Butterfly Kiln Casting Mold

The Butterfly Kiln Casting Mold from Creative Paradise casts a single butterfly shape measuring 4 inches by 4 inches in one firing. The mold footprint is 5.5 inches by 5.5 inches, with a 7.75 inch diagonal, giving the cavity enough room to produce a detailed butterfly form suited to pendants, suncatcher panels, decorative accents, or mosaic centerpieces.

Like all ceramic casting molds, this one is COE agnostic. Load the cavity with frit, small billets, or stacked sheet scrap and fire to cast the butterfly shape. Creative Paradise lists a fill weight of about 121 grams for the cavity. The mold is reusable across many firings when prepped and cared for properly.

What does the Butterfly Kiln Casting Mold make?
It casts one butterfly shaped piece measuring 4 inches by 4 inches per firing. The finished piece works well as a pendant blank, suncatcher element, or decorative panel accent.

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?
Creative Paradise lists about 121 grams for the cavity. Fill weight can vary with how fully you pack the cavity, so weigh your glass and test a first run when the result matters.

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, 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 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.
