Tips for Jewelers Who Do Repairs
From Alan Revere
A FILE-SAFE PLAN:
Modifying Files for Working Near Stones
Most flat and square files—both
large hand
files and
small needle files—have cutting
surfaces on all four sides and edges. The
sharp edges are great if you want to carve a
90 degree groove into a piece of
metal, but
then can
be problematic for certain
applications,
such as finishing a bezel
setting. If you want to clean up the top of a
setting,
a file with sharp cutting surfaces and
edges all
around will put the stone in danger.
However, with a little effort, you
can modify a
file that
will allow you to play it safe.
First, prepare a safe surface on
the one side
of a
fine-cut (#4 or #6) square needle file.
(Note: You can also use the
following steps to
modify barrette needle files, which are great
for finishing prongs.) To do this, carefully
lay one
side of the file against the spinning
wheel of
a bench grinder and draw it across,
removing the abrasive cuts on that side of the
file. Repeat until the cuts are completely
removed.
After rough grinding, take the
file to an oiled
sharpening stone—the kind you use to sharpen
gravers,
drill bits, blades, etc. Hold the
file flat
against the stone and rub it back and
forth to
smooth the new surface and remove
marks left by grinding. When the surface is
smooth,
knock the cuts off the edges on both
sides of
the newly cleaned surface.
With all remnants of the original
cuts removed,
use progressively finer grits of abrasive paper
to bring
the surface and adjacent edges to a
polish. Begin with 220 grit paper held against
a flat
surface. Proceed to 320, 400 and 600
grit. Finish up with 4/0 polishing paper. The
file should shine on one side.
And with that, you have a file
that is safe for
finishing bezels and prongs. Keeping in mind
that all
stones can be damaged by abrasion,
place the
safe surface very lightly against the
stone and
file the setting to perfection.
This tip is from 101 Bench Tips
for Jewelers
written by Alan Revere and published by
MJSA/AJM Press.

CITRINE
Citrine is the yellow variety of
quartz. The
color actually ranges from a very pale yellow
through the yellow-orange to orange color of
the best
reddish-oranges of
of what
is called oxblood citrine by many.
Many jewelers do not hold citrine
in
exceptionally high regard, but the darker
yellow and bright orange material is not easy
to find
and seldom seen. When cut to proper
angles and polished properly, it is stunning
and creates beautiful and affordable jewelry.
While citrine does occur naturally
on occasion,
most of
it is the result of purposely heating
amethyst. Many bench jewelers have had the
unpleasant experience of getting the torch too
close to
an amethyst or citrine and winding up
with colorless quartz and a very unhappy
customer. I know it worked for me! Once done,
it is
done, so watch the heat around citrine
and amethyst. Barring sudden temperature
changes,
neither the ultrasonic or pickle
should present a problem.
Yellow citrine ranges from a very
few dollars a
carat for
native cut, light toned stones to
about $70
per carat as it approaches orange and
is custom
cut and polished.
orange material ranges from about $20 per carat
to $80
carat for custom cut stones, although
this material is increasingly difficult to
find,
because the amethyst required to produce
it brings
high prices in the custom cut market.
Both the Russians and Japanese
produce large
amounts of synthetic citrine for the gemstone
market. Actually, they produce amethyst, and
heat treat
the material just the same as if it
were natural. Because the material IS
amethyst,
it responds by turning some color of
yellow to
yellow-orange to reddish-brown. Just
as with
amethyst, lab grown citrine is
available for anywhere from a few dollars per
carat for
yellow, native cut goods to upwards
of $70-100 per carat for precision or concave
cut stones, where one is essentially paying the
labor charge of a highly skilled artisan.
The synthetic material is fairly
heat
resistant,
but can be changed to colorless
material by overheating, and it will crack if
suddenly quenched. The ultrasonic can be
safely used, and pickle has no effect on the
quartz family.

