Subject: [pure-silver] Ferrotype Plate Polish
In the past Kodak sold a solution called Ferrotype Plate
Polish, does anyone
know what its ingredients
were or what today would be a suitable replacement? Was
it used in
conjunction with their Print Flattening solution?

I don't know what exactly was in the Kodak polish but
most ferrotype polish is just wax in a suitable solvent. Its
used on enamelled or "japanned" plates or on glass but is
not needed for chrome plated or stainless steel plates.
Some instructions for ferrotyping suggest the use of a
print flattener but its probably being used as a wetting
agent. A final bath in Photo-Flo is sufficient. The print
should be applied to the plate sopping wet and the excess
moisture squeegeed off. I have seen recommendations for both
roller and straight squeegees and have used both with equal
success. I don't think there is any difference.
I have two formulas for ferrotype polish but both use
rather hazardous solvents. I give them below as reference. I
believe that a suitable polish can be made using a safer
solvent like Naphtha.
Haloid Polish
Benzole (Benzine) 125.0 ml
Yellow Beeswax 2.7 grams
Use only the clear portion. Apply sparingly to the plate and
polish out.
This polish is suggested for both enamelled and chrome
plated plates.
Kodak P-1 Ferrotype Polish
Carbon Tetrachloride 32.0 ml
Paraffin wax 0.7 grams
Dissolve the wax completely in the solvent. Apply all over
the plate using a cotton swab and polish out using a soft
cloth like Canton Flannel until there is no visible wax
left. Excessive wax will cause the prints to have a greasy
appearance.
Note that Carbon Tetrachloride is a very toxic
substance, I really do not recommend using it for anything.
Again, even though Haloid (now Xerox) recommended their
polish for chrome plates they usually do not require any
treatment other than being well cleaned.
