Medium Hi-Low Bowl Slumping Mold

The Medium Hi-Low Bowl Slumping Mold from Creative Paradise shapes a pre-fused glass blank or a double layer of sheet glass into a hi-low bowl form in a single kiln firing. The finished interior measures 7 inches in diameter and 2.75 inches deep, with the mold itself measuring 9 inches in diameter and 4 inches tall.

Like all ceramic slumping molds, this one is COE agnostic. A prepared glass blank is placed over the form and fired on a slumping schedule, softening and settling into the hi-low contour by gravity. The mold is reusable across many firings when prepped and cared for properly.

What does the Medium Hi-Low Bowl mold make?
It slumps a glass blank into a hi-low bowl with an interior of 7 inches in diameter and 2.75 inches deep. The varied floor contour gives the finished piece depth variation across its base.

What COE glass can I use with 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 glass do I place on the mold?
Creative Paradise suggests a double layer of sheet glass. You can also use a pre-fused blank cut to fit the interior. Either way, the glass softens and drapes into the hi-low shape during the slump firing.

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 your glass.

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 so the glass does not stick.
• Place a double layer of sheet glass or a pre-fused blank on the mold. The glass softens and drapes into the hi-low contour during firing.
• The mold is COE agnostic. Use a slumping schedule matched to your glass, adjusting the final anneal soak for your COE.
• Let the kiln cool fully before removing the slumped bowl. 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, double layer of glass):

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