<p>[QUOTE=&quot;Hispanicus, post: 2443104, member: 72626&quot;]Ken,</p><p>Another atmospheric influence in the central valley is the smoke that hangs in the air when the rice fields are burned or the smoke we had last summer due to all of the wildfires. I&#039;m bringing this up because you see a lot of green bronze on buildings in Europe and I&#039;m told it came about via local air pollution, namely coal heating and wood cooking fires. </p><p><br /></p><p>Please keep us updated because I&#039;ve got Domitian and Vespasian bronzes that are harshly cleaned and have considered leaving them outside. However, I live in the SF Bay Area and would more than likely get different results.</p><p><br /></p><p>Best of luck in your experiment![/QUOTE]</p><p><br /></p>
