Here is all three parts of the video showing how the foils are lifted off the fingers. These videos are buried in another thread so I hope this is not
counted as a double post;
Part 1, using salt, vinegar and hydrogen peroxide to lift the foils from trimmed circuit card fingers.

Part 2, recovering the lifted foils for refining then dissolving the gold foils in salt and vinegar with bleach

Part 3, precipitating the pure gold with vitamin C

Useful precis of the process deltaH came up with.
It is a bit like Spam, as it could easily go in the main thread.
Much easier to Find like this though.

kadriver you know that pungent smell you get when precipitating with smb?well what does vitamin c smell like?

I didn't smell anything because it was in my fume hood. I'm curious though. Maybe I'll do it outside to see what kind of odor it produces.
