Scalloped Shelf Ring Slumping Mold

The Scalloped Shelf Ring slumping mold from Creative Paradise shapes a pre-made glass blank into a ring form with scalloped outer edges. The mold measures 12 inches in diameter and 2 inches tall, with a center opening of 6.5 inches. Place a prepared fused or pre-cut glass blank over the form, fire to the slump temperature, and gravity pulls the glass down around the scalloped profile to create a finished decorative ring piece.

Like all ceramic slumping molds, this one is COE agnostic. Any fusible glass blank placed over the form will soften and drape to the mold's contours when fired to the appropriate slumping temperature for your glass. The mold is reusable across many firings when primed and cared for properly.

What does the Scalloped Shelf Ring mold make?
It shapes a glass blank into a ring form with scalloped outer edges, following the mold's 12 inch outer diameter and 6.5 inch center opening. The result works well as a decorative shelf ring, centerpiece base, or dimensional display piece.

What COE glass can I use in 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.

What size glass blank do I need?
The mold is 12 inches in diameter with a 6.5 inch center opening. Use a glass blank sized to cover the mold's scalloped surface. Cut to fit or use a pre-fused blank, and test a first run to confirm sizing before committing to a finished piece.

How do I prep the mold before slumping?
Coat the mold 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 the 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 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 the glass so the glass does not stick.
• Place a pre-cut or pre-fused glass blank over the mold. The glass will soften and drape down over the scalloped form as it reaches slumping temperature.
• 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):

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