Gold from bagged Paydirt turns Grey?

[Butcher78]

I started getting bagged Paydirt back in 2019 - 2022.
I saved the bright yellow candy in a small glass vial and when I pulled it out today to see my saved gold it has turned grey in the bottle. Does anyone know why and how to bring back the shiny?

If it turned grey, it might not be Gold. A little Nitric acid would be a good test.

The profile pic is the B4 it went into the glass vial. The uploaded is now. I bought from 2 different company's. One based in Alaska and the other was from Arizona. The gold got mixed together but both changed color.

Might be mercury contamination, although I'd expect it to look a lot more silvery.
You could heat up a small section to see if it becomes gold colored again.
Look up cleaning mercury contam with a water retort on YT to see whats needed.

First step id contact the sellers and ask why.

I did look up that video. And I will have to give that a try. Nice thinking.

I agree that it very well could be mercury, and it would most likely be a gray color and not necessarily silver, it would only take 1 or 3 little pieces to have had mercury on them and it would spread to all the other pieces, it takes very little mercury for that to happen, however you try to remove the mercury, do it outside and AVOID you or anyone else breathing any of the fumes, this includes your pets as well!!

As I said in your other thread, it could be Electrum, with a high copper content that has oxidized.. ?

It’s almost certainly mercury.

Personally, I’d go outside where it’s well ventilated and put that gold in a large metal spoon (perhaps over a baking pan in case you drop something).

Focus a propane torch under the bottom of the spoon until it glows red. that should heat the gold up enough to burn off the mercury that’s coating the gold and return it to its pretty color without melting it. maybe dump it in a pan, then back into the spoon and repeat one more time.

then put it in a clean glass vial after it cools. But that’s just what I would do if I had dirty gold. Well ventilated with the breeze blowing away from the face is the key point. I would not want to breath the fumes that burn off.
