What Is Kiln-Glass?

Kiln-glass is just that: glass formed in a kiln.

Kiln-glass (or kilnformed glass) objects are made with glasses tested as compatible for fusing when heated in a kiln. Tested compatible glasses were developed and are manufactured by Bullseye Glass Co. in a variety of forms and in a sophisticated palette of colors. Once assembled as desired and heated in a kiln, the glasses soften, fuse together, and assume the shape of whatever surface they're resting upon or within, such as a flat kiln shelf, curved mold, or casting mold.

The range of kiln-glass objects one can make involves a range of techniques. Most people start by making small, flat objects like coasters and tiles. From these simple forms, they move on to curved plates, platters, and bowls. And some go further still, exploring more complex techniques and focusing on the fine arts and architectural potential of kiln-glass.

Kiln-glass is especially rich territory for artists because it encompasses an enormous range of working methods, from drawing and painting, to printmaking, to sculpture and more. Artists already have many of the skills required for kiln-glass: an understanding of design, composition, and color theory, and an ability to conceive of layers of process and material application.

While kiln-glass does require a basic knowledge of technical issues and nuances, these are readily obtained in short order through Bullseye classes, online videos, and technical articles that have been developed as an outgrowth of our years of collaboration with artists. Numerous colleges and universities worldwide now offer kiln-glass programs, and many communities have kiln-glass studios or centers where instructors teach classes, sell glass, and make rental kilns available to those who are learning.

Bullseye kiln-glass is manufactured by hand in our factory in Portland, Oregon.
