Two possibilities I can think of. The silver oxide dissolves into H2O2, and thus the silver cleans up, until the peroxide saturates, then no more can dissolve, but it keeps forming on the silver. The silver oxide reduces to silver metal, but over time, the silver metal reacts with H2O2 to form silver peroxide which is insoluble.. This should be easy to eliminate one possibility. Do the experiment once, then take the silver with the black on it a second time, and put it in a fresh glass of H2O2. If it clears off again, the first possibility is supported, if it has no action, the second possibility is supported. Marshall -- The Silver List is a moderated forum for discussing Colloidal Silver.
