<p>[QUOTE=&quot;Greg Clark, post: 2564642, member: 83030&quot;]I appreciate the candor and I do realize the problems associated with this type of medium.

I have a method to produce great tones in just hours and they do not look artificial.</p><p>The process requires reactions of chemicals that produce harmful and even deadly gases if inhaled. If you are interested in this study you can buy a book written by a chemical engineer I know. We met at the Chicago Coin Expo over 20 years ago. He&#039;s an avid collector of silver dollars and at the time was a specialist in Carson City coins. I haven&#039;t spoke to him for a decade but I&#039;m sure he is still writing and working with coins and improving on the chemistry of preservtion, restoration, cleaning and toning. </p><p>The book is Coin Chemistry by Weimar W. White</p><p>He&#039;s much more involved in writing and has written many articles for the Gobrecht Journal, Coin World, COINage as well as other publications. </p><p>I know his work will cover everything I use for silver coins but I do not believe he has written anything for copper. I could be wrong.</p><p><br /></p><p>BEWARE: IF YOU ATTEMPT TO PRODUCE HYDROGEN SULFIDE GAS TO TONE SILVER......UNDERSTAND THIS GAS CAN KILL YOU.[/QUOTE]</p><p><br /></p>
