Three Kings Tray Slumping Mold

The Three Kings Tray Slumping Mold from Creative Paradise is part of the brand's one and done series, which combines fusing and slumping into a single kiln firing. It shapes a rectangular seasonal tray with a footprint of 13.25 inches by 7.25 inches and a depth of 1.5 inches. The diagonal measures 15.25 inches.

To use it, place a double-thick layer of sheet glass and frit directly on the primed mold surface, then fire the one and done schedule so the glass fuses and settles into the tray shape in one pass. Like all ceramic slumping molds it is COE agnostic, so it works with COE96, COE90, or other compatible fusible glass. Prime the mold before each firing with a boron nitride spray or kiln wash.

What does the Three Kings Tray mold make?
It shapes one rectangular tray measuring 13.25 inches by 7.25 inches with a 1.5 inch depth, suited to seasonal serving or display use.

What is the one and done method?
A double-thick layer of sheet glass with frit is placed on the mold and fired through a single schedule that reaches full fuse temperature, so the glass fuses and slumps into the tray form in one step without a separate fusing firing first.

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. Adjust the anneal soak temperature to match the glass you are using.

How do I prep the mold before firing?
Coat the mold surface with a boron nitride primer such as ZYP or a kiln wash such as Hotline Primo Primer, and let it dry completely before laying your glass on the form. 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 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 laying glass on the form so the glass does not stick.
• The one and done method uses a double-thick layer of sheet glass with frit placed directly on the primed mold surface. The single firing fuses the layers and slumps the glass into the tray shape in one pass.
• The mold is COE agnostic. Adjust the anneal soak in segment 5 for your COE: 950 F for COE96, or 900 F for COE90.
• Let the kiln cool fully before removing the finished tray. 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 (COE96, double-thick glass with frit):

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