My solution to this problem is to stop working in 10Kand work only
in 14K, so that a mix up is not possible. What doothers do? Well,
MT. I'm not a snob - don't know if sometimes it may seem so, but
I'm definately not. ~Except~ that I consider 9 or 10 karat gold to
be the scourge of the Earth. Exceptions are things like Black
Hills Gold where the richer colored golds are desirable. That's
beside the point, really, because it's still going to blossom on
you the more you work.
We have, in our shop: Sometimes a bit of 10k, but I looked yesterday
and I’m out. 24kt, 22kt, 14kt yellow, white and rose, 18kt yellow,
white and sometimes rose, iridium platinum, cobalt platinum, fine
silver, sterling silver. And a box of brass, copper, nickel silver
and bronze that’s for utility things. I have a certain amount of 14k
white and yellow mixed 50/50, which is a peachy color that can be
pleasing. And findings and misc. and that doesn’t incude stones. Then
there is solder. We don’t use medium solder at all, but we have two
solders for each metal, pretty much - 12 or 15 solders, maybe. First
off, we recycle everything that’s recyclable. I work over a newspaper
and save the filings - I just take the time to clean up before I
rubber wheel or change metals or whatever. Years ago I had a roommate
that was an amateur photographer. He gave me a stash of bulk 35mm
film cans. They’re seamless metal cans about 4" wide and 1 1/2" high
or so - perfect for holding bits of metal, and each metal has it’s
own can. Those are going to be impossible for others to find, but
there’s all sorts of candy containers and the like, out there. You’ll
find it useful to use the same containers for all of your metals,
just for stocking and stacking in the safe. If I turn mine upside
down, the filings will stay inside, that’s how tight they are. For
findings and solder we use those compartmentalized plastic boxes. My
findings are just stray parts, as I buy them as needed, for work. So
I just have a spot for settings, one for catches, one for earring
findings, just very general. Then we have a large drum for floor
sweeps, and a plastic refinery jar for bench sweeps, and I have a
small jar for “pure” metal that’s too mixed up to recycle, like if
you file white and yellow gold together on some two-tone job. And
another jar for “pure” metal that contains platinum, as the assay is
different for that. It might sound like a lot to do, but it’s just a
system. Once the system is in place it just happens naturally every
day, which is what systems are for.
