Leaves and Acorn Casting Mold

The Leaves and Acorn mold from Creative Paradise casts four nature-themed pieces in a single firing: an acorn, a maple leaf, an oak leaf, and a pin oak leaf. Finished piece sizes range from 1.25 inches to 4.5 inches in length, and the mold footprint is 10 inches by 8 inches, making it a productive way to cast a set of botanical decorative pieces in one session.

Like all ceramic casting molds, this one is COE agnostic. Load each cavity with frit, small billets, or stacked sheet scrap and fuse to the leaf or acorn shape. Fill weights vary by cavity: the acorn takes about 7 grams, the pin oak leaf about 25 grams, the maple leaf about 28 grams, and the oak leaf about 33 grams. The mold is reusable across many firings when prepped and cared for properly.

What does the Leaves and Acorn mold make?
It casts four botanical pieces in one firing: an acorn, a maple leaf, an oak leaf, and a pin oak leaf. Finished pieces range from 1.25 inches to 4.5 inches in length, suited to pendants, ornaments, and decorative accents.

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 7 grams for the acorn, 25 grams for the pin oak leaf, 28 grams for the maple leaf, and 33 grams for the oak 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 each 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, 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.
