Pattern Bar: Segment Slab L039

A segment slab is a multicolored glass block used in one approach to the pattern bar technique. The segment slab is composed of sheet glass strips that are tack-fused together, cut into parts, and fired within a containment system until the glass flows and forms an internal pattern.

This fun and easy project-based lesson models how to create a segment slab. It then details how to cut it into cross-sectional pieces and reveal its internal pattern. Finally, it demonstrates how to use the cross-sectional pieces to design and make a finished work.
