Flouncy Shelf Ring Slumping Mold

The Flouncy Shelf Ring Slumping Mold from Creative Paradise is a ceramic shelf ring for draping a pre-fused glass blank into a rimmed bowl with a flouncy, undulating edge. The form measures 13 inches in diameter and 2 inches tall, with a 3 inch center opening that lets the softened glass settle into the bowl shape during the slump firing.

To use it, prime the ring surface with boron nitride spray or kiln wash, set a pre-fused glass blank over the form, and fire to a slump temperature. The mold is COE agnostic and reusable across many firings when cared for properly.

What does the Flouncy Shelf Ring mold make?
It produces a slumped rimmed bowl with a flouncy, ruffled edge. A pre-fused glass blank draped over the 13 inch ring softens in the kiln and takes the undulating rim profile of the form.

How do I use a shelf ring slumping mold?
Prime the ring with boron nitride or kiln wash and let it dry. Place a pre-fused glass blank over the form and fire to a slump schedule. The glass softens by gravity and conforms to the shelf ring, picking up the flouncy rim shape.

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

Does the slump temperature change when using a foot?
Yes. Creative Paradise notes that if you are slumping onto a foot, raise the peak slump temperature in segment 2 from 1280 F to 1290 F.

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 slump schedule suited to your glass and kiln.

• Prime the ring surface with a boron nitride mold primer such as ZYP Boron Nitride Mold Primer, or a kiln wash such as Hotline Primo Primer, and let it dry completely before placing glass.
• Use a pre-fused glass blank sized to drape over the 13 inch ring. The blank softens and takes the flouncy rim profile as it heats.
• If slumping onto a foot, raise the peak slump temperature in segment 2 from 1280 F to 1290 F.
• The mold is COE agnostic. Use a slump schedule matched to your glass, and adjust the anneal soak temperature for your COE: 950 F for COE96, 900 F for COE90.
• Let the kiln cool fully before removing the slumped 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.

Slump (COE96): suggested for two layers of pre-fused glass.

*If slumping onto a foot, adjust segment 2 to 1290 F. For COE90, adjust the segment 3 anneal soak to 900 F.
