HEY AllenMI. I got me a 12 vdc 1amp power supply for my coin cooking. So how long do I......

....cook my silver before it is good enough for the second cleaning (baking soda) process?

How long did you say you cooked them for?? And do you use baking soda to clean them after the electrolysis?

I use a 12v, 300 milli-ampere unit for my electrolysis. 1 amp is enough to disrupt your heart rhythm, if I remember right.

I would set it up, and stand over it while you're "cooking" it. After about a minute, and especially if you see black "stuff" flaking off it, turn it off, pull the object out, and rinse it. If it's still got some crud on it, hook it up and cook it again for about a minute. Once it's clean, go at it with the baking soda.

I would try this with a tarnished common-date silver, if you have any.

....black stuff flaking off of a coin during the process. I don't know if that has to do with the solution I am using or the lower voltage that I was using with the 3 and 6 vdc power supplies.

I do have some cruddy common silver to play with. Thanks for the heads up, I promise I won't do the 2 hour dunk with the 12 vdc supply.

is either silver oxide or silver sulfide. The only time I ever have a silver target with that much corrosion on it is when it's been in the water for years. Silver that been in really moist dirt for years will be stained, but should have a thick corrosion layer on it.

Good luck
