Columbine Flowers Casting Mold

The Columbine Flowers Casting Mold from Creative Paradise casts four botanical pieces in a single firing: a large flower, a small flower, a large leaf, and a small leaf. The large flower measures 2.75 inches in diameter, the small flower 2 inches in diameter, the large leaf 2.25 inches by 2.25 inches, and the small leaf 2 inches by 1.75 inches. The mold footprint is 8.25 inches long by 7.5 inches wide by 1.5 inches thick, so all four cavities fit within a single kiln shelf placement.

Like all ceramic casting molds, this one is COE agnostic. Fill each cavity with frit, small billets, or stacked sheet scrap and fuse to shape. Creative Paradise lists fill weights of about 34 grams for the large flower, 20 grams for the small flower, 18 grams for the large leaf, and 14 grams for the small leaf. The mold is reusable across many firings when prepped and cared for properly.

What does the Columbine Flowers mold cast?
It casts four pieces per firing: a large flower (2.75 inch diameter), a small flower (2 inch diameter), a large leaf (2.25 by 2.25 inches), and a small leaf (2 by 1.75 inches).

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 cavity?
Creative Paradise lists about 34 grams for the large flower, 20 grams for the small flower, 18 grams for the large leaf, and 14 grams for the small leaf. 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 all four 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.