<=> <=> Tips & Tricks from
When I began in the jewelry
industry in the mid
1970s we used a mixture of
sulfuric acid and
water for
our pickle. This mixture is a
fantastic pickle solution; however, if you
splashed any on cloth, it would deteriorate the
fibers of
the cloth and any vigorous rubbing or
washing of the cloth would produce holes in the
fabric. Towels, cloth aprons, and even your
clothes were vulnerable to the pickle solution.
One night after we were first
married, I came
home from
work to a dimly lit house with a
candle lit romantic dinner on the table. My
wife greeted me saying that she knew this would
not make
up for it, but she hoped that I would
forgive her because she had ruined my new work
clothes. She did not know what she did, but
somehow while washing my clothes she caused a
bunch of
little holes all over them.
I enjoyed the evening, and waited
until morning
to explain the real reason for the holes.
I have since stopped using pickle
in my shop
all together. Lets face it. For those of us
who work
mostly in gold and coat the jewelry
with Boric Acid or some other fire coat, there
is no
oxidation on the jewelry from the
soldering process (or at least there should not
be any). The only reason to pickle the
jewelry
is to
remove the boric acid and other flux.
That is easily done in a detergent
solution and
we do not
have to subject the jewelry to the
harsh chemicals of Sparex or whatever pickle
solution you use.
I keep a small container on my
bench of water
mixed with the same cleaning solution I use in
my ultrasonic
cleaner only I mix it a little
stronger. When the jewelry has cooled after
soldering,
I place the jewelry in this
container to remove the boric acid coating and
fluxes.

Tips that make working with Platinum

TAKE YOUR PICK
Polishing Tiny Areas
To polish hard-to-reach areas,
sometimes the
simplest objects can be helpful. For example,
a wooden
toothpick can be easily transformed
into a
handy polishing tool. Simply break a
toothpick in half and charge it with polishing
compound,
then insert the broken end into a
flex-shaft. You can now reach into especially
tight areas. The toothpick will conform to the
area as
small amounts of wood are ground away.

Stone setting tips from Gemz Diamond Setting
http://www.gemzdiamondsetting.com/index.html
by Gerald
N. Lewy
Hand holding your wax is not the
wisest
procedure to do when setting stones in wax, as
the heat
of the fingers will distort the wax
you are
using. It can bend the shank out of
shape after a few minutes. I always put my wax
on a
wooden tapered spindle.
To clean out any leftover wax
fragments pick up
a round
bur and while holding it in your
fingers rotate the bur. Any excess wax in the
seat will
prevent the stone from sitting in its
correct place. Do not use a flex-shaft for
this procedure.

Workshop Safety Tips From Charles Lewton-Brian
Quantity, Quality and the
Individual
The quantity of chemical you are
exposed to,
its concentration and the length of time
exposed, all
influence what the effects of
chemical exposure are. The individual, their
medical history, their genes, their health and
habits also influence what the effects of a
given chemical or material will have on a
person.
Cancers may be caused by materials
identified
as carcinogens. In general carcinogens have
no
safe level of exposure.
Chemical and physical agents in
the workshop
can cause
cancer. Entering any Californian
building that houses jewelers one is struck by
the warning notices on all doors: You are
entering a building containing chemicals known
to the
State of
Frightening, and
true. Like all chemicals
though,
exposure, time and concentration all
contribute to the risks. You can do a great
deal to
lower your risks in this regard.
Asbestos exposure is at this point
the best
known cause of occupational cancers and reading
the monthly occupational health and safety
magazine death reports it seems to be a really
major cause of death from job related cancer,
even now,
years after asbestos has been
recognized and removed from contact with most
of us.
There is some evidence of raised
rates of
stomach cancer amongst jewelry industry
polishers. Presumably this has to do with
larger particles being caught in the mucus of
the upper
parts of the lungs and being removed
to the
esophagus by natural clearing
mechanisms,
where the mucus (and contaminant)
is swallowed.
