Pottery by Dai on thu 30 sep 99
I used to get the old sewing patterns (you know, McCall's, Butterick) from
fabric stores during their seasonal changeovers. They only have to remove
the envelopes to get their money back from the pattern companies; mostly,
the tissue pattern pieces go to the landfill. This tissue is wonderful for
wrapping and packing raku pieces, as it is soft and conforms to any shape
without undue pressure on the raku. Unfortunately, the pattern companies
have recently made the fabric stores sign a contract guaranteeing that they
will release their out-of-date patterns to no one except employees of the
store. I am really pissed about this---are the companies so afraid that I
might actually use some of those free pieces to make a garment that they
would rather see the whole works go to the landfill??! Not a very good
corporate citizen, IMHO. I think I should use some of this rant-energy to
write to the pattern companies and tell them what I think of their
policy---like they'd care.................

Dryer lint, of course. And I collect used plastic grocery sacks from
neighbors, stuff a whole bunch of them into one bag and tie the handles then
use the "wad" for packing material with Styrofoam egg cartons.

Hi David and other avid recyclers!
Indeed I have a few additions to your fine suggestions!
Copper wire (bare wire) can be cut into fine pieces with a "nippers" and
sprinkled on a freshly-glazed pot for the "halo" effect already mentioned.
I've also "wound" fine copper wire (24 AWG) around a sculptural piece, to
provide a "meltdown" effect.
Silver wire (check with a computer or electronics shop for scrap) wound
around a piece of sculpture produces a metallic "crystal" effect.
Old steel-wool pads contain the best iron oxide! One can mix the "rust dust"
from a dry pad right into the clay or a glaze for black splotches.
I "pounded" a slab of clay on a rusty metal table out back, for a darkening
effect on white or yellow clay.
Chrome from an old car bumper (1957 Buick) produced an interesting metallic
effect!
One caveat: when using the copper, silver, or chrome metals, be sure to use
lots of kiln shelf protection! These metals run at cone 1 and above. I
usually use old kiln shelf pieces (for smaller wares), to provide additional
protection.
Happy recycling!

On this line of thought I would like to suggest visiting this site:
http://www.uiah.fi/kll/research.html
There is some fascinating research using waste materials in the production
of tiles and bricks.

Milton,
Are you doing those firings in an electric kiln???

Last year I had the good fortune to visit the Glass and Ceramics
Faculty at the Helsinki (finland) College of Art and Design.
They were using old television screens to produce fascinating
glass items and I believe were also trying the ground up TV
screens in glazes.

Hi!
Indeed, I very carefully fire wares in an electric kiln. I've also used the
same materials in a gas reduction atmosphere.
Thanks for inquiring.

Dear John,
Danger,Danger, the coat inside the TV screens "will" [ not just can ]
cause cancer.
