Fluted Bowl Slumping Mold

The Fluted Bowl Slumping Mold from Creative Paradise takes a round fused blank and slumps it over a fluted form, shaping it into a ridged bowl in a single firing. The mold measures 10.75 inches by 10.75 inches, with a diagonal of 15 inches. Place your pre-made blank on the prepared mold and the glass softens and settles into the fluted shape as the kiln heats.

Like all ceramic slumping molds, this one is COE agnostic. Any compatible fusible glass blank will slump to the fluted form when fired on an appropriate schedule. Creative Paradise suggests using a double layer of glass for this mold. The mold is reusable across many firings when prepped and cared for properly.

What does the Fluted Bowl Slumping Mold make?
It slumps a round fused blank into a fluted bowl with a ridged profile. The finished bowl takes the shape of the mold's fluted form.

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.

How thick should my blank be?
Creative Paradise suggests a double layer of glass for this mold. Test a first run when the result matters, as results vary by kiln and glass.

How do I prep the mold before slumping?
Coat the mold surface with a kiln shelf primer such as a boron nitride spray or a kiln wash such as Hotline Primo Primer, and let it dry completely before placing your blank so the glass does not stick.

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 blank so the glass does not stick.
• Place your pre-made round fused blank on top of the prepared mold. Creative Paradise suggests a double layer of glass for this form.
• The mold is COE agnostic. Use a slump schedule matched to your glass, adjusting the 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):

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