Star Ornament Casting Mold

The Star Ornament Casting Mold from Creative Paradise casts two star shapes in a single firing: a long star measuring 5.75 inches by 3.75 inches and a five-pointed star measuring 4 inches by 3.5 inches. The mold footprint is 9 inches by 7 inches, so both ornament shapes fire together in one load.

Like all ceramic casting molds, this one is COE agnostic. Fill the cavities with frit, billets, or stacked sheet scrap and fire so the glass takes the shape of each star. Creative Paradise lists about 62 grams for the long star cavity and 68 grams for the five-pointed star cavity. The mold is reusable across many firings when prepped and cared for properly.

What does the Star Ornament Casting Mold make?
It casts two star shapes in one firing: a long star at 5.75 inches by 3.75 inches and a five-pointed star at 4 inches by 3.5 inches. They are well suited to ornaments, suncatchers, and decorative display pieces.

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 62 grams for the long star and 68 grams for the five-pointed star. Fill weight varies with how full you want 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 both 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, 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.
