UV Photo-decomposition can reduce Silver Ions (Ag+) to Silver particles (Ag) in a controlled manner whereby particle size is determines by the wavelength of the incident light. In this case we are using a UV-Led 3 watt rating at 420 nm which you can see changes the grey solution to a beautiful translucent appearance as seen the the photo gallery. We call this COLLOIDAL SILVER ENHANCEMENT. Please wrap your jar with Alu-foil to give best internal reflection intensity and keeping out the broader light spectrum from out side light. When processed pour into a green or brown bottle and store in the refrigerator.
