I imported 2200 grams of silver beads from India to use in some of my
necklace designs. I would like to determine more or less if the
silver content is .925, as promised. I don’t have a testing kit,
but my jewelry books say that is not reliable anyway. And not even
Rio sells the so-called ‘silver star’ to test the grade of silver …
I suppose because no one wants to go to the trouble to test silver
since it costs little anyway! The cupellation method requires too
many components to buy – it’s not worth it.
Why even bother trying to determine the silver content? Because I
don’t want to buy from a merchant unless I’m sure of what I am
getting, and I don’t want to represent in my own jewelry something
that isn’t true. So I am trying to crudely or roughly determine how
much silver is present.
I did a crude ‘meltdown’ test in a Neycraft kiln. The bead did not
melt even at 1700 degrees F registered by the oven pyrometer.
Therefore I suspect there is some nickel in these beads, but I was
unable to find any charts or graphs that would give me melting
temperatures of silver/nickel alloys. During the heating some fine
silver did come to the top of the bead.
Anyone have any suggestions or ideas of what the actual alloy might
