Silver solder formulation for fine silver


#1

Master Surpin,

Are you able to suggest any silver solder formulation that I could
apply to fine silver without having to sacrifice a claim of fine
silver on the main work?

Or is fusing my only answer?

This is a difficult question. To make silver solder, one has use some
copper. Regular sterling is a good solder for fine silver. As far as
calling it fine depends on how many solder joints and how they are
executed. It is understood that soldering involves some other metal.
With disclosure to a client it should be ok. After all, it is not for
investment purposes. This has to be stated upfront.

Option of fusing will preserve the purity, but limit what can be
done. Fusing can be used only in specific instances. I can suggest
another route, which is using 950 silver. But one has to make it. I
am not aware of any commercial source.

Having the means to alloy your silver, cast it and mill it as you
please, do listen to Leonid.

950 Silver has none of the problems related to 925 silver. A mere
0.025% has a lot to answer for. Adhering to the ‘925’ has led to all
of those patented formulae, but 950 makes them irrelevant.

Buy your silver as fine silver. Alloy it to 950. Then you can use
925 as solder.

.999 is 99.9 %
.950 is 95.0 %
.925 is 92.5 %

so I guess if 0.025% has a lot to answer for, then.025 has ten times
more to answer for.

I have to say that’s the best advice I’ve heard in a while, units
notwithstanding. And I’m learning really fast that the art jewelry
niche that I’m falling into really doesn’t demand hallmarking.

Maybe I should revive the Britannia standard (958) so I can at least
refer to that in descriptions!

Thanks Andrew! Yes I mean a ‘Mere 2.5%’, a big difference from a
misguided 0.025%.

The benefits available are worth more than a few % of silver.
