Class, No Prerequisite

Glass Arts Studio

Fused Glass


Provide glass with an opportunity to move and it will. Contain it in a box on an incline, and you'll form a three-dimensional glass wedge within which one can witness the suspended flow. These palm-size wedges make great three-dimensional paperweights, sun catchers, or simply light/color sculptures that absolutely stand out in any environment except for a dark room. 

Given their shape, they're super stable on their own without a stand or base to distract from the beauty within. They can be produced in smaller/shallow kilns and the process also can be scaled for larger kilns and projects.

Over four days, you'll see and learn everything from making the (reusable) mold to putting on the finishing touches in the cold shop. Across multiple firings, projects will incorporate sheet, frit and murrine.


You'll load and finish two wedges and own the molds you used in class when it’s over.


A materials fee of $175, included in the registration fee, covers all the materials you'll need during class (sheet glass, frit, murrine, and mould materials).


All are welcome, the only prerequisites are the ability to cut sheet-glass and a willingness to experiment, learn, be challenged, and have a bit of fun doing it.

Nathan Sandberg

An artist and educator based in Portland, Ore., Nathan worked in the Research and Education department at Bullseye Glass Co. for eight years and has established himself as one of the top kiln-glass educators teaching today.
From Santa Fe to Zurich and Australia to Norway, Nathan is usually somewhere on the planet presenting fresh, innovative curriculum at a wide range of studios, schools, and art centers. He's widely credited as the pioneer of the modern Vitrigraph methods, which he began to develop at Bullseye in 2009 and which have become one of his primary methods for creating work.
He opened OnGrade Studio in North Portland in 2015 where he produces work for exhibitions and develops new curriculum to teach. His primary material is glass, although his installations commonly use other materials such as wood, metal, and concrete. His work can be found in private and public collections around the world.
