Marble Making Fundamentals with Andrew Certo

Step into the world of flameworking and discover the art of glass marbles using borosilicate glass. In this hands-on introductory course, students will explore a range of foundational techniques while creating a diverse collection of finished pieces. You’ll learn how to confidently shape solid glass, apply vibrant color, and execute core processes such as implosions, encasements, and twists.

By the end, you’ll leave with a solid understanding of marble-making processes—and a set of unique, hand-crafted marbles that showcase your progress.

Additional work time for intensive students: Students will also have access to additional hours in the flame shop, without instruction, on Wednesday - Saturday from 12-4pm. Students must be able to work safely in the studio, and be able to set up their area without needing instruction. Students participating in student hours will need to be approved by the instructor and TA’s.

What to expect:  Flameworking with borosilicate glass requires a little practice at heat control with the torch to create successful sculptures. After demonstrations, students will have time on the torch to hone their skills. Clean-up time is included in the duration of class, and usually the last 20 minutes of class are dedicated to cleaning your workstation. Read more about how to prepare for class on our Registration Info page. 

While flameworking, participants primarily engage in seated activities such as working with glass rods and torches. The environment can be bright and loud at times. Handling glass and tools may require a certain level of dexterity. To learn more about accessibility the Accessibility page on our website.

Eligibility: No experience needed,  open to all levels. Open to ages 14 and up. 

Pick-up: The glass needs to cool down overnight, so the students will have to return to UrbanGlass once notified to pick up their work. 

We recommend registering for classes early to reserve your spot! We base materials, and teacher needs off of student enrollment.
