<p>[QUOTE=&quot;Derick, post: 1565985, member: 39142&quot;]I have been working in metallurgy technology development for the last 12 years and I think there is a possibility that these &quot;milk spots&quot; could be silver chloride occuring as a &quot;white&quot; toning or tarnish if you may on the metallic silver surface. This could be due to exposure, do not know exactly how, to hypersaline high or salt environments. Silver chloride has a very low solubility in water at ambient conditions, but solubility does occur to minor extent above 50 oC. It might be worth putting a coin with milk spots in distilled water above 50 oC and note if the spots dissolve.[/QUOTE]</p><p><br /></p>
