I imagine..... then what about getting the raw chemicals and mixing
your own solutions. Until last year, in Montreal we had a chemist who supplied
the photographic chemicals you needed, even for color, E-6, and in quantities
that you needed, 10 grams, 100ml or but she closed down because of a lack of
customers and inventory wasn't moving. Now I buy a 25kg bag of Sodium
Thiosulfate from a chemistry factory, but that stores easily and goes quickly.
But if I need Amidol???
We are addicted to a bunch of chemicals. Is there a list somewhere that gives
the commercial names/product names of the very chemicals that we use, like the
example of Arm&Hammer baking soda/Sodium BiCarbonate...... You can get Sodium
Thiosdulfate at the swimming pool supplier.... what can you get at the grocery
or hardware store, the pharmacy???
Maybe it was on this list, a long time ago or another, seems there was list
complied of commercial household chemicals that suited our needs, perhaps in
different dilutions but still available.
What mailorder photographic chem houses are there in the US? For me, of
course,
there is the transborder shipping and restrictions.
Cheers,
Bogdan
