Hi,
Thanks for the info on sodium metaborate. I found the following info in the
Focal Encyclopaedia of Photography. Sodium metaborate can be made in
solution by mixing 1 part sod hydroxide with 5 parts borax, both being
dissolved in water. This is equivalent to 7 parts sodium metaborate.
Thanks.
Mark.
