Liquid leading creates the raised outlines that define stained glass designs, those dark lines that separate color fields and provide structure. Gallery Glass Liquid Leading flows through precision applicator tips to produce consistent, dimensional borders on glass, acrylic, mirrors, and other non-porous surfaces. The self-leveling formula smooths as it dries, eliminating application marks while building actual relief that mimics traditional came channels.

Black creates classic leaded glass appearance; gold delivers a warmer, more decorative effect. Water-based formulation cleans up easily during application and remains non-toxic throughout the process, making it appropriate for family projects and classroom use. Once cured, the dimensional lines stay flexible rather than cracking when the underlying surface expands or contracts with temperature changes.

Apply leading first to establish your design framework, then fill sections with Gallery Glass Window Color paints once borders have set. The raised lines contain flowing paint and prevent colors from bleeding together, essential for maintaining crisp edges between adjacent sections. Works equally well for traditional stained glass patterns and contemporary geometric designs.
