Tips & Techniques

Mike Durand submitted an article on rock/stone cleaning.
And a recipe for making rock/stone stabalizer/hardener.

The article for cleaning came from Inland Lapidary which was sold and is now Inland Craft. The old web site no longer exists. I called the new owner and he said the article is lost and not retrievable, so I had to scan the copy that Mike gave me. It's readable and that's about it. Sorry.

Mike also sent a link to a website that's all about mines! It's: www.westernmininghistory.com
