Shukran Salem. I have tried this several times based on the information you and Kevin previously posted and comments from others but I have never been able to get
good results. These directions add more details so I look forward to trying them (though sadly I am in the process of packing my coins up for a house cleaning-rental-posting abroad process and won't be able to spend much
quality cleaning time until I am re-united with everything in October).
Does everyone use a dental tool and if so sharpened? What do you use, Joe and Ghengis Jon?? I tried the unsharpened
dental pick as in Kevin's older posts and could not remove enough dirt. I tried scalpel and removed too much.
Likewise, Joe and Ghengis Jon, do you do the whole things under bino microscope, or just the details? I do all my scalpel/x-acto
work under microscope but have never though of using it for "Desert
Patina".
Finally, as a related question, why do you find almost exclusively black
patina under the desert dirt but, conversely, rarely find black
patina under other
types of dirt? Chemical? Heat related??
