Silver porosity


#1

Dave,
I used to have the same problem with silver. I do alot of casting
in both
gold (mostly) and silver. I found a great sterling silver casting grain from
United precious metals. This stuff is great. It is a deoxidizing metal and it
pours like butter and there is 75% less clean up after casting. That is to say
the castings have no hard to get off even after pickling black oxidation.
These castings come out like a dull satin finished silver. The name of the
metal is the sterling #57 casting grain. The name of the company again is
United Precious Metals. There phone number is 800-999-FINE. Call them up and
ask for some info. I use the stuf by the pound and I rarely if ever get
porosity…Try it you WILL love it.

Marc: I’ve heard of this stuff before but never from anyone that actively
uses it. Another question on this de-ox silver–I do ALOT of followup
soldering on the castings and wonder if you have fire-scale problems with
that kind of metal afterwards. Also, is this form of silver in any way
brittle at all that you can tell? In other words could I cast some prongs
in the piece and not have them break off? Thanks for the tips
guys…Dave

Hi there,
What’s in this casting sterling silver? Anyone know? Anyone asked?
I’d suspect they put in silicon for detail and phosphorus for the
de-oxidiser. The silicon would make a more brittle metal and if there was any
residual P again a metal that is a little short.
You people in USA would be better able to call the 800 ph # for more info on
this. If they disclose.
See how you go.
Regards.

Dave,
This silver is great for soldering, rolling, pounding, hammering, anything
you can think of. The answer to your question about it cracking is: NO, I have
no problems with this stuff cracking. The first version of this metal did do
just that but after reformulating the casting grain, the new version is just
perfect. I really can’t say enough about it… Try it out and let me know what
you think…

Brian,
I don’t know what it is they put in the metal to make it a deox. But I do
know that the metal itself after it is casted or whatever is absolutly NOT
brittle at all… Also if you are suggesting that the metal may not truely be
sterling, well here in the UNITED STATES we have laws against
misrepresentaiton of this sort of thing…

Hi Marc.
No I wasn’t insinuating that the metal isn’t sterling - It only has to have
the requires % of silver to comply, Right? It’s just that the REMAINDER is
not often disclosed. I’d like to know what is in this sterling, in the 7.5%
part.

I really don’t know off hand. I will have to dig up the literature on it and
see… I will let you know if I can find it… the Metal is really great to work
with though… Try it out and you will agree…
