Red Heart Murrini/ Millefiore COE90

Each slice in this bag shows a deep red heart set in a clean white surround. The heart fills most of the face of the slice and reads clearly even on small jewelry work, and the strong contrast between the red center and the white ground keeps the motif crisp whether you scatter slices loosely or line them up in a deliberate row.

Murrini, also called millefiori, are small cross-section slices of patterned glass cane, so every slice in the bag carries the same heart design. Place individual slices face up on the surface of a COE90 fused glass project such as a pendant, dish, suncatcher, or ornament, then fire the piece in your kiln to fuse them into the surface. Sold as a bag of assorted slices; slice sizes and counts vary from pack to pack.

What does the pattern on these murrini look like?
Each slice shows a bold red heart centered on a white field. The white surround forms the outer wall of each slice, so edges read white from the side while the heart appears on every cut face. The clean two-color scheme gives these murrini a graphic character that stays readable at small sizes.

What COE glass must I use with these murrini?
These are COE90 murrini. Combine them only with glass of the same COE. Mixing coefficients of expansion builds stress into the fired piece and can cause cracking, so verify your base glass before firing.

How many slices come in a bag?
These are sold as a bag of assorted slices, and slice sizes and counts vary from pack to pack. The mix of sizes is useful in practice: larger slices carry the heart as a focal accent while smaller ones tuck into borders and detail work.

How do I use these in a fused glass project?
Arrange individual slices on the surface of your prepared COE90 base glass and fire them in your kiln. They are decorative surface accents, not a base layer. A full fuse melts them flat and flush with the surrounding glass, while a tack fuse keeps more of their raised profile.

Working Notes

At a full fuse, these murrini melt flat and smooth into the surface of your piece. The heart stays visible but the edges soften and the surface finishes flush. At a tack fuse, the slices stay raised and the heart keeps a more three-dimensional profile.

The right choice depends on the finish you want and how your specific COE90 glass and kiln behave. Fire a small test piece before committing to a full project, and follow a schedule suited to your glass and equipment.
