Small Round Slump Ring Mold

The Small Round Slump Ring Mold from Creative Paradise is a ceramic ring form designed to produce glass dishes with a completely flat bottom. A sheet or fused glass blank is draped over the ring and fired on a slump schedule, so the glass softens around the form and settles into a level, stable dish shape. The mold measures 7.75 inches in diameter and 2 inches tall, with a center opening of 2.5 inches across.

To use it, set the mold on a primed kiln shelf or on kiln shelf paper, lay your glass over the ring, and run a slump schedule. Because this is a draping form rather than a frit casting mold, no cavity filling is involved. Like all ceramic kiln molds, it is COE agnostic and reusable across many firings when the surface is properly primed and maintained between runs.

What does the Small Round Slump Ring Mold make?
It produces a round glass dish with a flat, stable bottom. The glass drapes over the 7.75 inch ring during firing and settles into a dish shape, with the 2.5 inch center opening keeping the base level and even.

How do I use a slump ring mold?
Set the mold on a primed kiln shelf or on kiln shelf paper. Lay a glass sheet or fused blank over the ring, then fire a slump schedule. The glass softens during firing and drapes down over the ring, taking the round dish shape.

What COE glass can I use?
Any COE. Ceramic kiln 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 and adjust the anneal soak temperature to suit your COE.

How do I prep the mold before firing?
Prime the mold surface with a boron nitride spray or kiln wash and let it dry completely before placing glass over the form. Re-coat between firings as needed to prevent sticking.

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 mold 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 over the form.
• Set the mold on a primed kiln shelf or on kiln shelf paper before firing.
• Drape a glass sheet or fused blank over the ring. The glass will soften and settle into the dish shape during firing.
• The mold is COE agnostic. Use a slump schedule matched to your glass, adjusting the anneal soak temperature for your COE.
• 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 (double layer, COE96):

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