Sign up for a glassblowing workshop, today! 

The Science & Art of Glassblowing Class, Spring 2023

Led by our master scientific glassblower Sally Prasch, this course is primarily for students interested in glassblowing. History of glass will be covered as well as the different compositions, safety, and uses. Students will learn how to form glass in a flame. There are many types of glass and glass parts manufactured, and we will go over what types are best used for different functions. Using a small flame, glass tubing, and rod, students will also learn how to design and create their own pieces. We will go over how to construct strength into pieces and this will increase safety. We will also go over the history of glassblowing to give a better knowledge of where we have been and where we are going. This is a 1 credit pass/fail course with a lab fee of $95. 

Register today! NATSCI 690G The Science of Glassblowing. Fridays 10:10-11:00 a.m. or Thursdays 9:30 - 10:20 a.m.
