Super Size Mini Circles Jewelry Casting Mold

The Super Size Mini Circles mold from Creative Paradise casts twelve small round discs in a single firing, with each finished disc measuring 0.5 inches in diameter. The twelve cavities sit within a compact mold footprint of 3.5 inches by 3 inches, at a depth of 1.25 inches, making it an efficient way to produce a full batch of miniature pendant blanks, earring fronts, confetti accents, or mosaic dots at once.

Like all ceramic casting molds, this one is COE agnostic. Fill the cavities with frit, powder, or small scrap and fuse to the rounded disc shape. The manufacturer lists roughly 1 gram of glass per cavity. As a kiln casting mold it is reusable across many firings when prepped and cared for properly.

What does the Super Size Mini Circles mold make?
It casts twelve flat backed discs, each 0.5 inches in diameter, in one firing. They are well suited to jewelry blanks, confetti accents, small cabochons, and mosaic or mixed media 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 disc?
Creative Paradise lists about 1 gram per cavity. Fill weight varies with how full you want each disc, so 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 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 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, powder, 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.
