Zinnia Casting Mold

The Zinnia Casting Mold from Creative Paradise casts a single zinnia flower shape in one firing, with the finished piece measuring 5.75 inches in diameter. The mold itself is 7.25 inches in diameter and 1.5 inches tall, giving the cavity enough depth to hold a substantial fill. The large cast flower works well as a standalone fused glass art piece, a suncatcher blank, or a decorative tile centerpiece.

Like all ceramic casting molds, this one is COE agnostic. Fill the cavity with frit, billets, or stacked sheet scrap and fire to a full fuse to bring out the zinnia petal detail. Creative Paradise lists a fill weight of 256 grams. The mold is reusable across many firings when properly primed and cared for between uses.

What does the Zinnia Casting Mold make?
It casts one zinnia flower shape, 5.75 inches in diameter, in a single firing. The finished piece suits wall art, suncatcher blanks, and decorative tile 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?
Creative Paradise lists 256 grams for this cavity. Weigh your glass and test a first run when the result matters, as fill weight can vary with glass type and how fully you load the cavity.

How do I prep the mold before casting?
Coat the cavity with a kiln shelf primer such as a boron nitride spray 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, 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.

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.
