Hello, Mark

I would be very interested in treatment info on the Morro Redondo material,
per your response to a post from Tony Ruyter.

And here’s another potential topic for discussion: can anyone impart specific
on stripping precious metals after casting? I’ve found that many
intricate castings simply can’t be polished any other way, and I’ve done a
fair amount of electrostripping with cyanide and a compound sold under the
tradename Tivabrite. But, frankly, working with cyanide really bothers me:
who knows when one might encounter an acidic substance and generate the
dreaded hydrocyanic gas? And I haven’t learned of any effective way to
neutralize it prior to disposal. I’ve tried a couple commercial preparations
that claim to be cyanide-free strippers but haven’t found them to be
effective. Perhaps I’m using too low an amperage. Any experienced strippers
out there? (Hey, this could be interesting!) Thanks, Rick.

I sent it tonight attached to Mr. Ruyter’s further comment.please tell me your
opinion.But not on spelling and grammer.I almost flunked my FGA for atrocious
spelling and grammer.(Circa 1975)One thing I’d like to add as to why Toney
does’nt see top Brazillian materials at shows is because most often the better
goods are misrepresented as different locals.And in truth if you mix the better
Piaui Opal in with Australian it brings a better price then saying just
Brazillian.Most dealers do this,not just Opal.

Rick,

Have you looked into the new magnetic tumblers on the market? They use
magnets and very fine stainless steel needle sized media to get ito even the
smallest, tightest recesses. I think Swest carried one or two different
sizes of tumblers. Also, this months AJM mag has an artical on mass
finishing which give s quick overview of magnetic tumbling.

Thanks for the on magnetic tumblers – I presently use stainless
steel media in a non-magnetic tumbler but the size of the stainless pieces
isn’t fine enough to polish all areas. Since I live near a Swest showroom
I’ll check out what they are marketing and reference the publication you
mentioned as well.

Still, the results I get with electrostripping are very nearly worth the
risks involved, and if anyone tuned in has on cyanide-free
electrostripping or methods of using cyanide that allow neutralizing it at
completion (as well as recovering precious metals from the old solutions) I’d
appreciate hearing from them. Thanks in advance.
