This pack of COE90 murrini brings together a Halloween themed assortment of slices. Black spiders appear on bright orange and on lime green backgrounds, black bats sit against orange, and white and gray skulls surface on black backgrounds. Another motif shows a striped figure in green and white on a black background, reminiscent of a classic Halloween monster. Solid black accent pieces round out the mix, and the overall palette of orange, lime green, black, and white gives the collection a strongly seasonal character.
Murrini, also called millefiori, are small cross-section slices of patterned glass cane, so each motif repeats reliably from slice to slice. To use them, arrange individual slices on the surface of a prepared COE90 glass base, such as a jewelry pendant, suncatcher, small dish, plate, or ornament, and fire the piece so the murrini fuse into the surface as decorative accents.
What Halloween motifs are included in this mix?
The assortment includes black spiders on orange and lime green backgrounds, black bats on orange backgrounds, white and gray skulls on black backgrounds, and a striped monster figure in green and white on black. Solid black accent pieces are mixed in as well. Colors throughout are orange, lime green, black, and white.
What COE glass do I need to use with these murrini?
These are COE90 murrini, made to a 90 coefficient of expansion. Use them only with glass of the same COE. Combining glass of mismatched coefficients creates thermal stress during firing and cooling, which can cause cracking.
How many slices come in a pack?
This mix is sold as a jar of assorted slices; slice sizes, counts, and the exact motif balance vary from pack to pack. Each jar contains a spread of the Halloween motifs in a range of sizes.
How do I incorporate murrini into a fused glass project?
Place individual slices on the surface of your COE90 glass base and arrange them as accents before firing. A full fuse will melt the slices flat and flush with the surrounding glass, while a tack fuse will keep them raised with a more pronounced three-dimensional profile. Either approach keeps the Halloween motifs clearly visible in the finished piece.

Working Notes
A full fuse reaches a temperature that allows the murrini to melt down flat and integrate smoothly into the surface of your glass. This gives the finished piece a flush, even texture with the Halloween motifs embedded within the surface layer. A tack fuse, fired to a lower peak temperature, leaves the slices raised above the base glass, preserving their rounded, three-dimensional character and adding tactile interest to small decorative pieces, pendants, or ornaments.
Because every kiln fires differently and glass response varies by color and thickness, always test a small sample piece before committing to a full project firing. Adjust your ramp schedule and hold times based on your specific glass and kiln behavior. Your own test results are the most reliable guide.
