List: According to George Martin, "US silver coins prior to 1965 consist of 90% silver and 10% copper." So, if George is correct, and I have no reason to doubt him, all of what Frank said (see below) would be correct because I don't believe the couple of percent difference between my 92.5%/7.5% silver copper alloy and coinage metal would have made any difference in the results. To summarize: Silver METAL not silver ion is the active species that keeps water, and presumably milk, fresh. I suppose natural convection would create enough circulation to clean quite a bit of water or milk with just a single silver coin. Roger
