Large Feather Trio Casting Mold

The Large Feather Trio mold from Creative Paradise casts three feathers of graduated sizes in a single firing. The large feather measures 8 inches long, the medium 6 inches long, and the small 5.5 inches long, giving you a complete set of feather shapes from one load. The overall mold footprint is 9.5 inches by 7.5 inches.

Fill each cavity with frit, small billets, or stacked sheet scrap and fuse to the feather shape. Creative Paradise lists about 70 grams for the large cavity, 50 grams for the medium, and 45 grams for the small. Like all ceramic casting molds, this one is COE agnostic and reusable across many firings with proper prep and care.

What does the Large Feather Trio mold make?
It casts three feathers in one firing: a large at 8 inches long, a medium at 6 inches long, and a small at 5.5 inches long. The graduated sizes work well as display pieces, nature-themed accents, or components in larger fused glass compositions.

What COE glass can I use in this mold?
Any COE. Ceramic casting molds are COE agnostic, so the same mold works with COE96, COE90, or other fusible glass. Match your firing schedule to the glass you are using.

How much glass do I need per cavity?
Creative Paradise lists about 70 grams for the large feather, 50 grams for the medium, and 45 grams for the small. Weigh your glass and test a first run when the result matters.

How do I prep the mold before casting?
Coat each cavity with a kiln shelf primer such as a boron nitride spray (for example ZYP) or a kiln wash such as Hotline Primo Primer, and let it dry completely before adding glass. Re-coat as needed between firings.

Working Notes

These are guidelines, not guarantees. Every kiln fires a little differently, so test a small run first when the result matters and follow a casting schedule suited to your glass and kiln.

• Prime each cavity with a boron nitride mold primer such as ZYP Boron Nitride Mold Primer, or a kiln wash, and let it dry completely before adding glass so the glass does not stick.
• Fill with frit, small billets, or stacked sheet scrap. For a tack fired surface, the manufacturer suggests powder and fine frit filled uniformly to about a quarter inch.
• The mold is COE agnostic. Use a full fuse schedule matched to your glass, adjusting the final anneal soak for your COE.
• Let the kiln cool fully before removing the cast pieces. Re-coat the mold with primer as needed between firings.
• The Slide Hi Temp brand separator is not recommended with these molds.

Creative Paradise Suggested Firing Schedule

This is a suggested COE96 starting schedule, not a guarantee. Every kiln fires differently. Test a small run and adjust the schedule for your glass and kiln.

Full Fuse (COE96):

Tack Fire (COE96): for a tack fired surface, fill uniformly to about a quarter inch with powder and fine frit.

*Segment 4 is the anneal soak at 950 F for COE96. If using COE90, adjust this temperature to 900 F.
