Tree Frog Casting Mold

The Tree Frog Casting Mold from Creative Paradise casts a single large tree frog figure in one firing, with the finished piece measuring 8.5 inches long by 7 inches wide. The mold itself is 10.25 inches long by 9 inches wide and 1.75 inches tall, giving the cavity enough depth to capture the shape of the frog in cast glass.

Like all ceramic casting molds, this one is COE agnostic. Fill the cavity with frit, billets, or stacked sheet scrap and fuse so the glass takes the shape of the frog. Creative Paradise lists a fill weight of about 227 grams. As a kiln casting mold it is reusable across many firings when prepped and cared for properly.

What does the Tree Frog Casting Mold make?
It casts one tree frog figure per firing, with the finished piece measuring 8.5 inches long by 7 inches wide. It is well suited to decorative panels, nature-themed wall pieces, and sculptural glass 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?
Creative Paradise lists about 227 grams for this mold. Fill weight can vary depending on how full you want the cavity, so weigh your glass and test a first run when the result matters.

How do I prep the mold before casting?
Coat the cavity 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 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.
