Folded Square Slumping Mold

The Folded Square slumping mold from Creative Paradise shapes an 8 inch square glass blank into a folded square form in a single firing. The mold measures 8 inches by 8 inches with a diagonal of 12 inches, making it a practical size for beginners and experienced fusers who want to create a decorative square dish with softly draped sides.

To use the mold, place a pre-fused or pre-cut glass blank over the form, then fire to slumping temperature so the glass softens and settles into the folded shape by gravity. Like all ceramic slumping molds, this one is COE agnostic and reusable across many firings when prepped and cared for properly.

What does the Folded Square mold make?
It slumps an 8 inch square glass blank into a folded square dish form, with the sides settling into the mold's contours during firing.

What size glass blank do I need?
The mold is 8 inches by 8 inches. Use a pre-fused or pre-cut square blank sized to fit the mold. Test a first run to confirm fit and slump depth for your specific blank thickness.

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 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 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 glass blank.
• Place a pre-fused or pre-cut square glass blank over the mold so the glass can settle into the folded shape during firing.
• 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 2 is the anneal soak at 950 F for COE96. If using COE90, adjust this temperature to 900 F.
