The Starfish Casting Mold from Colour de Verre is a reusable ceramic frit-casting mold that casts sea creature accent pieces and paperweights in a single firing. The mold casts a single detailed starfish with textured arms, a coastal accent piece for shelf displays, tabletops, or home accents.
The finished starfish measures about 4 inches (10 cm) across, and the mold takes about 110 grams of glass per firing. Like all ceramic casting molds, this one is COE agnostic, so the same mold works with COE96, COE90, or other compatible fusible glass. Prime the cavities before every use and follow a fuse schedule matched to your glass.
What does the Starfish Casting Mold make?
It casts one detailed starfish per firing, about 4 inches (10 cm) across. The finished pieces work well as paperweights, shelf accents, and coastal home decor.
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?
Colour de Verre lists about 110 grams of frit for this mold. 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 mold primer before every firing, such as ZYP BN Lubricoat or 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 cavities with ZYP Boron Nitride Mold Primer or Hotline Primo Primer before every use, and let the primer dry completely before adding glass so the cast pieces release cleanly.
- Fill the cavities with frit. Colour de Verre lists about 110 grams for this mold. Weigh your glass and adjust as needed based on your test results.
- The mold is COE agnostic. Use a full fuse schedule matched to your glass.
- Let the kiln cool fully before removing the cast pieces. Re-coat the mold with primer before the next firing.
