In actual practice, I rarely find it necessary to use the dichromate.
If negatives can be made to be printed without the use of contrast
enhancers such as sodium dichromate or potassium chlorate, that to me
is the best of all possible worlds. Sometimes a small amount of
H2O2 may be added to the "emulsion" to clean up the highlights but
that's about it.

Keith, your so right about nailing the negatives but ever once in a while
even the best laid plans go bad.... I've been doing some testing running alot
of prints through one solution and as yet have seen no contrast loss. Will
keep you informed. So far I have not seen any of the "grain" that is so
apparent with potassium chlorate.
