Hello to all,
I wanted to experiment a way of processing pins that would save some trouble with base metals.
I tried something and the current result seems OK.
Since it is slightly different i wanted to present it for all to comment and suggest to see if its worthwile, could be improved...
Here is what i did:
Very small experiment (6 or 8 pins)
1st: A bath of 30% hydrogen peroxyde for 1 week with shaking and leaving outside to sunlight in closed clear container.
2nd: emptying the spent Hydrogen peroxyde, allowing time to dry.
3rd: Second bath with copper chloride + fresh Hcl with regular shaking with same storage conditions as above
Results: on the third day (today) i have nice foils (seeing them move in solution show they are not too thin. All pins have lost their foils.
See picture (i've pointed some foils, the remaining are under the pins or in solution).
I don't know if anyone has ever tried this, what problems they have encountered...
To separate pins from foils, i was thinking of keeping them stuck to the bottom by putting a strong magnet on the outside of the container bottom and normal rinsing and filtering.
If you have some ideas if this can work (or not) on a bigger scale (more than 8 pins :lol: ...) please feel free to share.
My best to all
