Class Description:

Learn how to create one of the most mesmerizing optical illusions in glass—the vortex marble. In this medium to advanced-level class, students will dive into the layered world of internal design, depth perception, and precise shaping.

You’ll be guided through the step-by-step process of building a spiral pattern that appears to draw the eye inward, creating the effect of a swirling tunnel in suspended motion. Attention will be given to symmetry, backing the vortex with color or sparkle, and achieving a clean lens-like finish for maximum visual impact.

What You’ll Learn:

• Constructing and shaping internal spiral patterns

• Layering techniques for depth and dimensionality

• Heat control and timing for clean vortex formation

• Backing and finishing for clarity, contrast, and polish
