Spider Murrini/ Millefiore COE90

Each patterned slice in this jar carries a solid black spider silhouette set against a vivid chartreuse green background. The spider reads as a compact rounded body with legs radiating outward, a clean graphic shape that stays legible even at small sizes. A few solid chartreuse pieces appear in the mix where the cane shows edge on.

Murrini, also called millefiori, are small cross-section slices of patterned glass cane, and every patterned slice carries the same image on its face. Rated COE90, they are placed on the surface of a fused glass project and fired in, adding color and motif to jewelry, plates, suncatchers, dishes, and ornaments.

What does the motif on these murrini look like?
A solid black spider with a rounded body and outstretched legs on a bright chartreuse yellow green ground. The high contrast keeps the image sharp in the finished piece, which makes these a natural fit for Halloween work.

What glass do I need to fuse these with?
These murrini are COE90. Combine them only with glass of the same COE. Mixing coefficients of expansion builds stress into the piece and can cause cracking during or after firing.

How many slices come in a pack?
Sold as a jar of assorted slices; slice sizes and counts vary from pack to pack. The mix of smaller and larger slices gives you fine detail accents and focal pieces from the same jar.

How do I use these in a fused glass project?
Arrange individual slices pattern side up on the surface of your base glass, then fire. They are surface accents, not a base layer, so a single spider slice can anchor a composition as a focal point or repeat as scattered detail across Halloween ornaments, pendants, plates, and suncatchers.

Working Notes

A full fuse melts the slices flat and flush with the surrounding glass for a smooth, integrated surface. A tack fuse stops at a lower peak, leaving the slices slightly raised with more defined edges and a subtle dimensional profile. Choose based on the finish you want for the piece.

Fire a small test piece before committing to a full project. Kiln behavior, glass thickness, and layout all shift results, so let your own test confirm the schedule for your COE90 glass.
