Round Harvest Platter Slumping Mold

The Round Harvest Platter slumping mold from Creative Paradise shapes a single round serving platter with an inner diameter of 12 inches and a depth of 1 inch. The overall mold measures 13 inches in diameter and 1.75 inches tall, giving the finished piece a shallow, wide bowl profile suited to seasonal displays and serving.

Creative Paradise designed this mold for a One-and-Done approach: load two layers of sheet glass with frit decoration directly onto the prepared form and fire a combined fuse-and-slump in a single kiln run. Like all ceramic slumping molds, it is COE agnostic and reusable across many firings when prepped and cared for properly.

What does the Round Harvest Platter mold make?
It shapes a single round serving platter with a 12 inch inner diameter and 1 inch of depth, finished as a shallow bowl form suited to a seasonal table setting or display.

What is the One-and-Done method for this mold?
Instead of pre-fusing a blank and slumping in a second firing, the One-and-Done approach lets you load two layers of sheet glass with frit directly onto the prepared mold and complete both the fuse and the slump in one firing. Creative Paradise provides a six-segment schedule for COE96 glass using this method.

What COE glass can I use?
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 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 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 glass so the glass does not stick.
• For the One-and-Done method, lay two layers of sheet glass over the prepared mold and add frit decoration. The Creative Paradise schedule is designed for this double layer with frit on COE96 glass.
• The mold is COE agnostic. Adjust the final anneal soak for your COE: 950 F for COE96, 900 F for COE90.
• Let the kiln cool fully before removing the finished platter. 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.

One-and-Done Slump (COE96): for slumping a double layer of COE96 glass with frit.

*Segment 5 is the anneal soak at 950 F for COE96. If using COE90, adjust this temperature to 900 F.
