Intermediate level.

You’ll be introduced to the endless design possibilities when you “carve” shapes into the back surface of glass using a variety of fiber materials in this two-day class. These materials, in turn, lead to vastly different surface results. This is a wonderful method to create glass panels with incredibly detailed contours that catch, bend and reflect the light. It’s a simple technique that can produce a complex, sculptural look in your work.

In this two-day class we’ll introduce you to the techniques with lectures and demonstrations, including information about which glass styles work best and the importance of correct firing temperatures. You’ll create a set of samples with multi-layered designs.  After firing, we’ll discuss the results of each set of samples. With this new knowledge you’ll have the opportunity on the second day to design and create a larger pair of kilncarved panels.

Tuition includes all glass and materials for the completion of the projects.  Glass cutting skills are helpful but not necessary.

Saturday & Sunday, 10-4 each day
Tuition $375 - Deposit $200
Intermediate level.

In this unique class we will reexamine this time-honored glass construction process pioneered by Klaus Moje, the father of contemporary kiln glass. Pushing the limits of what we know as strip cut construction, we will explore what happens when variables are altered.

Choosing from Vitrum Studio’s extensive library of samples for this class, we will explore and research design possibilities through sample making.  On the first day, each student will create a variety of samples. Then, as a group, the class will examine the results of each of those samples after firing. These carefully analyzed results will inform the design of the final larger project on the second day.




NEW BLOC Classes!

Vitrum Studio has been fortunate over the past 15 years to have had a wide range of incredibly talented artists teach advanced courses for us. Through their generous sharing of the techniques each has discovered and developed through their personal experiments, and our own research and experiments based on some of these techniques, we now have an almost fool-proof way for firing a thick block to a polished finish. We will debut and share this technique the OpticBLOCS and MiniBLOCS workshops.

WOW! The first samples that came out of the kilns as this class was being developed caused a standing ovation from our staff artists. Yep, they are that amazing.(and our artists are, too!)

A thick, free-standing optically-distorting block project that requires almost no hand-polishing?  Yes. And we’ll show you two ways to do it.

You’ve all admired the thick little block on display during our Optic Topics class, and you’ve certainly made no secret of wanting to take a class to learn how to make it. Well, this is the class for you.

In this three-day workshop, the third in the uniquely Vitrum series of Optic Topics, students will further experiment with the optic distortions caused by intentionally disturbing a regular pattern of lines. We will combine several layers of distorted patterns in a thick block that further physically and visually distorts what the viewer perceives.

We’ll design several projects that will take advantage of optical distortions and that are further enhanced by being inserted within a thick block. You’ll learn how to correctly dam and fire the thick composition, and will also learn two different methods for creating a block that requires little coldworking to be gallery-ready.

Saturday & Sunday, 10-4 each day
Tuition $375 - Deposit $200
Intermediate level.

This is the second in a series of classes that reinterprets one of the basic construction techniques in the kiln former’s arsenal – strip set on edge, then dammed and fired.  Radially arranging strips of glass is a versatile play on this time-honored way of working, and is suitable for creating designs that range from precise and formal to loose and organic.  Using this method of construction, precisely symmetrical patterns reminiscent of the Art Deco period are just as achievable as naturalistic branching structures.  

Choosing from Vitrum Studio’s extensive library of samples for this class, we will explore and research design possibilities through sample making.  On the first day, each student will create a variety of samples. Then, as a group, the class will examine the results of each sample after firing. These carefully analyzed results will inform the design of the final larger project on the second day.

A New Perspective: MiniBLOCS

In this three-day class, the third in the uniquely Vitrum Series of Miniature Landscapes, (are you seeing a pattern here.?!), students will experiment with and learn to create effective and display-ready miniature landscapes that can either be a free-standing thick block or a wall-hung panel.

