Quad Holey Star Casting Mold

The Quad Holey Star casting mold from Creative Paradise casts four star shaped pieces with a hole through each one, all in a single firing. Each finished star measures 2.75 inches long by 2.25 inches wide, and the four cavities sit in a mold footprint of 6 inches by 5.5 inches by 1.25 inches thick. The hole in each star means finished pieces can be hung directly as ornaments, sun catchers, or pendants without any additional drilling.

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 star shape. Creative Paradise lists about 18 grams of glass per cavity. The mold is reusable across many firings when prepped and cared for properly.

What does the Quad Holey Star mold make?
It casts four star shaped pieces, each 2.75 inches by 2.25 inches, with a hole through each star, all in one firing. The hole lets finished pieces hang as ornaments, sun catchers, or pendants.

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 star?
Creative Paradise lists about 18 grams per cavity. Fill weight varies with how full you want each piece, 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 the 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.
