Feather Trio Kiln Casting Mold

The Feather Trio kiln casting mold from Creative Paradise casts three feather shaped glass pieces in a single firing: one pendant at 3.5 inches long and a matched pair of earring pieces, each 2.5 inches long. The mold footprint is 5 inches by 4.5 inches, keeping the three cavities in a manageable layout for studio work.

Like all ceramic casting molds, this one is COE agnostic. Fill the cavities with frit, small billets, or stacked sheet scrap and fuse to the feather shape. The manufacturer lists 15 grams of glass for the pendant cavity and 8 grams each for the two earring cavities. As a kiln casting mold it is reusable across many firings when prepped and cared for properly.

What does the Feather Trio mold make?
It casts three feather shaped pieces in one firing: one pendant at 3.5 inches long and two earring pieces each at 2.5 inches long. They are well suited to jewelry sets, wearable art, and nature themed glass work.

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 piece?
Creative Paradise lists about 15 grams for the pendant cavity and about 8 grams for each earring cavity. Fill weight can vary with how full you load each cavity, so weigh your glass and test a first run when the result matters.

How do I prep the mold before casting?
Coat the cavities 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 all three cavities 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.
