Dear Orchidians, I have requirements of making specialisez
KEYCHAINS from Silver Sheet having 3mm thickness. I want to ETCH
silver metal 0.5mm deep and for that I need your technical help.Is
it possible to ETCH silver metal only by chemical dipping? Which
chemical and what is the process sequence? If only chemical process
is not possible, then how to do the etching by Electrochemical
process? Please suggest Chemicals and current details. Also please
suggest me reading material on this subject. Awaiting your positive
response, Thanking you, Sincerely, DINESH PATEL.
Dear Orchidians, In response to the question below, could I ask a
further question to go with it. I only know of Nitric acid for etching
silver are there any others? Could someone please explain the dangers
of nitric acid and how best to handle it? I know it makes your skin go
yellow if it gets on you. How do you store Nitric acid safely and in
what sort of containers?
I used it a long time ago and I think it was watered down, we had to
put a resist on the back where you did not want to etch. We wore thick
rubber gloves goggles and face mask, it was quite daunting. I got some
excellent results but the whole chemical process and danger put me off
so I did not continue to use Nitric Acid. Marjorie.
