Large Heart Slumping Mold

The Large Heart Slumping Mold from Creative Paradise forms a heart shaped dish from a pre-made glass blank or fused piece. The mold measures 8.25 inches long by 7.5 inches wide, with a depth of 1.5 inches that gives the finished dish its shallow bowl profile. Place a cut or fused glass blank over the form and fire to let the glass soften and settle into the heart shape.

Like all ceramic slumping molds, this one is COE agnostic. It works with COE96, COE90, or other fusible glass. Match your slump firing schedule and anneal soak to the glass you are using. The mold is reusable across many firings when prepped and cared for properly.

What does the Large Heart Slumping Mold make?
It forms one heart shaped dish per firing. The mold is 8.25 inches long by 7.5 inches wide with a 1.5 inch depth, giving the finished piece a shallow bowl profile.

What size glass blank do I need?
Cut or prepare a blank large enough to cover the heart outline with some overhang. A test run will confirm how much material you need for your glass thickness and firing schedule.

What COE glass can I use?
Any COE. Ceramic slumping molds are COE agnostic, so the same mold works with COE96, COE90, or other fusible glass. Adjust the anneal soak temperature to match your glass.

How do I prep the mold before slumping?
Coat the mold surface 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 placing the glass. Re coat between firings as needed.

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 slumping schedule suited to your glass and kiln.

• Prime the mold surface with a boron nitride mold primer such as ZYP Boron Nitride Mold Primer, or a kiln wash, and let it dry completely before placing the glass so the glass does not stick.
• Place a pre-cut or pre-fused glass blank over the mold, centered on the heart form. The glass will soften and drape into the heart shape as the kiln heats.
• The mold is COE agnostic. Use a slump schedule matched to your glass and adjust the final anneal soak temperature for your COE.
• Let the kiln cool fully before removing the dish. 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.

Slump (COE96):

*Segment 2 is the anneal soak at 950 F for COE96. If using COE90, adjust this temperature to 900 F.
