In this video I refine old silver jewelry using homemade nitric acid to obtain some silver metal which I then magically transform into a high quality mirror while trying hard not to contaminate everything with copper.

If you enjoyed the video consider liking it, sharing it with a friend, and subscribing to my channel - I would really appreciate that :)

Also, excuse me for my poor speaking, English is not my native language so I have some trouble with pronunciation, in case you don't understand something there are always subtitles made by me.

Please don't comment about how stupid I am to wear nitrile gloves when handling nitric acid, I am aware of the dangers and don't need hundreds of people trashing the comment section.
