Hallo PT, Yes, normal house wiring copper is fairly pure. But it requires special equipment to make pure copper colloid. ( think it is very high voltage required) However, from memory, making colloidal copper-silver with a silver maker is quite possible: Make some colloidal silver, then swap the silver rods for copper rods and complete the process. How to check the ppm or strength? Keeping quality? particle size? Hmm. There was a discussion of the subject some years ago. Dont trust me , go to : https://www.mail-archive.com/silver-list@eskimo.com/maillist.html I typed in 'copper' and there is a wealth of info there. :-)) OK, Tony

Has anyone on this list made colloidal copper? If you have how did you do it? Thanks. PT
