My one time effort at mylars was enough to show that there was not enough profit to cover the cost of chemicals, However it is a good learning experience for those who would like to get their feet wet.
In the picture below I have removed the silver contacts from an oven thermostat from a pre - electronic electric range. The contacts are solid buttons not plated, it's my estimate from an electric range there is over an ounce of silver if you include the thermostats from the heating elements.
The silver contacts are not pure silver, the buttons in this case have been alloyed with palladium to toughen them up.
Ballymoss I beat google in scanning the Hokes books by a year or more then posted the scan to GRF, you may recall that Hokes Testing Precious Metals was purchased with donations made from GRF members, I received the hard copy then scanned it making the digital available to all.
Nothing beats having the hard copy, I have Butts and Cox, the Economics of Silver and Its Uses, plus both of the Hokes and Ammens 2nd edition plus a few more titles on Electro-refining and recovery. Not to mention the numerous books I have downloaded from openlibrary.org
We should be discussing where to find silver not how to process or refine it on the scrappers forum, I tried to initiate an interest in this subject in the past but it seems most are only interested in posting about a broken fingernail or some idiot making a gesture with a box knife just to name a few off topic threads.
The we have the nerve to post in another thread that we're professionals, hope that person was not speaking for - ALL.
