Large Sea Turtle Casting Mold

The Large Sea Turtle Casting Mold from Creative Paradise casts a single sea turtle in one firing, with the finished casting measuring 10 inches by 9 inches. At that scale it produces a substantial art piece suited to wall display, decorative accents, or mixed-media work. The mold body measures 11.5 inches by 10.5 inches by 2 inches thick, so plan kiln shelf space accordingly before loading.

Creative Paradise lists a fill weight of 850 grams of glass per firing. Load the cavity with frit, billets, or stacked sheet scrap and fuse to the sea turtle shape. Like all ceramic casting molds it is COE agnostic, meaning the same mold works with COE96, COE90, or other fusible glass. It is reusable across many firings when prepped and cared for properly.

What does the Large Sea Turtle Casting Mold make?
It casts one sea turtle per firing, with a finished size of 10 inches by 9 inches. The scale makes it a practical choice for decorative wall pieces, large art glass panels, and prominent display accents.

How much glass does this mold need?
Creative Paradise lists about 850 grams per firing. At this scale, weigh your glass carefully and test a first run when the result matters, since fill depth affects the final surface and texture.

What COE glass can I use?
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 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 recommends using 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.
