Thin Tree Ornaments Casting Mold

The Thin Tree Ornaments mold from Creative Paradise casts two slender tree-shaped ornaments in a single firing. The tall cavity yields a finished piece measuring 7.25 inches long by 1.75 inches wide, and the short cavity yields one measuring 6.5 inches long by 1.5 inches wide. Both sit in a mold footprint of 9 inches by 5 inches, with a mold thickness of 1.75 inches.

Like all ceramic casting molds, this one is COE agnostic. Fill the cavities with frit, billets, or stacked sheet scrap and fuse each tree to shape. Creative Paradise lists about 64 grams of glass for the tall cavity and about 40 grams for the short one. The mold is reusable across many firings when prepped and cared for properly.

What does the Thin Tree Ornaments mold make?
It casts two tree-shaped pieces in one firing: a tall tree at 7.25 inches by 1.75 inches and a short tree at 6.5 inches by 1.5 inches. They are well suited to holiday ornaments, seasonal decor, and gift 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 cavity?
Creative Paradise lists about 64 grams for the tall tree and about 40 grams for the short tree. Weigh your glass and test a first run when the result matters, as fill weight can vary with how full you want each piece.

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, 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.
