Yes, I bought the bullion bar. Ran 2 half-gallon batches at 7ma -- about 2 hours per batch w/electrolyte. Started a third batch at 3ma before going to bed, so I'm not sure just how long it took. The Tyndall effect is much fainter on the 3ma batch.
I'll use the high current gallon for baths, and make a second half gallon at 2 or 3ma for general topical, oral, and internal use.
Thanks again. The Silvertron will make it much easier for me to supply family and friends with quality silver, plus I'll be using more of it now that it's so quick and easy to make. Best of all -- no guess-work!
