Blue Fish Murrini/ Millefiore COE90

Each slice in this jar carries a small fish motif in deep blue, set within a warm amber and golden yellow surround and finished with a clear glass outer border. The dark fish silhouette reads crisply against the bright golden ground, giving each piece strong contrast and a lively aquatic character that holds up even at the smallest slice sizes.

Murrini, also called millefiori, are small cross-section slices of patterned glass cane, so every slice shows the same fish image. These are COE90 murrini for use as decorative accents in fused glass work: place individual slices on the surface of a project and fire them in. Sold as a jar of assorted slices; slice sizes and counts vary from pack to pack.

What does the motif on these murrini look like?
Each slice shows a compact fish shape in deep blue, surrounded by a warm amber and golden yellow field and bordered by a clear outer ring. The contrast between the dark fish and the golden ground makes the image easy to read even in the smaller slices.

What COE glass do these murrini require?
These are COE90 murrini. Combine them only with glass of the same COE. Mixing coefficients of expansion introduces thermal stress that can crack or shatter the finished piece during or after firing.

How many slices come in a jar?
These are sold as a jar of assorted slices, and slice sizes and counts vary from pack to pack. The natural range of sizes lets you use larger slices as focal points and smaller ones as scattered detail.

How do I use murrini in a fused glass project?
Place individual slices on the surface of your base glass, such as a pendant, plate, dish, suncatcher, or ornament, then fire them in your kiln. The slices act as surface accents that fuse into the piece, not as a casting material or mold fill.

Working Notes

A full fuse schedule will melt these murrini flat and flush into the surface of your base glass, integrating the fish motif smoothly into the finished piece. A tack fuse schedule will preserve more of the raised relief of each slice, keeping the fish shape more distinct on the surface. The right approach depends on your design intent, your kiln, and the specific glass you are working with.

Always fire a small test piece first before committing to a full project. Kiln behavior varies, so match your schedule to your own equipment and glass rather than relying on a generic ramp rate. Keep every element in the project on the same COE to avoid thermal stress in the finished piece.
