Non-Chemical Processing gold plated glass and china

[rainmaker]

I mixed 8 oz. Sodium Nitrate with 16 oz of HOT water(marketed as "Spring Water" from a national supermarket chain), filtered that mixture into the coffee pot glass container (carafe) and added 1 Qt HCL (Muratic Acid). This is the point I noticed that there was about 1/4" of white powder on the bottom of the glass container. I had not yet attempted to process any PMG bearing materials.

Did you forget to chill it after you mixed the Sodium Nitrate and water to remove as much salts as possible. :?:
Any H2SO4 ?

My Solution was never at boiling temperature, except the pure water prior to adding anything. Probably around 180/160 F when Sodium Nitrate was added and dissolved.

That is alot of aqua regia! And the recipe you quoted sounds eerily familiar. I think that the white fluff on the bottom was basically sodium nitrate that didn't completely dissolve as well as the salts from same. I have never dissolved the Sn in hot water before. I always just added in the SN, the water (room temp. tap is what I use), and then the acid. I believe you add acid to water and never water to acid? Someone please correct me if I'm wrong!

I literally had like 100lbs of this stuff that my urban miners and dumpsters divers had brought to me. I put it in a burlap sack and let the kids go at it with a hammer. Ever seen Steve's acid peroxide video? Use those same buckets for processing and simply dump the broken shards into the inside bucket and let it soak. Once the gold was stripped, I just had another rinse bucket with clean tap to rinse the china off with and then the pieces went right into the trash. Started all over on the next bucketfull.

I have no idea of the return. From reading on the forum, I didn't expect much of one so I evaporated it down and put it in the stock pot.
