The Small Sushi Slumping Mold from Creative Paradise slumps a pre-made fusible glass piece into a sushi shape in a single firing. The mold measures 3.5 inches by 3.5 inches with a 4.75 inch diagonal and a slump depth of 0.5 inches. The compact footprint and the modest amount of glass required make it accessible for beginners and practical at any experience level.
To use the mold, place a compatible pre-fused or cut glass piece on the prepared form, set it in the kiln, and let the glass soften and drape into the shape by gravity. Like all ceramic slumping molds, this one is COE agnostic, so it works with COE96, COE90, or other compatible fusible glass. The mold is reusable across many firings when prepped and cared for properly.
What does the Small Sushi Slumping Mold make? It slumps a pre-made glass piece into a sushi shape, with a slump depth of 0.5 inches over a 3.5 inch square mold footprint. The finished piece works well as a small decorative dish, a jewelry component, or a standalone art glass accent.
How does slumping work with this mold? Place a compatible pre-fused or cut sheet glass piece on the prepared mold surface and fire to the slump temperature. The glass softens and settles into the form by gravity, taking on the mold's shape and depth.
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. 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 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 compatible pre-fused or cut sheet glass piece on the prepared mold surface. The glass softens and drapes into the form's 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 Rate Temp (F) Hold 1 300 1260 20 2 9999 950* 60
*Segment 2 is the anneal soak at 950 F for COE96. If using COE90, adjust this temperature to 900 F.
