Making glass powder pictures

I think I have seen most of the methods used for applying and working color
to
furnace worked glass, but this last Sunday, after I finally got my equipment
set up
and working for a day of hot glass, I got to thinking about pastels.

During my fall vacation in Louisiana in November, I picked up a package of
oil pastels and did some drawing and coloring on the rainy days. After I got
back,
I got The Encyclopedia of Pastel Techniques [Judy Martin, 741.235 M381E 1992,
Running Press, Philadelphia, Quarto Publishing London, ISBN 1-56138-087-3] and
enriched my limited experience with art color techniques by reading through it
and
working a few exercises. I was most impressed by the range and control of the
techniques.

So here are my questions: has anyone compounded powdered glass color into
something resembling a pastel stick? What material did you use for the
compounding? [Alternately, can you name an artist that apparently uses the
technique?]
I am interested in getting the image onto molten glass (as in arranging
powder on
a marver and rolling it)
Having used the glass powder stick so as to be able to draw a picture, what did
you draw on? Beyond the marver, has anyone drawn on paper and picked up the
glass powder from that (burning the paper off)? Has anyone prepared
compatible flat glass, painted/drawn on that, preheated it and rolled it up on
the gather?

I once had a recipe for making crayons with glass enamels. It involved mixing
the enamel powder with gum tragacanth and casting crayons in a modeling clay
mold. I never tried it and can't locate the recipe right now.

My guess is that you could blow a vessel and anneal it. Crayon on it and
reheat to 1050F. This works with painted enamels ala Cappy Thompson.

Yup. There are a whole series of color application methods that involve
working
the glass cold (enameling, gral (sp?) either changing color applied hot or
applying
color cold. But I really like the dynamics of working glass hot and cooling
and reheating it too much like pottery. And there is the technique of using a
torch with a colored rod to draw pencil-like pictures on the piece while it is
being worked (ie it is
1000-1500F) as William Bernstein does (and others, I am sure.) But the
quality of
the drawing (and my drawing skill) is not what I want. I am more interested
in the
softer tones of powdered color rather than line work.
And of course, I could lay out the pictures in glass powder on a marver
plate, but
the way I do glass, I don't have a lot of working time and moving around
several
prepared powder pictures seems a formula for disaster or at least dismay.
Perhaps I should just arrange drawing on the plates with a medium that sets and

burn that off in preheating the plate.
But I was curious.

How does one go about creating glass powder. I am guessing a special
grinder is required, but I wanted to know if there was an easier way.

Henry Halem's GLASS NOTES, A REFERENCE FOR THE GLASS
ARTIST includes Walter Lieberman's recipe for making
GLASTELS(tm), which are the %22crayons%22 mentioned above.
They can be used either hot or cold(on a sandblasted
surface and then fired).
Check my website. We sell books for glass artists and
collectors. You'll find a link to Henry Halem's site
so you can order a copy of his book directly from him.

Would like to know what page. I looked through my copy, checking the
contents of the most likely sections (and several unlikely), but didn't find
any reference.

Your proposals and ideas are really intriguing. I can suggest this
buy Oil of Clove- and mix it with the powders. Oil of Clove is used as an
extender in China Painting (ground glass enamels...basically)
and burns off clean.
so - you could either mix the glass enamels and "paint" them on surface of the
marver-
OR make a "sand painting" Navajo Indian style- by drizzling the powders
through your fingers, using small enameling spoons, a straw, etc. Then lightly
mist the whole picture with either Oil of clove or one of the commercial enamel
fixatives.. this would hold it in place...
blow and roll.??? Of course - I would guess one needed two marvers - one to
work the piece from - and one to have the drawing set up on....

I would be sorely tempted to experiment a lot!
let us know if you produce something along this line... sounds interesting.

This is in reply to Mike Firth about which page in
Halem's book you'll find Lieberman's GLASTELS(tm).
I've got the 1994 2nd edition and it's on page 59 with
Sandblast Resist, Jack Wax, and Mold Separator.

Wierd, there must be more than one 2nd edition. In any case, it is on page 62

of the first edition and page 64-65 of the second edition I have.
Since Henry dropped it from the third edition, I hope I can paraphrase/quote
a
modest amount under the fair use provisions of the copyright law without
getting
too much of a blistering. He calls for 1/2 oz of gum tragacanth soaked
overnight
or longer in 24 oz of water. Mix after soaking On a sheet of glass put 2
ounces
(3 in the recipe section, 2 in the narrative) of enamel (powdered glass) and
add
a little of the gum solution with a little water. Use a palette knife (thin
flat blade)
to work the mix into a putty like mass, then roll the mass into "worms" on
newspaper and let dry. If the result is too soft - cumbly - crush them up and
add more gum. Too hard, crush them up and add more enamel. Use on
sandblasted cold glass to look like
pastels after firing, use on hot glass to look like crayons. Again, this is
Walter Lieberman's recipe for what he trademarked as Glastels.
Although Henry doesn't specifically say it, I assume you could roll the soft
putty
in a piece of newspaper to give a wrapper and a grip like pastels have.
Thanks for the reference,

Henry Halem

If anyone is interested in the in the Glasstels they can email me at

I'm sure that someone will reply with amethod of making glass powder, but I
find it simplier to call Olympic Color Rod for my glass powder. They have a
web page at http://www.glasscolor.com/. If you are going to use powder,
remember that breathing in glass powder is harmful. I use a powder box
which keeps me from breathing in the powder.

Evacuation booth/chamber.....dust hood......box with 5 sides and a fan
leading out....the best would have a filter instead of just a hose going
into the nieghbors yard.

A powder box is an enclosure with ventilation and a filter to exhaust glass
powder outside of the work area. We use a simple plywood box with a suction
device, i.e. fan, a filter and 6" ducting to the outside. When powder is
added to the hot glass, the dust particles are not being breathed.
