Holey Heart Choker Kiln Casting Mold

The Holey Heart Choker mold from Creative Paradise casts one heart shaped pendant with a hole built into the cast shape, finished at 2.75 inches long. The hole forms during the firing so a choker cord or thin chain can pass directly through the piece, making it wearable without a separate bail or jump ring.

Like all ceramic casting molds, this one is COE agnostic. Fill the cavity with frit, small billets, or stacked sheet scrap and fuse so the glass takes the heart shape with its integral opening. Creative Paradise lists a fill weight of about 34 grams. The mold is reusable across many firings when prepped and cared for properly.

What does the Holey Heart Choker mold make?
It casts one heart shaped pendant, 2.75 inches long, with a hole cast into the design. The hole allows cord or chain to pass through so the finished piece can be worn directly as a choker pendant.

What is the hole in the heart for?
The hole is part of the mold cavity, so it forms during casting rather than being drilled afterward. It is designed to accept a choker cord or thin chain, so the pendant is ready to string once it comes out of the kiln.

How much glass do I need for this mold?
Creative Paradise lists about 34 grams. Weigh your glass and run a test firing when the result matters, since fill weight can vary slightly with how you pack the cavity.

What COE glass can I use and how do I prep the mold?
Any COE works, since ceramic casting molds are COE agnostic. Prime the cavity with a boron nitride spray (such as ZYP) or a kiln wash such as Hotline Primo Primer and let it dry completely before adding glass.

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 recommends using 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.

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