Each slice shows a solid cobalt blue butterfly with wings spread wide, centered on a frosted white and clear round ground. The bold silhouette reads clearly across the range of sizes in the pack, and the same butterfly appears on every slice, giving a fused glass project a coordinated look.
Murrini, also called millefiori, are small cross-section slices of patterned glass cane. Place individual slices on the surface of a COE90 fused glass project such as a pendant, plate, dish, suncatcher, or ornament, then fire them so they fuse into the surface as decorative accents.
What does the pattern look like? Each slice carries a cobalt blue butterfly with open wings set against a frosted white and clear background. The deep blue against the pale translucent ground keeps the motif distinct and easy to read even at small sizes.
What glass should I use with these murrini? These are COE90 murrini. Combine them only with glass of the same COE. Mixing glass of different expansion rates creates stress that can cause cracking during or after firing.
How is this sold? It is sold by weight as a pack of loose murrini slices. The exact slice count and the mix of slice sizes vary from pack to pack.
How do I use these in a fused glass project? Arrange individual slices on the surface of your COE90 base glass before firing. A full fuse melts them flat and flush into the surface for a smooth, inlaid look. A tack fuse stops short of that, leaving each slice slightly raised so the motif keeps more of its three-dimensional character.
Specifications
SKU: 10700 COE: COE90 Format: loose murrini slices, sold by weight (count and slice size vary from pack to pack) Pattern/motif: cobalt blue butterfly on a frosted white and clear ground Working Notes
A full fuse melts these murrini flat and flush into the base glass so the motif sits embedded in a smooth surface. A tack fuse preserves more of the raised profile, leaving the slices slightly proud of the surrounding glass. Both approaches are valid, and the right choice depends on the finished look you want.
Always fire a small test piece before committing to a full project. Results vary with kiln, glass thickness, and firing schedule, so match your schedule to your own materials and equipment rather than to any generic guideline.
