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 John .----- Original Message ----- From: Carol Ann To: [email protected] Sent: Friday, April 28, 2006 11:45 AM Subject: Re: CS>Re: Bulk CS
wow. Why the brass plate. Why wouldn't the paper towel contaminate the solution. HRBE <[email protected]> wrote: 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.
