Black and White Skull Murrini/ Millefiore COE90

Each slice in this jar shows a skull face in bold black and white. A solid black outer ring frames a white ground, and the skull reads clearly against it: hollow eye sockets, an open nasal cavity, and the rounded dome of the cranium. The high contrast between the deep black border and the bright white face keeps the motif legible even on the smallest slices, and a few pieces in any scoop sit edge on, showing the glossy black side of the cane instead of the face.

Murrini, also called millefiori, are small cross-section slices of patterned glass cane. To use them, arrange individual slices on the surface of your COE90 fused glass project and fire them in your kiln so they fuse permanently into the piece. The skull motif works as a detailed accent on pendants, plates, ornaments, suncatchers, and decorative dishes, and suits Halloween and Day of the Dead themes especially well.

What does the skull design look like on each slice?
Each round slice carries a black outer ring framing a white ground. On that white ground the skull face appears: two hollow eye sockets, an open nasal cavity, and the rounded cranium. The design is crisp and high contrast, so it reads clearly at typical murrini sizes.

What COE glass must I use with these murrini?
These are COE90 murrini. Combine them only with glass of the same COE. Mixing glass with mismatched expansion rates introduces thermal stress that can crack or shatter a piece during or after firing.

How many slices come in a jar?
Sold as a jar of assorted slices; slice sizes and counts vary from jar to jar. Jars weighted toward smaller slices hold more pieces, while larger slices mean fewer per jar.

How do I use skull murrini in a fused glass project?
Arrange individual slices skull face up on the surface of your prepared COE90 glass, positioning each one where you want a detail accent. Fire the piece using a schedule suited to your glass and kiln. The slices bond to the surface and become a permanent part of the finished piece.

Working Notes

A full fuse will melt these skull slices flat and flush into your glass surface, integrating the motif smoothly with the surrounding piece. A tack fuse stops short of full melting and preserves more of the raised, three-dimensional character of each slice, so the skull details stand slightly proud of the surface.

Test a small sample before committing your full project, and adjust your firing schedule to match your specific glass, kiln, and target outcome. No single temperature profile works for every setup.
