Making large objects from clay takes a lot of patience, sweat
and dexterity, but making tiny pieces of jewellery can be
another challenge altogether. For those of you who have decided
to venture off into this delicate art form, here’s a few tips to
get you started and keep you on the path to making some fine,
wearable pieces you can be proud of.
List of Supplies:
Small sponge Wooden rolling pin Hole cutter Cutting wire Pottery
knife Fine sable watercolour brushes Metal findings (for
earrings and brooches) Face mask (for firing)
Be Prepared
You want to make sure you have everything at your finger tips so
that you don’t have to run to the store midway and come back to
a hardened un-useable lump of clay. You can find supplies at
most pottery stores. Greenbarn Pottery Supplies in Surrey, BC is
one of my favourites.
The Right Clay for the Right Job
Porcelain is the best type of clay to use for jewellery because
of its refined quality. It is smooth, pure and becomes very hard
after being fired at 2200 degrees.
Shaping Techniques
It can be a fun exercise to pound away at your clay and throw
great lumps to vent your frustrations, but for jewellery, a more
delicate touch is required.
After rolling the clay to about 1/8 inches thick, use your
pre-shaped cutter to press down and create uniform shapes, just
like making cookies. Or for the more adventurous types, make
your own shapes using dry hands, and a small sponge to smooth
out the edges. Using a picture for reference always helps but
remember to make the pieces slightly larger to allow for
shrinkage. A word of warning: thin shapes can be broken very
easily. For example, the thin legs of animals should be avoided.
For a look at some effective shapes, take a look at the animal
pins on my website at www.winnietam.ca.
Making Holes
Now that you have your shapes ready, it’s time to put in holes
for earrings, necklace chains or brooches. This can be done by
using hole cutters of varying sizes, found at any pottery store.
Don’t make the holes too close to the edges, as they can easily
break.
Painting
This requires good eyesight for the fine details and a steady
hand. Under glazes are the only type of colour to use as they
can withstand the high temperature of firing. The only drawback
is that you cannot see the exact colour until the final firing,
so this will take some trial and error.
Use a fine, sable watercolour brush and add one colour at a time
to build up to the final picture. For those who have taken any
watercolour or oil painting classes, the same techniques apply
going from light to dark.
Firing and Glazes
Now it’s time to put it in the oven and wait for the glorious
results. Be aware that the fumes from firing are deadly, so
extreme caution must be used to avoid gas poisoning. After
firing it with the colors painted on (4 times), apply glaze on
top and use a wet sponge to wipe off any drips at the bottom of
the piece. A clear glaze can be used or a mother of pearl luster
adds depth and brilliance. I usually paint on 22K gold luster to
the edges, using a fine brush, however this can be very
expensive – a 10 gram bottle is $270.
Attachments
It goes without saying that hypo-allergenic metal is the only
kind to use for attachments, especially earrings, for health
reasons. Always apply your attachments after the final firing.
The best glue to use for brooches is Goop Houseware Glue. It
takes 24 hours to cure.
Support and Reading
Making pottery alone in my studio is very therapeutic and
relaxing for me, I can get very absorbed in the process.
However, for those who prefer to learn and exchange ideas in a
group situation check out the Potters Guild of BC at
www.bcpotters.com . You will find workshops, networking
opportunities and discussion board, all very helpful for those
starting out.
A great magazine filled with pictures, articles, contests and
suggested reading is Ceramics Monthly. Many potters send in tips
they’ve learned along the way and it’s a good magazine to see
some incredible pieces. This is meant to inspire, by the way. Be
patient, keep practicing and before long you will be presenting
friends and family with your beautiful treasured creations for
many special occasions to come.
