Hi guys,
I tried to refine some sterling, did it before never got any problems, and now... some kind of brown sludge appears.
The sludge appeared when I was cementing out my silver. Maybe I did not clean the copper tubing enough.
The tubing wasn't submerged entirely, so my theory is that it is also possible that there is some kind of copper compound contamination probably copper(I)oxide. This compound appears to have a brownisch red color.
In the pictures I already removed my silver crystals, the rest of the solution still contains a lot of silver.
Is there anyone who has the same experiance?
