John,
I'd be hesitant to use paper towel in a liquid made for drinking as
paper bleached with chlorine creates dangerous toxins such as dioxins.
Maybe a better choice would be to use unbleached coffee filter paper.

The brass plate is the cathode, so it isn't sacrificial, and no the
paper towelling, the type used in the kitchen, will not affect it.
I soaked them for 5 days in distilled water to see what would happen,
and the paper stayed intact, and checking the TDS reading, made no
difference at all

wow.
Why the brass plate. Why wouldn't the paper towel contaminate
the solution.

I have been doing some experimenting with making bulk CS.
I have come up with the following setup.
1 x 5 gallon (imperial) fish tank
1 x 36 square inches 99.99% silver plate
1 x 36 square inches brass plate.
1 x aquarium water pump
1 x 30volt DC power supply, with adjustable current regulation.
I spaced the plates @ 3 inches, I wrapped the brass plate in
paper towel to
prevent the gunge from being circulated in the water. I
limited the current
to 100ma.
By wrapping the brass plate in paper towelling I don't need to
wipe the
plate clean.
8 hours later, I have 5 gals of perfectly clear CS solution,
which reads
25uS on my Hanna HI98308 TDS meter.
I used current control because I didn't have the time to
"babysit" the
process
I used Bob Berger's book as a guide for construction and I am
building 45
volt dc current regulated power supply to try to shorten the
brew process
time.
Hope this is of interest to the group
