Seminar 2: “Lampworking History”
Presenters: Beth Hylen & Eric Goldschmidt
Monday, June 17, 1:00pm – 5:00pm – Rakow Library Seminar Room

In addition to the work they do at The Corning Museum of Glass (CMoG), they are also flameworking artists with a passion for learning more about the historical background of the technique. After exploring this topic independently for several years, they joined forces to research and lecture together.

This overview will explore the ancient beginnings of working glass in the flame and the flowering of the technique during the early Renaissance in cottage industries and science. We’ll also touch on the traditions of itinerant glassblowers, the glass of Nevers, glass eyes, industrial uses such as light bulbs, and more. The workshop will conclude with tours of the CMoG galleries and the Rakow Research Library, viewing lampworking treasures in glass and on paper. You will also learn how you can pursue your own research on the history of glassblowing.

Beth Hylen is the Reference and Instruction Librarian at The Rakow Research Library of The Corning Museum of Glass. Since 1978 she has worked in a variety of positions at the Library and enjoys delving into library resources to help researchers find answers to their questions.

The Corning Museum of Glass’ authority on glass art is felt around the world.


Seminar 4: “The Sound of Breaking Glass”
Presenter: Alexis Clare
Tuesday June 18th – 8:00am – Noon – Hotel, Cohocton

Glass is not just the stuff you make windows or bottles from; it is a sub-state of “solids” where the atomic structure is disordered like a liquid but doesn’t flow like one and is more static like a solid.  Behaviors of glass that make it both supremely useful and extremely challenging have their roots in glass’ non-crystalline atomic structure.  So in principle you can make a “glass” out of any material and we’ll talk about all glass; the kinds you are used to and some that you are not.  We will talk about glass’s behavior; (both good and bad) and about how we can tweak it to behave the way we want! Seminar soundtrack available at!

Dr. Alexis Clare holds a BS in Chemical Physics and a PhD in Physics from the University of Reading UK. Her group is interested Engineering the composition of glass for specific applications. They are also interested in making new and unusual glasses for optical, magnetic and even biological responses. She is also looking at novel ways of processing glasses such as 3D printing and Spark Plasma Sintering.


Seminar 5: “ASGS Oral Histories” & “Looking Back and Moving Forward Panel” (2-part seminar)

Panelists: Ted Bolan, Adolph Gunther, Doni Hatz, Kaite Jones and Ian Pearson
Tuesday June 18th 8:00am – Noon – Hotel
Moderated by Sally Prasch
Oral History Speaker: Brad Turner
This event is free, no registration required

This seminar will address the history of the ASGS organization through the eyes of several individuals who have been a part of it in a variety of capacities. Through dialog with the panelists the conversation will delve into the inception of the organization, how the organization helps its members in their educational and career pursuits, how collaboration within the organization helps support scientific research and the importance of understanding history when looking to the future. In the second half Brad Turner will guide us in how to systematically collect oral histories and learn effective way to preserve our history. Together will will introduce some basic concepts of oral histories, talk about the process and review interviewing skills. We will take turns on doing a short recording section with each other, capturing each others history. We want you to relax, have fun and our goal is that you will not be afraid to record an interview yourself. 

Adolph Gunther was born in Berlin Germany. At age fifteen, he started his apprenticeship (known as Lehrling in Germany) as a scientific glassblower at Osram Industries. His workshop had a total of twenty four students to be invited to join Osram as a research glassblower. At age twenty, he immigrated to Canada and worked as a neon tube bender. Five and a half years later he immigrated to America and worked for Sargent Welsh in Chicago. Six months later he visited Germany and met his future wife Inge. Upon his return to the US he took a job with Fisher Scientific and in 1966 started a glass shop at Stauffer Chemical. Twenty years later, Ted Bolan and Adolf started Advanced Glass Technology that is still in operation today.

Doni Hatz has been captured by glass since she was 19 years old. She holds a degree in Scientific Glass Technology and continues to learn and challenge her skills by attending ASGS events.
