Dome Mushroom Cap Slumping Mold

The Dome Mushroom Cap slumping mold from Creative Paradise shapes a glass blank over a rounded dome form, producing a single finished piece that measures 6.25 inches in diameter and stands 2.25 inches tall at its peak. The broad, organic dome profile suits decorative bowl forms, sculptural accent pieces, and layered art glass work.

To use it, place a pre-fused blank or a double layer of sheet glass over the primed dome, then fire a drape schedule suited to your glass and kiln. As the kiln heats, the glass softens and settles over the form by gravity, taking the dome cap shape. Like all ceramic slumping molds, this one is COE agnostic and reusable across many firings when prepped and cared for properly.

What does the Dome Mushroom Cap mold make?
It drapes one piece of glass into a dome cap shape, 6.25 inches in diameter and 2.25 inches tall, in a single firing.

How do I use a draping mold like this one?
Place a pre-fused blank or a double layer of sheet glass on top of the primed dome form. As the kiln heats, the glass softens and sags over the form by gravity. Follow a drape schedule, not a full fuse schedule, and let the kiln cool completely before removing the piece.

What COE glass can I use with this mold?
Any COE. Ceramic slumping molds are COE agnostic, so this mold works with COE96, COE90, or other fusible glass. Match your firing schedule to the glass you are using.

How do I prep the mold before draping?
Coat the dome 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 glass on the form so the glass does not stick.

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 drape schedule suited to your glass and kiln.

• Prime the dome 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 glass on the form so the glass does not stick.
• Drape a pre-fused blank or a double layer of sheet glass over the dome. The manufacturer's suggested schedule is based on a double layer of COE96 glass.
• The mold is COE agnostic. Use a drape schedule matched to your glass, adjusting the final anneal soak for your COE.
• Let the kiln cool fully before removing the draped 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.

Drape (COE96): suggested for a double layer of COE96 glass.

*Segment 3 is the anneal soak at 950 F for COE96. If using COE90, adjust this temperature to 900 F.
