Each slice in this jar shows a black butterfly silhouette on a white and clear ground, ringed with a light gray border. Small red-orange accents sit within the wings, adding a touch of warmth against the deep black body. The motif reads clearly even at the smaller end of the size range.
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 accents on pendants, jewelry, plates, dishes, suncatchers, and ornaments. These are COE90 murrini; use them only with glass of the same COE.
What does the pattern on these murrini look like? A black butterfly silhouette with small red-orange accents in the wings, set against a white ground and outlined with a light gray border.
What glass do I use with these murrini? These are COE90 murrini. Use them only with glass of the same COE. Mixing glass of different coefficients of expansion introduces stress that can crack the finished piece.
How are these sold? Sold by the jar as an assortment of slices. Slice sizes and counts vary from jar to jar.
How do I use these in a fused glass project? Place individual slices face-up on the surface of your prepared glass and fire. A full fuse melts them flat and flush for a smooth, integrated look; a tack fuse preserves more of their raised profile.
Specifications
SKU: 172258 COE: COE90 Form: jar of assorted slices Pattern: black butterfly with red-orange wing accents on a white ground Working Notes
A full fuse melts these slices flat, integrating them smoothly into the surface. A tack fuse stops before full melt and keeps more of the raised, dimensional character. The right choice depends on your glass, your kiln, and the look you want. Fire a small test piece first and use a firing schedule suited to your COE90 glass.
