>Potassium
>Can only be dissolved to about 11% for a saturated solution si is slower than
ammonium if you are working with saturated solutions. It has the advantage that
it can be dissolved in alcohol which dries more quickly which can be important
if you are dichromating gelatine forn carbon prints.
> and Ammonium Dichromate<
A saturated solution is around 33% so it is faster than the potassium. It will
not dissolve in alcohol.<
I think you have it the wrong way round my old mate it is the Pot Dichromate
that will not dissolve in the alcohol.
We must not mislead , getting into gum printing is bad enough ;-) .
