Hotel Reservation

Registration Form (PDF)

COURSE DESCRIPTION:

This course is an intensive combination of classroom lectures and laboratory exercises that address most of the significant properties of glass, both theoretically and experimentally. The individual sessions are titled in the accompanying outline of the daily topics. The lectures are organized to define each property, examine thermal and compositional effects, and describe practical measurement techniques. The laboratory sessions are designed to give the participants experience with common glass property tests.

WHO WILL BENEFIT FROM THIS COURSE?

Engineers, managers, contractors, purchasing agents, furnace operators, maintenance supervisors, and technicians who are involved in the manufacturing, marketing, research and development, or consumption of glasses will find this course beneficial. A high level technical or engineering background is not essential to take this course, although technical professionals will find the subject matter informative and useful.

COURSE OBJECTIVES:

The lectures of this course are designed to introduce the participants to the ceramic engineering fundamentals of glass properties. The laboratory sessions are designed to provide the participants with direct experience in fabricating test specimens and the application of standard ASTM test methods.
