hi, i've been reading orchid for a while. what a great resource.
thank you to all of you who post regularly. it's always interesting
to read the posts. i need help with a little problem. i was
wondering if anyone has ever tumbled aluminum. it wouldn't be
anodized. i want to tumble it in steel shot, but i was wondering if
aluminum particles will come off and contaminate the shot for
silver, since aluminum will pit silver. any ideas or help are very
much appreciated. thank you, alisa
