Deep Relief Dry Plaster Casting

with Sean Hennessey

$950 MEMBER PRICE: $950

Discover an easy, versatile, and economical way to create bas relief and deep relief kilnformed glass. Using found objects and fabricated forms, you’ll press originals into plaster powder to create backgrounds and foregrounds, then slump sheet glass into your molds. Working with Tekta Clear Bullseye glass and glass paints, you’ll learn glass cutting, moldmaking, and the kiln schedule for this technique. With minimal coldworking, you’ll use a wet tile saw and wet belt sander to finish your pieces.

This remarkable and nearly waste-free casting method offers endless possibilities for fine art, public art, and architectural applications.

This five-day class is suitable for beginners or experienced glass sculptors, and all skill levels.

Evening Open Studio

Studios are open until 9:30PM for students to practice. Depending on the class, process, and techniques, this time might be highly suggested by instructors for students to use. In other classes, this time might be considered optional.
