Each slice is cut square and shows a jewel like nested design: translucent red orange glass surrounding a crisp white square frame, with a small warm center inside the white ring. Light passes through the red orange areas, so the slices read bright over lighter base glass and rich and deep over dark. The clean geometry stays legible across the range of slice sizes.
Murrini, also called millefiori, are small cross-section slices of patterned glass cane. Arrange individual slices on the surface of a COE90 fused glass project, such as a pendant, plate, suncatcher, or ornament, then fire them in your kiln so they fuse into the base glass as decorative accents.
What pattern do these murrini show? Nested squares: translucent red orange glass around a white square frame with a small warm center. The consistent geometry works wherever you want a structured, repeating accent.
What COE glass should I use with these? These are COE90 murrini. Use them only with glass of the same COE. Mixing expansion rates introduces stress as the piece cools, which can lead to cracking.
How many slices come in a jar? Sold as a jar of assorted slices; sizes and counts vary from pack to pack. All slices share the square cut even as widths vary.
How do I use murrini in a fused glass project? Arrange individual slices on the surface of your prepared COE90 base glass and press them lightly so they hold position, then fire to your standard COE90 schedule.
Specifications
SKU: 162126 COE: COE90 Packaging: jar of assorted slices; sizes and counts vary Pattern: nested squares in translucent red orange with a white square frame; square cut slices Working Notes
A full fuse melts these slices flat and flush into the base glass, so the pattern reads as an inlaid detail. A tack fuse, run to a lower peak, keeps more of each slice's raised shape and surface texture.
Because kiln behavior varies with equipment, glass thickness, and layout, fire a small test piece before a full project and match your schedule to your kiln and COE90 base glass.
