  • "Kilnworking or kiln forming is the process of fusing or shaping glass (usually in or over a mold) by heating it in a kiln. A 'kiln' is an oven used to process a substance by burning, drying, or heating. In contemporary glassworking, kilns are used to fuse enamel and for kiln-forming processes such as slumping" (Corning Museum of Glass).

    At Foci MCGA, we offer a variety of classes to begin exploring kilnforming through.

    • Kilnforming 1 and Kilnforming 2 focus on fusing and slumping glass.

    • We also offer Open Faced Casting and Lost Wax Casting, which delve into moldmaking, kilncasting, and coldworking.

  • "The generic name for decorative windows made of pieces of colored glass fitted into cames and set in iron frames" (Corning Museum of Glass).

    At Foci MCGA, we explore these processes in our classes Stained Glass 1, Stained Glass 2, and Stained Glass: Working with Lead.

  • Glassblowing is the art of shaping a mass of molten glass that has been softened by heat by blowing air into it through a metal tube/pipe. The molten glass is collected out of a hot furnace and then manipulated using hand tools, heat, and gravity.

    While some elements of heat and gravity may come into play with stained and kilnforming processes, for the most part you will be handling sheets of glass, then manipulating it into desired forms through cutting or fusing. This approach has the ability to be a more accessible and affordable alternative to glassblowing.

    These glass processes all differ from one another, but can be combined in a myriad of ways to create a multitude of wonderful effects!

Glass Kilnforming and Stained Glass Classes


Kilnforming 1

This short introductory course provides an overview of cutting, shaping, and melting sheet glass in a kiln. Through fusing and slumping experiments, participants gain an understanding of how glass reacts to varying temperatures and firing schedules. This class prepares a person for renting Kilns at Foci MCGA and learning the variety of techniques taught in Kilnforming 2. This class will outline several guided projects and test tiles, with the final project being the student’s choice.

No experience required. All materials and tools are provided.

Offered year-round.

4-week course

$375/per person

Foci MCGA kilnforming classes provide Bullseye Glass (COE 90) to students.

Please note that grinders are not utilized in this class.

Open Studio ~ Kilnforming

Come join us for Open Studio in the kiln shop! Make small tests, design, or create new work that will be fired that evening with a mentor present to assist you with your project! Each participant will receive an allotment of glass and space in a kiln for fusing and slumping. Large sheets of glass will be available upon request and based on staff’s discretion. Participants may choose a slump mold for their piece to be slumped in by staff later in the week.

Staff will be responsible for handling and cutting full-sized sheet glass.

3 hour session.

Prerequisite: Kilnforming (Fusing & Slumping 1)

Stained Glass: Working with Lead

In this introductory course, participants will learn how to create a leaded, stained glass panel. Students will learn about selecting, cutting, and grinding glass following a provided pattern of their choice. After which, we’ll move onto assembling the panel using lead came, soldering the joints, and applying a waterproofing putty. Finished projects can become sun catchers or small framed windows for display.

No experience required. All materials are provided.

Offered semiannually.

4-week course

Stained Glass 1

Learn the art of Stained Glass in this introductory course. Participants will select from a variety of beginner patterns to make their projects. We’ll then learn about selecting, cutting and grinding the glass to fit perfectly together. After which we’ll move onto copper foiling the edges and soldering the glass pieces together. Projects will become finished hanging suncatchers or a small framed window to display.

No experience required. All materials are provided.

Offered year-round.

Stained Glass 2

Build on your foundational skills learned in Stained Glass 1 to start designing your own patterns. This 6 week course will expand on the basics by introducing pattern development, creating more complex imagery, sizing up, and refining soldering techniques. Each participant will get to design and build their own 12”x15” stained glass window or wall hanging. 

Prerequisite: Completed Stained Glass 1 or equivalent.

All materials are provided.

Offered semiannually.

6-week course

Lost Wax Casting

The lost wax process allows one to create complex cast glass objects utilizing rubber mold making. Participants learn to create simple and complex rubber molds for creating wax replicas and multiples of found objects as well as modifying and sculpting wax positives from scratch. These wax models are transformed into glass by building plaster/silica molds around them, removing the wax with steam, and casting glass into them. The casting process can be a bit tricky and time consuming - working outside of class time is not required, but highly recommended.

No experience required. All materials are provided.

Offered annually.

6-week course


Kilnforming 2

Add to your fusing and slumping repertoire and expand your kiln knowledge in this intermediate kilnforming course. Learn advanced cutting techniques, how to refine irregular shapes with grinding equipment, create elaborate pattern bars, as well as glass painting, kilncarving, and sandblasting to name a few.

Prerequisite: Completed Kilnforming 1 or equivalent.

All materials are provided.

Offered semiannually.

4-week course
