Zany Zinnias Frit Casting Mold

The Zany Zinnias Frit Casting Mold from Creative Paradise casts two zinnia-shaped glass stakes in a single firing: a large stake at 8.5 inches and a small stake at 8 inches. The mold footprint is 10 inches by 5 inches by 1.5 inches thick, fitting both cavities side by side in one form.

Like all ceramic casting molds, this one is COE agnostic. Fill each cavity with frit, billets, or stacked sheet scrap and fuse the glass to the zinnia shape. Creative Paradise lists a fill of 78 grams for the large cavity and 75 grams for the small one. The mold is reusable across many firings when prepped and cared for properly.

What does the Zany Zinnias mold make?
It casts two zinnia-shaped glass stakes in one firing: a large piece at 8.5 inches and a small piece at 8 inches. Finished stakes are suited to garden art, window display, or decorative accents mounted on rods or copper pipe.

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 piece?
Creative Paradise lists 78 grams for the large cavity and 75 grams for the small one. 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 so the glass does not stick.

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, 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.
