Large Fluted Shelf Ring Slumping Mold

The Large Fluted Shelf Ring from Creative Paradise is a ceramic slumping mold that shapes a pre-fused glass blank into a fluted dish with a flat bottom. The mold measures 11.25 inches in diameter and 3 inches tall, with a center opening of 3.75 inches in diameter. A pre-fused glass blank is placed over the ring form and fired so the glass softens and drapes into the fluted shape, producing a finished dish with defined fluted sides and a flat base.

Like all ceramic slumping molds, this form is COE agnostic. It works with COE96, COE90, or other fusible glass, provided you match the firing schedule to the glass you are using. Creative Paradise suggests using two layers of pre-fused glass with the provided slump schedule. The mold is reusable across many firings when prepped and cared for properly.

What does the Large Fluted Shelf Ring mold make?

How do I prepare the mold before slumping?
Coat the mold surface with a kiln shelf primer such as a boron nitride spray or a kiln wash such as Hotline Primo Primer, and let it dry completely before placing your glass blank on the form.

What size glass blank do I need?
The mold is 11.25 inches in diameter. Use a blank sized to span the full ring form. Creative Paradise suggests two layers of pre-fused glass for the provided slump schedule.

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 your glass.
• Place a pre-fused glass blank over the ring form. Creative Paradise suggests two layers of pre-fused glass for the provided slump schedule.
• The mold is COE agnostic. Use a slump schedule matched to your glass, adjusting the final anneal soak for your COE.
• Let the kiln cool fully before removing the slumped 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.

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

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