The Holey Heart mold from Creative Paradise casts a single heart shaped piece with an opening through the center, finished at 2.5 inches long by 2 inches wide. The mold footprint is 3.75 inches by 3.5 inches, keeping it compact in the kiln. The built-in hole means the finished cast piece can be strung directly on cord or wire for pendants and ornaments, with no drilling needed after firing.
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 heart shape. Creative Paradise lists about 20 grams of glass per firing. As a kiln casting mold it is reusable across many firings when prepped and cared for properly.
What does the Holey Heart mold make?
It casts one heart shaped glass piece with a hole through the center, measuring 2.5 inches long by 2 inches wide. The opening lets you string the finished piece on cord or wire without drilling.
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 firing?
Creative Paradise lists about 20 grams. 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.
