S Curve Slumping Mold

The S Curve Slumping Mold from Creative Paradise shapes a pre-made glass blank into a flowing S curve form in a single firing. The mold measures 10 inches long by 6 inches wide, with a diagonal of 11.75 inches, giving enough surface area to slump a standard fused blank or cut sheet into the curved profile.

To use it, a fired or cut glass blank is placed over the mold surface and the kiln is brought up to a slumping temperature. As the glass softens, gravity draws it down to follow the S curve contour of the mold. Like all ceramic slumping molds, this one is COE agnostic and reusable across many firings when prepped and cared for properly.

What does the S Curve Slumping Mold make?
It shapes a glass blank into an S curve form. The finished piece follows the mold contour and works well as a decorative plate, functional dish, or sculptural panel.

What size glass blank do I need?
The mold is 10 inches long by 6 inches wide, with a diagonal of 11.75 inches. Cut or fuse a blank sized to cover the area you want to slump, then test a first run to confirm fit before committing to a finished piece.

What COE glass can I use in this mold?
Any COE. Ceramic slumping molds are COE agnostic, so the same mold works with COE96, COE90, or other fusible glass. Match your slumping 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 or a kiln wash such as Hotline Primo Primer, and let it dry completely before placing your blank so the glass does not stick to the mold.

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 a pre-fused or cut glass blank over the mold, centered on the form, and fire to a slumping schedule matched to your glass.
• The mold is COE agnostic. Match your slumping schedule to your glass and adjust 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.
