Michael Dupille has been teaching art in various capacities since 1975. As a developer of many of the working methods in the kilnformed glass movement, Michael has taught workshops in Mexico and from Ottawa, Canada to Homer, Alaska and numerous locations in the contiguous United States, He also teaches from his home studio in Seattle, WA. 

Michael has been teaching kilnformed glass since the late 1980s, and began working with glass in the 1970s as a glassblower.  He offers classes for all skill levels. Subjects include Fritography, Kiln cast glass, and other specialty techniques such as Scratch n' Frit, Tranchant du Verre (pallete knife glass), and Working with Organic Shapes.

See descriptions and images below for more details.

Michael creates a comfortable and fun learning environment that is supportive and encouraging of all skill levels.

If you are interested in taking a workshop, or hosting a workshop within your local glass community, please e-mail me@michaeldupille.com for details.

Although each workshop has a focus on a particular technique, I always devote a portion of the class to gaining a more concrete understanding on the fundamentals of kiln formed glass.

Nothing is more gratifying for me as an instructor than to see former students succeed with their own work. I also do individual workshops and project consultation.

Aside from group classes, I am frequently asked about private workshops and will be happy to set one up for you if interested.  E-mail me if that is something you’d like to do - me@michaeldupille.com

It’s the time for a new theme for my 2017 Home Studio Experience Workshops.
Due to scheduled commitments I can only offer one in May and one in September.
Enjoy 4 fabulous days of kilnformed glass fun at my home studio in beautiful West Seattle, Washington!


I’ve had a lot of requests for trees and related imagery so we will explore
The Forest for the Trees and delve into all that the title indicates;
landscapes, seasons, leaves, bark, conifer, deciduous  and anything you can dream up that relates to the concept.
We will utilize a myriad of techniques in this exciting 4 day intensive workshop.
Ample one on one time.
Seattle is a beautiful place and I’d love to share it with you.

"I went from being a crafter to being an artist after taking Michael's Studio workshop.  The work went from a few dollar-type pieces to a minimum of $1000..."  Linda K, Sacremento, CA

"Indian Sunset" 2014, Kilnformed glass, 14" h x 20"w




The painterly use of crushed glass frits and powders has opened up a whole new world of artistic imagery. Anything is possible when working with small particle of glass from tight, photo-realism to loose impressionism. Working in the panel format, you will learn how to control color density, shading, soft and hard edge lines and some unique specialty looks. This class will focus on the principles of multiple firing to create a rich, vibrant panel piece. There will be enough studio time to experiment with some technique pieces to assure a greater understanding of the process and how to create a palette. Just imagine how you can expand these techniques to creating unbelievable wall pieces, tiles and continuous murals

When the Frit hits the Fan

This workshop covers a variety of different techniques and processes, and is less focused on imagery.  However, many of the things taught here may be utilized in creating them, including multiple firing. We’ll cover the basic practices of Fritography, combining them with unusual shapes, and use a variety of dam methods.

There are several other ways of working with frit we’ll explore as well; including making ‘Frit Sticks’, ‘Vitrios’, and a new process called ‘Scratch and Frit”.  I think you’ll find these to be useful and fun to do!..and that’s a tough combo to beat!

Tranchant du Verre (Palette knife glass)

The English translation from French roughly means ‘the knife edge of glass’. This unique process is based on traditional palette knife painting using oils or acrylics. 

By using powdered glass with a suspension medium, in this case CMC, similar effects can be created with this technique. These can be altered, added to and embellished using all of what we have in our world of kiln formed glass techniques and processes. The possibilities are unlimited.

Multiple firing using this method gives dimension and richness, depth and vitality to the finished work. This is a really quick, fun and expressive process to create  imagery with glass in ways that were previously in the realm of traditional painting mediums for canvas.
