Keyboard Mylars

i just did a little experiment on mylars by a different route. i incinerated the mylar to ash before digesting the silver. the yield was, from 580g of mylars, i recovered 14.9g of silver. thats very close to the outcome here. http://goldrefiningforum.com/phpBB3/viewtopic.php?f=61&t=19251

If that's the case, then the question really comes down to preference. Incineration seems to be an easier route. No washing, after the reaction, of all the mylars. I'd prefer that just so there wouldn't be large amounts of fluid to deal with.

I prefer incineration due to the fact that you get your pure silver immediately and don't have to do any other washing or refining. I described how to do this here:

Melting the Mylar can be tricky, the key is to take things very slow so as the temperature does not exceed the flashpoint of Mylar. Once the Mylar is all melted you can pour off the bulk of it and turn up the heat a little to melt the silver and burn off the residual Mylar. Use the proper safety gear when melting Mylar.
