This is in regards to making 20ppm colloidal silver. The Silvertron Jr. Manual states:
SilverTron Jr. has 2 selectable current settings. Use the High setting
if you have a stirring device to keep the solution well mixed, are
processing using a hot plate at near boiling temperature, or have a large
anode of more than a square inch of surface area, such as a bullion bar
My question is can I make the 20ppm using the high setting with only a Magnetic stirrer or do I also need a heated plate (heat source) ?
many Thanks
