Description: Since this video is published to coincide with the end of year holidays, I want to wish everyone a good time. In this video you will not find particularly precious jewels, but it is an excellent opportunity to show some techniques, used for the processing of precious metals, as I have tried to do in all my videos. I take this opportunity, to apologize, with all those people who have sent me their comments, and to whom I have not been able to answer, unfortunately the work commitments and not, leave me little time available.
