Alternative to pitch
Marisa Cappetta
am now resuming my jewellery practice and wish to use this technique. Are
there any alternatives to using pitch when I repousse or am I stuck with
this nasty, noxious stuff?

Try setting it into a bed of hot-glue-gun glue. These come in little
tubes that the gun melts. I've only done very small repousse with
this method, but don't see why it wouldn't work on larger pieces.
I also set all my stones this way instead of in stonesetter's glue,
but watch out for heat buildup from your flex shaft which will release
the setting.

You're not using the nice pine rosin version instead of the
petroleum-product one? Try looking for pine rosin and mix up your own,
making a hard, medium and soft versions. Makes the whole studio smell of
pine :)

Yes, I have been using the petroleum based pitch. I like the sound of your
pine rosin version. Do you know of a recipe for mixing the pine rosin? Can
you also recommend somewhere I can purchase the necessary ingredients? Many
thanks,
Marisa.

Hi
It seems that Northwest pitch might be pine rosin:

I discovered the 'NORTHWEST PITCHWORKS' and Anne Praczukowski. Anne
Praczukowski is an artist who uses chasing in her own art work. In the
1970's, her frustration with the pitch available in the U.8. was so great
it motivated her to experiment with making it herself. Beginning with the
universal recipe found in Herbert Marion's book (see bibliography), Anne
placed a five quart pot over a hot plate and, after four long years of
experimentation, came up with a Satisfactory batch of her own. This earlier
product was asphalt-base, but since 1980 she has discontinued its use. Her
formula is now made frona a 100% pine resin...
... Chaser's pitch can be purchased by the pound (plus shipping and
handling) from 'NORTHWEST PITCHWORKS', 5705 26th Ave. SeattJe, Washington

from Oppi Untracht: 'Metal Techniques for Craftsmen', (p95):
6 parts pitch
4 parts plaster of paris
1 part vegetable oil
Melting it is hard, as it does not conduct heat to other parts of itself.
I've heard that putting the rosin in a recepticle in the oven for a long
time will slowly melt it ready to add the plaster and oil.
The Bowl:
I have a great idea for a pitch bowl I got from an Australian repousse
artist Marion Marshall [drawing available]. Get a woodworker to turn a
large block of wood into a hemisphere and make a shallow indent in the top.
Unless you doo deep shapes ypu don't really need the traditional
thin-walled iron bowl filled with pitch. They often say to put something
else other than pitch, like lead, in the bottom part anyway, using less
pitch to fill the cavity. This wooden bowl is a great modern version, and
is solid and heavy.

Thanks so much for the tips on mixing the rosin. For a pitch bowl, I use a
cheap enamel bowl, the kind you use when camping. I'ts a smallish diameter,
but quite deep. I fill it about half full with plaster-of-paris and when
set, put the pitch on top. I sit the bowl on a leather sand pillow. The
plaster gives it a good weight, the bowl can be heated and all the materials
are readily available.
Thanks for your help
