Borax Co, the maker of 20 Mule Team Borax. It is chemically
pure, at least enough for photographic purposes and is
granulated. It should work in any photo formula calling for
Borax. Red Devil Lye is another "grocery store" product
(although I haven't seen it recently) that is pure enough
for photo use where sodium hydroxide is called for. One can
make the equivalent of Kodalk (sodium metaborate) by
combining the hydroxide and Borax in solution in the right
proportions.

Watch out for anhydrous borax. I foolishly
bought a large bag of it many years ago, just
because the price was attractive.
Anhydrous borax dissolves in water so slowly
we will all die of old age waiting. I could
find no additional chemicals that made it
dissolve fully. It's a nice white powder that
you can pour on the ground to mark your path.
regards,

Kodak used to include a warning about this along with
its formulas calling for Borax. It stated that only
granulated Borax should be used "because powdered Borax
dissolves only with great difficulty."

It may be true for both.

I bet a lot of people have been perplexed by
the difference between granulated and
powdered!

They sell the 'wrong sort' of Boric Acid as roach powder.
I found it will dissolve in boiling water. In cold water
one may as well be trying to dissolve sand.

minimums. When I have to mix something using boric acid, I have the
solution in a pyrex container on a hot plate. Heating it up allows the
roach powder to dissolve more easily. I haven't noticed any ill
effects on the resulting soups.
