A few weeks ago, I went to the big Sheep and Wool Festival held
every spring in Maryland. In one of the booths, I found a number of
chemicals that are used in photography (and others I don't know anything
about).
These were sold as mordants for dying yarn:
alum (potassium aluminum sulfate)
blue vitriol (copper sulfate)
copperas (ferrous sulfate)
cream of tartar
tannic acid
thio-urea dioxide
tin (stannous chloride)
urea
sodium acetate
keltex (sodium alginate)
sodium carbonate (listed as both washing soda and Glauber's Salts)
Most of these are sold as 4oz, 1pound, 5pounds (some 1oz and 25pounds).
The prices seem to be cheap (are they a different grade?). I bought
tannic acid (4oz for $3.10 vs 100g $15 from Artcraft and 100g $29 from
Formulary; 1pound was $8.40 vs $35 from Artcraft).
The large mail order catalogue contains supplies for a variety of crafts.
The store is called Earth Guild, 33 Haywood Street, Asheville NC 28801
(hours: M-Sat 10-6 ET), 1-800-327-8448, fax: 828-255-8593
