Try Clerc... (as I recall). It's in the old lit & I will reprint when I
can get to those files... Tho I think it's also in the alt-photo archive.
Search for ..... "mordancage" ! (I'm pretty sure I put formula on myself,
also Peter Marshall did, possibly different version -- among others.)
Meanwhile, I have a bottle of (expensive) 30% hydrogen peroxide sitting on
the shelf these 20 years -- probably dead by now -- because process worked
fine & dandy with regular 3% from drugstore, 59 cents per pint. Just
increase ratio to water.
