Constructing a 200mm Glass Vacuum Chamber for a Specialized Vacuum Deposition Process:
The construction techniques for making an eight-inch internal diameter glass vessel using a two hundred millimeter
kettle flange will be reviewed and explained. Information will be given to the specialized deposition process that the
chamber will be used for. Also detailed information will be shared about how the internal glass structure was
fabricated and the issues that confronted us to get 21 electrical leads inside the vacuum tight chamber. This talk will
be both educational and entertaining for the audience.
Joe Gregar is a fourth generation scientific glassblower who
began learning the art of scientific glassblowing 42 years ago in
1966 at his family-owned business, The Milwaukee Glass Works
Inc. In 1969 he became a scientific glassblower with Pope
Scientific Inc., in Menomonee Falls, WI. In 1974 was promoted
to Plant Superintendent and head of the custom glass shop.
While supervising all phases of production he was responsible
for teaching production trainees, apprentices and journeymen
glassblowers. In 1980 Joe joined Argonne National Laboratory
in Argonne, IL. In 1985 Joe was promoted to the level of
Scientific Associate specializing in apparatus design and in 1997
was promoted to Senior Scientific Associate. Joe has held every
office in the Midwest Section and was the National Secretary of
the ASGS between 1984-88, ASGS National President-Elect in
1989-90 and the ASGS President in 1990-91. Joe won the ASGS
Helmut E. Drechsel Achievement Award in 1989 and the J. Allen
Alexander Award in 1993. He has presented several technical
papers, a technical poster, and has demonstrated many
technical workshops at the National Symposia. He was honored
by receiving the first “William A. Wilt Award” in 1999 and again in
2003 for his workshop demonstrations. Joe is currently the
National Junior Liaison Committee Chair and has organized and
instructing the Joseph S. Gregar Junior Member Workshop
Seminar programs since 1988.
An Ultra Efficient Vacuum Trap:
Georges Kopp: has been blowing glass for over forty five years.
From 1961 to 1964, he attended the trade school “Les
Feuillantines” and received a C.A.P degree. He then earned a
B.E.I. from the Ecole Dorian in 1965. Georges has extensive
experience working with several companies that manufacture and
produce various kinds of vacuum gauges involving all types of
glass to metal seals. In 1969, Georges immigrated to Canada
where he worked for Canadian Laboratories Ltd. manufacturing
general scientific laboratory glassware. In 1973, he joined McGill
University as the Manager of the Glass Shop. Georges also runs
his own private company producing CO2 laser tubes and one of-a-
kind glassware for the pharmaceutical industry. He has taught
several Allan B. Brown Glassblowing Seminars over the years and
was the recipient of the Andrews Glass Award for the best
technical paper at the 2002 and the 2003 Symposia.
Jacketed Multiport 500ml Flask: A small
500ml flask has 8 ports on the x, y & z plane
incorporating a 3Liter flask as a jacket.
Doni Hatz has been a member of the ASGS since 1986. She
has held multiply positions in the ASGS including, President
2000-2001 and several committees. She is a strong advocate
for educational development and dissemination of information
with the ASGS, the Glass Art Society and International
Society of Glass Bead Makers throughout her career.
Doni Hatz is a scientific and artistic glassblower who started
in furnace glassblowing then found the art of scientific
glassblowing in 1982.
A student of Salem Community College then continued
expanding her skills at Union Carbide Corporation, State
University of New York at Stony Brook and presently with
Procter and Gamble Company for the last 20 years in
Cincinnati, Ohio.
University Glassblowing: Looking at what
makes a glass shop valuable to the universities.
Prototype work, catalog items, consultation and
design, community outreach, shop services that
attract new researchers and graduate students
and keep the experienced researchers in place.
Steve Moder: University of Toledo
A Glaze Process Using (b2o3) Boron Trioxide to Reduce
Adverse Affects of Alkali Vapor on Glass Cells: This paper
will describe how an alkali-resistant layer can be glazed onto
the inner surface of a glass cell by introducing an aqueous
(b2o3) boron trioxide solution, evaporating the h2o and then
melting the residual biborate crystals into an interfacial glaze.
Graham Driver-Schroder: is a graduate from Salem
Community College’s Scientific Glass Technology program.
He is a member of the Delaware River Valley, and Northeast
sections of the ASGS. He has worked under Dr. Mathew Hall
of Alfred University as a glassblower and lab technician.
Graham will be attending Umass Amherst in the fall.
Porous Walled, Hollow Glass Microspheres: Researchers at The
Savannah River National Laboratory (SRNL) have developed a new
medium for the storage of hydrogen and other gases as well as drug
delivery. This new medium involves the fabrication of thin, Porous
Walled, Hollow Glass Microspheres (PW-HGM) in the range of 1 to
several hundred microns.
