I find the comfort and trust with each other that is between all the men in this video is such a change from the street life one encounters in North America. These guys may not have all the material things, but they do have a a strong honesty and connection with their community. It’s wonderful to see that.
This is craftsmen ship that has been done for centuries! These are skills that are lost on many in our modern times. Never should one complain about the cost when you see what talented work is needed to create these masterpieces!
1st, I appreciate your video, but I am astonished that this man would use this acid without some type of respirator because the fumes, the red fumes are life threatening.
Why is their work station always crude and on a carpeted ground? Have they never heard of counters and chairs? They're dealing with precious metals; surely they could afford it!?
He used a drop of nitric acid to dissolve little silver and convert it to silver nitrate, then tested it with brass key. Brass is an alloy of Zinc and copper, so it reduces the silver nitrate to silver powder back. He added Nitric acid from the black can to dissolve the silver material to get silver nitrate solution with other impure metal salts. He selectively precipitates silver with copper plates. Blue solution is copper salt solution. You can see the difference clearly from the initial weight and final weight. There is some loss. So, you can understand that silver material was not so pure.
No need this is very crude method, since he is an expert he handles cautiously. But for layman safety first, handling acids are dangerous, you can see the brown fumes, not an healthy thing, currently many suppliers give safe equipments to handle them safely.
@@theinvinciblejeweller2932 or the joy! I do this and it’s amazing. Privileged to work with precious metals from our Mother Earth! Make beautiful objects to give and sell.
NICE VIDEO, COULD YOU EXPLAIN THE SOLUTION IN THAT SMALL PLASTIC BOTTLE, & THE TESTING PROCEDURE DONE WITH THE KEY, WHAT MATERIAL IS THE KEY MADE OF. THANKS

For those who don’t know. That’s real currency right there. That’s what American government doesn’t want us doing because they don’t want to pay real money.

1:02 Oh Thank God they Have Decent Air Ventilation System to suck all of the Dust, Smoke & Chemical Vapours otherwise it wouldn’t be good for their lungs good on the Worksop Owner to Supply Adequate Saftey Gear & Equipment there.....
The silver nitrate is in solution and the metallic copper will dissolve to form copper nitrate; as it does, it will precipitate the silver in solution as metallic silver. That is, copper is exchanged for the silver in solution and silver is replaced by the copper that is not in solution.
