<p>[QUOTE=&quot;Theodosius, post: 7824080, member: 77077&quot;]Hi, what I was trying to say is if it is light green and powdery and rubs off then it is bronze disease. If it is hard and stable and doesn&#039;t rub off easily then it could be a more benign patina.</p><p><br /></p><p>If you are suspicious of those green ones keep soaking them into distilled water and change the water out every day. Brush with a soft toothbrush every day and see if the patina changes. If the water turns green and you&#039;re losing material then there&#039;s more of a chance that it&#039;s bronze disease.[/QUOTE]</p><p><br /></p>
