Sorry I mislead you, it is 99.99% pure solid silver in plate form, 3 mm
thick, not PLATED SILVER.
I figured if Bob Berger used a brass cathode in a rod form, the brass plate
the same area as the silver anode would make the CS faster and it did.

Interesting -- but I'm a little hesitant to use silver plate instead of
pure silver. How are you able to tell whether you are dissolving the
substrate? If you feel safe with your sheet-I just bought 25 lb. roll of
brand new sterling foil -92.5 Ag/7.5 Cu for scrap-16" wide It is as thick
as
heavy aluminum foil. I am trying to find a use for it. TJ Garland Noble

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
