COE90 Glass Circles

Cutting a clean glass circle by hand is one of the hardest skills in glasswork, and these precut circles skip that step entirely. This category offers precut glass circles and rounds cut from COE90 fusible glass, including opalescent colors, clear, iridescent, and dichroic coated circles, ready for fusing, mosaics, stained glass accents, and craft projects.

What's in this category at AGS

• Opalescent circles in colors such as Black, White, Red, Orange, Egyptian Blue, Lilac Purple, Spring Green, Canary Yellow, and Ivory
• Clear and clear iridescent circles for caps, bases, and suncatchers
• Dichroic glass circles on clear or black glass in finishes like Candy Apple Red, Emerald Green, Cyan/ Copper, Silver, and Rainbow

Choosing sizes and colors

Many colors are offered in several diameters, from 1/2 inch up to 3.6 inches, so you can buy exactly the size a design calls for. Small rounds work well as jewelry blanks, eyes, and dot accents, while larger circles suit coasters, plates, and layered bowl designs. The dichroic circles on black glass give the boldest color flash, and the versions on clear stay translucent when light passes through.

Usage notes

These circles are cut from 3mm COE90 glass and fuse reliably with Bullseye and other COE90 compatible glass. They also work as colored glass discs for mosaics and general craft use where no firing is involved. For kiln projects, keep everything in the piece within the COE90 system rather than mixing with COE96.
