What makes it Amber if it only has 12.5 PPM and you can barely see a line? The more golden mine is, the denser the line because it is the particles that give it the color. Are you clarifying golden Colloidal Silver with H202 and dispersing to make it appear clear? When I do that, the beam gets much stronger and denser. I would think the PPM might go up due to particles breaking apart or something.