In the free-standing block project a thick clear glass block covers and enhances the delicate landscape composition it protects.  After a little coldworking on its four sides, it goes back into the kiln for a special firing that creates the look of a hand-polished finish without all the labor.

A second new approach creates a unique framed effect around a miniature image.  The scene is enhanced when surrounded by the resulting “frosted” frame. And the piece is almost gallery-ready for hanging when it leaves the kiln after one firing.

Through lecture, demonstration and samples, each student will be guided step-by-step through the basic processes.  Students will then have ample time to design and create their own pieces, perhaps displaying environments that are special to them.

Firing schedules and display options on the third day complete the class.




Visiting Artist Alice Gebhart

Alice Benvie Gebhart specializes in brightly colored landscapes in unique palettes that are created with layers of richly colored sheet glass and powder and then enhanced with traditional glass paints. This workshop will cover her processes, both instinctive and practical, in creating compositions with depth, perspective and unusual color schemes.

Alice, a longtime landscape artist and instructor who maintains a gallery and studio in Rhode Island, has created with glass since 1995 and has developed her own techniques and distinctive style in her kilnformed glass work that reflects her painting background.

This class is full, but a wait list is available.

April 9, 10 & 11, 2016
Sat., Sun., & Mon. 10-4 each day

Tuition $650 - Deposit $325
Intermediate to Advanced level.


In this three-day workshop, students will be introduced to Alice’s process in creating her colorful landscapes. Lecture topics each day will include translating sketches into glass compositions, underpainting and finding light, and highlighting mood in your work. Students will make several samples and design  two 6” x 8” wall pieces, a landscape and a seascape, as they are introduced to Alice’s unique techniques. 

On the last day, Alice will also demonstrate her techniques for presenting work in a way that preserves the transparency of glass.

The DEBUT of a NEW Class!

This course is a comprehensive approach to the painterly layered landscapes that Alice creates in kiln formed  glass and is the ideal ”next step” for those who have taken her first class.

With two complex companion landscapes as the final project, students will develop   landscape designs through sketches and comprehensive sample-making. Using both new and time-honored techniques, students will create layered landscapes of glass that are reviewed, critiqued and further developed through both additive and subtractive techniques, multiple firings and shapings. The addition of details and highlights with fired on Color Line paints and 24K gold paints complete the pair.

Lectures and presentations will cover Alice’s methods of creating work using multiple, cohesive color schemes. The techniques of using a view finder, developing sketches from photos, “under painting”, correcting your composition, and how to use various types of books for texture references will be also be discussed.

NEW Class!

What fun! Here’s your chance to pull twisted cane at the Vitrigraph, make your own vitrigraph pot in the colors you like with a partner AND then make a final project with your cane creations, all in a two-day class!

On the first day, you’ll explore various ways of pulling and twisting your canes for various effects, and each student will share the canes pulled from 5 different pots. Then we’ll demonstrate how to load your vitrigraph pot for the maximum color separation and contrast, and you and a partner will choose your favorite colors from those available and actually design your own pot.  The next morning you will pull the twisted canes from your vitrigraph, giving you a wide variety of canes to choose from to use for your final project and the extra twisties are yours to take home and use in other projects!




April 30 & May 1, 2016
Saturday & Sunday 10-4 each day
Tuition $295 - Deposit $150
Beginner level.

This two-day introductory workshop is designed with the beginner in mind and will guide you through an exploration of the possibilities of fused and slumped glass. We will demonstrate the basics of glass cutting, demystify the kiln and its controller, explain the various steps of a firing schedule and discuss the importance of glass compatibility and annealing. You will be able to experiment with design possibilities using a wide variety of frit, stringers, confetti, sheet glass and iridized glass in the Bullseye Glass palette.

During the class you will create a set of example tiles, a thick color study tile and two fused and slumped bowls. Our goal is to introduce you to both the technical and artistic side of the medium of kilnformed glass. Tuition includes all materials and the use of basic tools, and is a prerequisite for most of our other classes.
