db,

Please let us know the final weight after the foils are dissolved, precipitated, and melted.

What a disaster! My glass canning jar fell apart inside my cooler (note jar in picture) so I had to pan for gold particles out of 2 gallons of hot acid/water.

Regardless I got everything, here is what was done (about half) and the rest is in the acid again. All this from about 5oz of material and half is still in jar.

A good lesson on having an external safty bucket with your jars.

use a heat resistant NON-metallic (Pyrex or corning-ware) container and gently heat them.cover them will a cover or at least cover with a paper towel to keep

The glass ware weighs .11 pounds and once I removed the water the combined weight was .17 pounds so roughly .85 troy ounces out of 18 ounces of scrap

There is still some green at bottom once I took out water should I wash this with HCl some more?

nice closeup of what you got, when you gonna melt it down?

Why would he even consider melting it?
They are just foils and still dirty. They have to be dissolved and processed properly. What he did so far is that he reduced most of base metals but now need to do actual refining to get pure gold.
