Small Butterflies Casting Mold

The Small Butterflies casting mold from Creative Paradise casts two butterfly shapes in a single firing, one larger and one smaller, within a mold footprint of 5.25 inches by 4.25 inches. The two cavities produce butterfly forms at different scales, making them practical for pendant blanks, decorative pins, ornament accents, or mosaic work.

Like all ceramic casting molds, this one is COE agnostic. Fill the cavities with frit, small billets, or stacked sheet scrap and fuse to the butterfly shape. Creative Paradise lists fill weights of about 38 grams for the larger cavity and about 32 grams for the smaller one. As a kiln casting mold it is reusable across many firings when prepped and cared for properly.

What does the Small Butterflies mold make?
It casts two butterfly shaped pieces in one firing: one larger form and one smaller form. They suit jewelry blanks, decorative accents, and small mosaic or ornament 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 cavity?
Creative Paradise lists about 38 grams for the larger butterfly and about 32 grams for the smaller one. Weigh your glass and test a first run when the result matters, as fill weight can vary with how full you load each cavity.

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 both 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 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.
