The Geometric Hoops Casting Mold from Creative Paradise casts three geometric hoop shapes in a single firing: a teardrop, a circle, and a square. The teardrop shape casts to 3 inches long by 2.5 inches wide, the circle comes out at 2.5 inches in diameter, and the square measures 2.75 inches by 2.75 inches. The mold body is 9 inches long by 3.75 inches wide by 1.5 inches tall.
Like all ceramic casting molds, this one is COE agnostic. Load each cavity with frit, billets, or stacked sheet scrap and fuse to the hoop shape. Creative Paradise lists fill weights of 19 grams for the teardrop, 18 grams for the circle, and 15 grams for the square. The mold is reusable across many firings when prepped and cared for properly.
What does the Geometric Hoops Casting Mold make?
It casts three geometric hoop shapes in one firing: a teardrop at 3 inches by 2.5 inches, a circle at 2.5 inches in diameter, and a square at 2.75 inches by 2.75 inches. The finished pieces work well as pendant blanks, earring components, and decorative cast elements.
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 19 grams for the teardrop, 18 grams for the circle, and 15 grams for the square. Weigh your glass and test a first run when the result matters, as fill weight can vary with how full you want each shape.
How do I prep the mold before casting?
Coat each 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 all three 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 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 pieces. Re coat the mold with primer as needed between firings.
- The Slide Hi Temp brand separator is not recommended with these molds.
