COE90 Frit Balls

COE90 frit balls are small, pre-rounded glass spheres used to add raised dot accents to fused glass work. This category at Art Glass Supplies is built around G. A. G. frit balls in a deep palette of transparent, opalescent, and striker colors, all formulated to fire at COE90 alongside other 90 expansion glasses.

What COE90 frit balls are

Frit balls are individual rounded beads of fusing glass, intended for placement as decorative dots rather than scattered like loose frit. Because they hold their shape through a tack or contour fuse, they sit proud on the surface of the base glass and read as crisp, raised points instead of spreading puddles.

Colors and finishes in this category

The G. A. G. range here spans transparents like Aquamarine Blue, Deep Plum, Marigold Yellow, and True Blue, opalescents from Black, Canary Yellow, Cobalt Blue, and Jade Green through Pink, Pea Pod, and Turquoise, plus striker and tint colors such as Burnt Scarlet, Ruby Red, and Plum Striker that develop their final hue during firing. Neutrals like French Vanilla, Deco Gray, and Butterscotch round out the palette for skin tones and earth themes.

Choosing for COE compatibility

Every frit ball in this category is COE90, so they pair with Bullseye and other 90 expansion sheet glass, frit, stringers, and powders with reduced compatibility risk when the rest of the project is tested-compatible COE90 glass and the firing schedule is appropriate. They are not interchangeable with COE96 systems, so keep each project to a single COE family. If you also work in matching powders, fine, medium, or coarse grades, browse the broader COE90 Frit parent category.

Firing and placement

Frit balls are typically set onto the cold base with a small dot of fusing glue, then taken through a tack or contour fuse schedule so they bond but keep their round profile. A full fuse will flatten them into discs, which is sometimes the goal for eye dots or polka-dot patterns. Striker and tint colors will look pale or off in the jar and reach their true color only after firing, so test fire a sample before committing to a large piece.

Common uses

Makers reach for COE90 frit balls for eyes on fused glass animals and characters, raised centers on flowers, dot accents in jewelry pendants and cabochons, repeating motifs in pattern bars, and tactile texture across plates, tiles, suncatchers, and ornaments. Because each ball is consistent in shape, they also work well anywhere matched dot size matters across a series.
