Each slice in this jar shows a miniature baseball: a white circular field crossed by two curved red stitching lines, all framed by a solid black outer border ring. The contrast between the white center, the vivid red seam lines, and the dark surround keeps the motif sharp and recognizable even at murrini scale, a natural accent for sports-themed fused glass work or any piece that calls for a bold, graphic detail.
Murrini, also called millefiori, are small cross-section slices of patterned glass cane, and the pattern runs the full length of the cane, so every slice reveals the same baseball image. Place individual slices flat on the surface of a prepared piece and fire them in as decorative accents on jewelry, pendants, plates, dishes, suncatchers, and ornaments.
What COE glass must I use with these? These are COE90 murrini. Use them only with glass of the same COE. Combining glass with different coefficients of expansion introduces stress that can cause cracking or delamination as the piece heats and cools.
How many slices come in a jar? Sold as a jar of assorted slices; slice sizes and counts vary from pack to pack, so treat each jar as a mixed assortment rather than a fixed count.
How do I use murrini in a fused glass project? Arrange individual slices on the surface of your COE90 glass before loading the kiln. A full fuse brings them flat and level with the surrounding glass for a smooth finish; a tack fuse stops short, leaving the slices with more of their raised, rounded profile. Test a small sample piece first and match your schedule to your specific glass, kiln, and desired result.
Specifications
SKU: 162118 COE: COE90 Format: jar of assorted slices; slice sizes and counts vary from pack to pack Pattern/motif: baseball, white field with curved red stitching lines and a black border ring Working Notes
Always fire a small test piece before committing to a full project. Kilns, glass brands, and piece thicknesses all affect how murrini behave at temperature, so work from your glass manufacturer's recommended COE90 fusing schedule and adjust from there rather than following a generic ramp rate or hold time.
