Hi Rojas, I suggest that you clean your bench everytime you change
metals …or setup 2 benches so that you can keep your silver and
gold filings/shavings seperate… This is how it is normally done.
The reason I say that is that it is too easy for a person buying a
mixed ingot to be cheated , likewise it is easy for you to loose
money. Telling someone you want $600 for a mixed bar of 250 grams of
metal does not identify the value enough to make it interesting.It
would have to be assayed to determine the value.
We go as far as having all our metals in seperate containers… we
seperate 14k, 18k 22k,24k, and silver … now, before sending it in
for refining, we burn of wood filings , use a magent to remove
broken saw blades… then we weigh each metal and deliver it to the
refiner that way… now, we know exactly what we should get back and
it tells us immediately which refiner is cheating and which one is
Hope this may be helpful to you. Best Wishes, Daniel Grandi
