Holey Feather Casting Mold

The Holey Feather mold from Creative Paradise casts one open-work feather in a single firing, with the finished piece measuring 4.75 inches long. The mold footprint is 6.25 inches by 3 inches, fitting comfortably in most kilns alongside other work. The cavity captures the characteristic gaps between a feather's barbs, giving the cast glass piece a lacy, open quality that suits pendants, decorative panels, or wall accents.

Like all ceramic casting molds, this one is COE agnostic. Fill the cavity with frit, small billets, or stacked sheet scrap and fuse to the feather shape. Creative Paradise lists a fill weight of about 35 grams. As a kiln casting mold it is reusable across many firings when prepped and cared for properly.

What does the Holey Feather mold make?
It casts one open-work feather, 4.75 inches long, in a single firing. The open areas in the cavity reproduce the gaps between a feather's barbs in the finished cast glass piece.

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?
Creative Paradise lists about 35 grams per firing. Fill weight can vary with how full you want the cavity, so weigh your glass and test a first run when the result matters.

How do I prep the mold before casting?
Coat the 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 the 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 piece. 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.

*The 950 F hold marked with an asterisk is the anneal soak for COE96. If using COE90, adjust this temperature to 900 F.
