Thanks for you comments on working with Cyanide… It’s very
reassuring to hear read that other people are working safely with
the minimum of safety gear. I guess I was a little paranoid
about it after the safety equipment manufacturers made such a
song and dance over all the equipment I’d need.
How do you dispose of the sludge that accumulates on the -ve
terminal? I use a stainless steel beaker with the -ve connected
straight on to the side. I get a deposit of silver around the
edge of the tank and I wondered how I should store it or dispose
I tried reversing the wires and trying to ‘plate’ it out but
ended up plating out what looks like copper. I guess that the
copper in the sterling silver is plating out but not the silver.
Ionic chemistry is not a strong point of mine. I had intended
filtering the solution out and scraping the sludge off the beaker
and melting it down if that’s possible (whilst wearing protective
gear of course).
As for general safety. I think you are right, fear is a good
protector. I also agree with your point that it is important to
remind oneself of the potential danger to avoid complacency. I
keep in mind the story of a caster who used to strip his
castings and ended up dying after biting his fingernails after
handling salts. I won’t even lift the lid on my beaker without
wearing gloves and mask.
Thanks for your help.
