Sign Up for Hollow Functional Glass Art Classes at Delphi Glass!

Everything Else

Take your flameworking skills to the next level with Delphi Glass. We’re excited to offer classes that teach you how to create hollow functional glass art. Hollow functional glass art involves the creation of different vessels that you can use in different ways. In these classes, you’ll become familiar with using Borosilicate glass, COE 33, to design your own unique hollow glass art creations including cups, shot glasses, vases, and pipes.


Instructor Val Oswalt-De Waard shows you how to become a master at this technique. You’ll learn how to use basic borosilicate tubing techniques to heat and shape hollow forms into functioning glass sculptures. See it done and then get a hands-on experience to blow hollow forms, open cups and flame open-air holes. You’ll also learn how to introduce some color into these hollow forms.


One-day classes on hollow functional glass art allow for enough time for every attendee to have the chance to make a shot glass, a hollow pendant, and two pipes. If you have some experience with flameworking, this is an amazing class to help you grow and expand your skill set. However, if you’ve never done flameworking before, we advise you to take a more basic class first in order to cultivate your skills.
