Casting

in Type of Glassmaking

Introduction to Casting

$540 MEMBER PRICE: $540
Calendar Next available session starts Jan 21, 2026 at 9:30 am, runs for 8 weeks
Combine sculpting and moldmaking with the heat of the kiln to create cast glass sculptures. Begin by learning the basics of kiln cast glass by creating small 3D objects then move on to making glass replicas of found objects. Explore silicones and other moldmaking materials and learn the lost wax casting process. Finally, you'll work with body-safe life-casting alginate and take a mold of your hand (or other body part) and turn it into glass. This class will cover model construction, refractory molds, glass preparation, firing, and resolving castings into finished works of art. No experience necessary.

Class does not meet on 3/4.

Ages 14+

Kiln 1: Fusing and Casting

$540 MEMBER PRICE: $540
Calendar Next available session starts Jan 22, 2026 at 9:30 am, runs for 8 weeks
Are you curious about the kiln Shop? In Kiln 1, you will gain a broad understanding of the vast possibilities of kilnformed glass exploring both fusing and casting techniques. You will learn how to cut sheet glass and work with a variety of other materials to melt and shape your designs creating an array of functional and decorative pieces. Then get a bit more dimensional with an introduction to cast glass. Using a found object, you will learn how to reproduce the object in glass. You will also gain an understanding of kiln programming and the properties of glass. No experience is necessary.

Class does not meet on 3/5.

Ages 14+

3D Multiple Layers Fusing

$950 MEMBER PRICE: $950

with Emma Varga

Calendar Next available session starts Jun 22, 2026 at 9 am, runs for 1 week

During this class, Emma will introduce her original method of fusing and casting multiple layers of glass, which she has been exploring and developing, with great success, for past 20 years. This innovative technique enables fusing/casting of thin glass sheets used to set up layers composed of tiny mosaic-like elements, thus achieving three-dimensional images inside the transparent fused/cast sculptural object.

This class will focus on a new way of three-dimensional thinking in creating glass objects; on using properties of glass to achieve visual effects as well as to achieve a sense of movement within cast glass objects. You are not required to have previous experience in glass fusing. Beginners will be able, along with students possessing advanced glass fusing skills, to create and finalize their own three-dimensional glass objects during this class. Additionally, you will receive basic information about grinding and polishing three-dimensional glass objects. At all times, students will have access to an extensive digital gallery in Emma’s laptop including images of recent work as well as closeups revealing fine details on layers inside the glass object. Expect to discover an exciting new method of creating images within transparent three-dimensional glass objects.

In the past 10 years, Emma experimented with new techniques such as glass mosaics made from pre-fused elements, as well as sculptural objects constructed from tiny pâte de verre elements - a rather unusual and innovative application of pâte de verre technique. Another field of experimentation is using pâte de verre elements for inclusion onto layers of fused/cast objects. During her class, Emma will demonstrate and explain these methods, as well as vast possibilities and combinations. Students will be encouraged to experiment and play with kilnforming techniques in order to create a range of small fused, cast objects.

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.

Cast On Castaway

$950 MEMBER PRICE: $950

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

$950 MEMBER PRICE: $950

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.

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.
