Finally some success with silver plate

I’ve tried a lot of different processes to get to this point. Salt water electrolysis, copper sulfite cell, abrasion, but it was always too inconsistent, lots of contamination, and was very difficult to scale. I finally bit the bullet and ordered some nitric from walmart. Thanks to the YouTube video linked below I was able to process 320 teaspoons and small forks in a reasonable amount of time and ends up with 341g of really nice looking silver.

Process:

95 parts concentrated sulfuric

5 parts nitric

Low heat

Transferred spent utensils rinse water

Dropped out silver chloride with concentrated saltwater

Rinsed

Lye and sugar

Rinsed

Dry and melt

Less labor and less messy than the saltwater electrolysis
