Ionic silver is made with electrolysis. Remeber the old days in chemistry class where you put two rods in a beaker of water and hooked a battery up to them? That electrical process produces oxygen at one terminal and hydrogen at the other. The electricity is able to flow through the water only because there are ions present (like salt which is Na+ and Cl−). These charged ions allow the electrical current to be conducted through otherwise neutral water.
By running electric current through water, it physically breaks down the bonds in the hydrogen and oxygen of water. This causes hydrogen to be created at one end and oxygen at the other. Using this example, if you then put two silver rods inthe water as your rods, you would kick off an electron as the current passes and create a silver ion. These silver ions would eventually clump together into what we would call silver rust. Eventually, they would preciptate out as black sediment in the bottom of the container.
True colloidal silver is not made with electrolysis, it is a propietary chemical process that produces colloidal silver with a complete valence electron shell. That's why we can product 10000 ppm TRUE coloidail silve with an indefinite shelf life if kept out of direct sunlight. Ionic is dangerous, limited, highly volatile and an inferior product.
