Cast On Castaway

$1,050 MEMBER PRICE: $1,050

with Jacci Delaney

Calendar Next available session starts Jul 20, 2026 at 9 am, runs for 1 week

This five-day introductory kilncasting class will be a tsunami of information and fun experimentation. If you have ever wanted to try glass casting, this is the class for you!

The first day we are going to make our positives with plasticine and fire them. The next day we will start wax working our models. Wax is great because you can make undercuts and just about any other shape. We will then learn the lost wax casting method, steam out the wax and fire the molds.

This class will require any clay or weird household tools that can be used for wax working, thinking outside the box, and willingness to get dirty playing with wax, clay, plaster, and silica.

Please bring three to five small items in any material that you would like to make a casting of, and we’ll see what we can do. The best part will be analyzing the objects you bring to class to see if and how we can cast them in glass. It takes an unusual approach to cast a teddy bear into glass and I bring that to my teaching style.

You will have the choice of free sculpting your models, using ready-made objects, or combining the two in order to execute conceptual ideas, and emphasize your creativity. Shellac can be your best friend when working with soft objects to cast. We will work with alginate and learn how to make rubber molds for multiples. We will also learn how to program the kilns, which can be intimidating but we will conquer it together.

Students are encouraged to use open studio time to work on projects.

Evening Open Studio

Studios are open until 9:30PM for students to practice. Depending on the class, process, and techniques, this time might be highly suggested by instructors for students to use. In other classes, this time might be considered optional.

Deep Relief Dry Plaster Casting

$1,050 MEMBER PRICE: $1,050

with Sean Hennessey

Calendar Next available session starts Aug 3, 2026 at 9 am, runs for 1 week

Discover an easy, versatile, and economical way to create bas relief and deep relief kilnformed glass. Using found objects and fabricated forms, you’ll press originals into plaster powder to create backgrounds and foregrounds, then slump sheet glass into your molds. Working with Tekta Clear Bullseye glass and glass paints, you’ll learn glass cutting, moldmaking, and the kiln schedule for this technique. With minimal coldworking, you’ll use a wet tile saw and wet belt sander to finish your pieces.

This remarkable and nearly waste-free casting method offers endless possibilities for fine art, public art, and architectural applications.

This five-day class is suitable for beginners or experienced glass sculptors, and all skill levels.

Introduction to 3D Print Casting

$540 MEMBER PRICE: $540
Calendar Next available session starts Sep 24, 2026 at 9:30 am
This course introduces the integration of digital fabrication and glass casting processes. Students will learn foundational techniques in 3D scanning, modeling, and printing alongside mold-making strategies for translating digitally produced forms into cast glass objects. Emphasis is placed on material compatibility, mold construction, casting methods for complex three-dimensional forms, and finishing techniques.

As an introductory project, students will scan their own head produce a 3D-printed model, and cast a scaled glass bust, providing a comprehensive overview of the digital-to-glass workflow.

The course welcomes students new to either digital fabrication or glass, as well as those seeking to expand existing studio practices.

Class does not meet the week of October 11-17th, 2026.
