Mineral Cleaning for collectors (new ENGLISH language edition!)

Finally available in English! It is the only and most complete book on cleaning minerals by use of chemicals.

3/15/25 Sorry to say these are now sold out AND out of print. Next printing will be available after the Denver show in Septemeber; LIKELY with a price increase (shock!) If you wish to lock in at this price I will keep your order in back-order status with your PP payment. OR,  you can try again in 6 months or so, but at the new price.
