    This process is used exclusively as a second refining step. Meaning, the initial Aqua Regia solution already contains high putiry gold that was refined once in to the area of 99-99.9%.

    Unlike The previous video (see link below), the gold dropped this way doesn’t precipitate as a cool lava lamp, but rather as fine brown powder that clumps together easily. Nice and shiny looking Dendrites might grow here and there. It is still very pure though :)

    ** The complete written tutorial which includes more pictures and exact amount of reagents used is now available here:

    This is the first time i’m uploading a video with narration. Hope you will find it more convenient and easy to understand.
