    This was a predecessor to Kodak Polytoner. I have two 
versions of the formula: One is from a Kodak handbook , uses 
Kodalk, and gives two variations for different colors, the 
other came from a magazine and uses Carbonate. I have tested 
the latter. It works but is very much faster than either 
toner alone, producing full toning in under three minutes at 
room temperature. I am pretty sure I have posted all this 
stuff to this list in the past. It should be in the 
archives. If not, and if anyone is interested, I will post 
it all again.
