Each slice in this bag shows a barn swallow caught mid-flight: a cobalt blue bird with swept-back wings and a small golden-yellow accent near the head and body, set against a clean, opaque white ground. The blue dominates the motif and the touch of gold warms it, so the bird reads clearly even on the smaller slices. Thicker pieces resting on their sides in the mix show the pale blue-white banding that runs through the cane.
Murrini, also called millefiori, are small cross-section slices of patterned glass cane. To use them, place individual slices on the surface of your fused glass project and fire them in your kiln. They are decorative accents rather than a base layer, and they work well on jewelry pieces, pendants, plates, dishes, suncatchers, and ornaments. These are COE90 murrini, so combine them only with glass of the same COE.
What does the motif on these murrini look like?
Each slice shows a barn swallow in flight, rendered mostly in cobalt blue with a small golden-yellow accent, on a white background. The pose captures the bird mid-swoop with wings spread, and the design stays recognizable across the size range in the bag.
What COE glass do I need to use with these murrini?
These are COE90 murrini. Fuse them only with glass of the same COE. Mixing coefficients of expansion causes thermal stress and can result in cracking during or after the firing cycle.
How many slices come in a bag?
Sold as a bag of assorted slices; slice sizes and counts vary from pack to pack. The assortment gives you a natural range of accent sizes to work with in a single composition.
How do I incorporate these into a fused glass piece?
Arrange individual slices on the surface of your prepared base glass and fire them in. A full fuse will melt the murrini down flat and flush with the surface for a smooth, integrated look. A tack fuse stops before full collapse and leaves the slices with more of their raised, dimensional character. Run a small test piece first and choose the schedule that suits your glass, kiln, and intended result.

Working Notes
A full fuse brings the murrini completely level with the surrounding glass, blending the swallow image smoothly into the surface of the piece. If you want the slices to retain more of their original raised profile, a tack fuse at a lower peak temperature is the right approach.
In either case, fire a small test tile before committing to a full project, and match your ramp, peak, and hold to the specific glass formula and kiln you are using.
