Mineral Cleaning for Collectors, R. Duthaler & S. Weiß

Handbook for Collectors: Cleaning, preparation and storage of minerals
A fresh find in the Swiss Alps - a magnificient rock crystal comes to light. Fortunately, it was completely fully embeded in fissure clay and carefully recovered, and therefore remained undamaged. The sticky clay is quickly washed off at the top, but a tough coating of rusty brown iron oxides covers the sides of the crystal - and now the question arises how to remove it in the best manner ...

This handbook was developed by two collecting scientists directly from the practice and compiled during many years of work. This is the updated third edition of this work - in English and designedfor an international audience.
