You should be able to locate dry pigments through any good art store. I
mean *professional* type art store. Many of the stores in San Francisco
carry powdered pigments. In a small town you may have to look at going
mail order. Daniel Smith of Seattle WA is one source. Check their big
catalog pp 110-111. Call 1-800/426-6740 or fax 1-800/238-4065. Hours
are M-F 6am-6pm, Sat 9am-5pm Pacific Time. Be sure to ask for the big
catalog - insist in fact.

You may have to experiment to arrive at the right amount of dry pigment
to use. This may depend on the particular pigment. Each has slightly
different absorption characteristics. The tube pigments are already
mixed properly in (mostly) a gum arabic base, I believe.
