Hi, on the advice of many, I refined the gold again, the result is good! I boiled the gold dust in hydrochloric acid and then in distilled water several times.

Nice button, complete with a small dimple
Even the colour of the liquid and powder look good

Very nice button!

Be very careful working with these acids inside, you need a fume hood at best. A fan in a window will help.

While I feel it ruins the looks of clean gold a sign of good purity is how soft the gold is. Lay a piece of gold in the palm of your hand and rub your other hand across it one time. If it is fairly pure your skin will scratch very fine marks into the gold. Over time you will not need this method as you will see other signs.

Hi, I use this when I work with acid. I usually do a "water test" with gold. Specific gravity, volume, etc... Pretty accurate

Good mask it's good to be safe . Just make sure you do this faaaaar away from kids family . No mistakes on safety .

I would not trust that mask.

It will not stop the fumes from being on your. Cloths, shoes or furniture and walls.

Ones you start refining and that feeling of making gold fro A to Z . There is no going back .you will keep looking to make more . It's good hobby .but if you knew how to get more stuff .You will make a lot of profit . Good luck in Hungary I think there good opportunity to buy old jewelry .from yard sales thrift stores .

Hi, the process takes place in the yard, exceptionally the video was made inside, but this is not typical, otherwise this is not part of the house, it is a workshop.

Hi!
Thanks for the reply!!!
So when making aqua regia, isn't the 3:1 ratio important?
Hydrochloric acid and add the nitric acid until it starts to dissolve the gold?

Just trickle the nitric acid as the excess can redissolve the precipitant.

Hello!

I have noticed that since I have been using urea, the gold has been reduced differently. It becomes a very fine mud, which settles very, very slowly only to the bottom of the glass. After that, it is more difficult to deal with than if I had done the process without urea. But I'm afraid to work without urea...

Sorry mate, we do not recommend urea, that is a fertiliser that’s it, use Sulfamic acid at 70-80 C

Hi!

Thanks for the reply! I ordered some of it, would you like to know how to use it? For AR in powder form as long as there is a reaction? Thanks
