These square murrini show a nested design: a colored center square, often with a smaller contrasting square or diamond at its core, set inside an outer frame. The jar is an assortment. Most slices carry a white outer frame, while a good number have a translucent teal or aqua frame instead. Center colors run across cobalt blue, bright orange, grass green, chartreuse yellow, and teal, so the jar reads as a collection of small geometric color studies.
Murrini, also called millefiori, are small cross-section slices of patterned glass cane. Place individual slices on the surface of a fused glass piece and fire them so they fuse in as geometric color accents on pendants, plates, dishes, suncatchers, and ornaments. These are COE90 murrini; use them only with glass of the same COE.
What pattern do these murrini show? Each slice is a squares-within-squares design: a bright center square in cobalt blue, orange, green, yellow, or teal, frequently with a smaller inner square at the core. Outer frames are white on most slices and translucent teal on others. Colors vary from piece to piece across the assortment.
What glass do I use with these murrini? These are COE90 murrini. Use them only with glass of the same COE. Pairing glass of different coefficients of expansion can cause cracking or delamination as the piece cools.
How are these sold? These are sold by the jar as an assortment of slices. Slice sizes, colors, and counts vary from jar to jar.
How do I use these in a fused glass project? Arrange individual slices on the surface of your COE90 base glass and fire. A full fuse melts them flat and flush with the surface; a tack fuse keeps them slightly raised and holds more of the layered square geometry. They pair well with frit and stringers as part of a larger surface design.
Specifications
SKU: 10794 COE: COE90 Form: jar of assorted slices Pattern: nested square design, assorted center colors with white or translucent teal frames Working Notes
A full fuse melts the slices flat and smooth, so their faces lie level with the surrounding piece. A tack fuse keeps more of the raised, three-dimensional quality and makes the square geometry more pronounced. Both work well depending on the look you want. Fire a small test piece first, since results vary with your kiln and glass, and follow a firing schedule matched to your specific COE90 glass.
