You're interesting me as I have some difficulties to find
sodium metaborate but have borax and sodium hydroxyde ...
What's the procedure ?
Do you really make sodium metaborate in crystalline form to
re-use it later or do you just mix the proportional
quantities of both directly into the final
developer/fixer/... solution ?
So I went from commercial chemicals to mixing raw chemicals,
and now I'm going to make the raw chemicals ...
Anyone having the formula to change lead into gold ? :-)
Thanks,
Claudio
The metaborate is formed in solution. The formula I
gave is for the equivalent of 100 grams. If the formula
calls for some other amount multiply or devide the amounts
in the formula by the amount you need. I probably also have
the molar amounts somewhere but I think this is simpler for
non-chemists like myself. For convenience its possible to
mix the metaborate solution separately in a minimum quantity
of water and mix that with the soluton you are making.
