One standard method of producing "electro-colloidal" silver (it should perhaps be called ionic silver) is to use a pure silver electrode just above distilled water -- using a higher voltage. The silver electrode will dimple the water surface while being brought closer, and then the plasma effect will start. The silver will erode into both ionic silver and colloid-size silver particles. The result is a mostly ionic solution (90% or so) with some colloidal silver. The plasma is produced in an helium, argon or other mostly inert gas atmosphere so unwanted silver compounds (especially with nitrogen) are not produced. -- Dean -- from (almost) Des Moines -- KB0ZDF
