Each slice in this jar shows a small chickadee softly rendered in black and warm amber brown on a clean white ground. The dark head and wing sit above a gentle amber breast, and the generous white field around the bird keeps the motif easy to read at fusing scale. The subdued palette suits nature themed, wildlife, and seasonal fused glass work.
Murrini, also called millefiori, are small cross-section slices of patterned glass cane. The pattern runs the full length of the cane, so every slice reveals the same chickadee design. Place individual slices on the surface of a COE90 fused glass piece before firing and they fuse in as decorative accents. They work well on pendants, small plates, suncatchers, ornaments, and decorative dishes.
What does the pattern on these murrini look like? Each round slice shows a chickadee with a dark head and wing and a warm amber brown breast, set against a white ground. The rendering is soft edged rather than sharply outlined, which gives the bird a painterly quality, and it pairs naturally with other nature inspired elements in a fused glass composition.
What COE glass should I use with these murrini? These are COE90 murrini. Use them only with glass of the same COE. Mixing expansion rates causes thermal stress that can crack the finished piece during firing or cooling, so keep these in a COE90 only workflow.
How many slices come in a jar? Sold as a jar of assorted slices; slice sizes and counts vary from pack to pack. Sizes within the jar vary as well, which helps when composing groups at different scales.
How do I use these slices in a fused glass project? Arrange individual slices face up on the surface of your prepared COE90 glass before firing. They are surface accents placed on top of a base layer, not a casting material. Position them where you want the chickadee motif to appear, then fire according to your chosen schedule. See the Working Notes below for guidance on full fuse versus tack fuse results.
Specifications
SKU: 13960 COE: COE90 Packaging: jar of assorted slices; sizes and counts vary Pattern: chickadee in black and warm amber brown on a white ground Working Notes
A full fuse will melt these murrini flat and flush into the surface of your piece, blending the edges smoothly into the surrounding glass. A tack fuse keeps more of the raised, three dimensional profile of each slice, preserving a bit of texture and depth. Neither is universally correct: the result depends on your kiln, your specific COE90 glass, and the look you are after.
Always test a small sample piece before committing to a full project run. Match your firing schedule to your materials and kiln rather than following a single fixed schedule, and keep every component of the piece at the same COE to avoid stress during thermal cycling.
