Radiant Mushroom Hump Slumping Mold

The Radiant Mushroom Hump Slumping Mold from Creative Paradise is a ceramic hump form that shapes a pre-made glass sheet into a rounded mushroom cap profile. A pre-cut or pre-fused glass sheet is placed over the primed form and heated so the glass softens and drapes around the hump by gravity. The finished piece measures 5.5 inches in diameter, and the mold stands 2.25 inches tall.

Like all ceramic slumping forms, this mold is COE agnostic. It works with COE96, COE90, or other compatible fusible glass, and the same mold can be used across many firings when properly primed and cared for.

What does the Radiant Mushroom Hump Slumping Mold make?
It shapes a pre-made glass sheet into a rounded, domed mushroom cap form, approximately 5.5 inches in diameter, by draping the glass over the hump during firing.

How do I use a hump mold?
Prime the mold surface, center a pre-cut or pre-fused glass sheet over the top of the hump, and fire to a drape schedule. The glass softens and settles around the form by gravity, taking on the mushroom cap shape.

What COE glass can I use with this mold?
Any COE. Ceramic slumping 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 do I prep the mold before use?
Coat the mold surface with a boron nitride mold primer such as ZYP or a kiln wash such as Hotline Primo Primer, and let it dry completely before placing your 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 drape 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 your glass so the glass does not stick.
• Place a pre-cut or pre-fused glass sheet centered over the top of the hump, sized to drape over the 5.5 inch form.
• 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 shaped piece. Re-coat the mold with primer as needed between firings.

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):

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