Central Alberta | Make sure it's pure silver. The wrong metal can be poisonous, or darken your skin,
the way that has been blamed on silver. Silver does not darken the skin, despite what the internet says.
The 10 ppm stuff you buy is practically useless. I make it using 99.999% pure silver wire, and it tests at 80-100 ppm.
I get the best results around 30 volts. You can get that by connecting 3 9V batteries in series. | |
