<p>[QUOTE=&quot;Just Carl, post: 801686, member: 4552&quot;]If your describing the greenish colored type of contamination, your asking about Sulfating types of problems. All Copper is effected by Sulfur in the air by the process where Sulfur rich coal has been burned in factories or power stations. Also, Volcanoes emit Sulfur into the air. Usually this is in the form of Sulfur Oxides. Mixed with the air, it becomes an acid and attacks many substances and Copper anything is one of them. In many areas if you look at Copper piping, you&#039;ll also see similar greenish contaminations. </p><p>And in some areas the amount is so high it is known as Acid Rain and has ruined many statues. The usage of Copper Ground wires in the ground by organizations in such areas also has proven to be a disaster. After some time all the ground wires and ground rods have dissentigrated into Copper Sulfate.&nbsp; </p><p>Just normal for many coins to get that stuff on them.[/QUOTE]</p><p><br /></p>
