Dome Slumping Mold

The Dome Slumping Mold from Creative Paradise is a large ceramic slumping form, 10.75 inches in diameter and 3.5 inches tall. A pre-cut glass blank or fused piece is placed over the dome and fired so the glass softens and settles by gravity, taking on the rounded curved profile of the form.

Like all ceramic slumping forms, this mold is COE agnostic and reusable across many firings when prepped properly. Coat the surface with a boron nitride spray or kiln wash before each use, and match your slumping schedule to the glass you are using.

What does the Dome Slumping Mold make?
It shapes a flat glass blank into a rounded dome. The finished piece takes on the curved profile of the form, with a base span of 10.75 inches and a rise of 3.5 inches.

What size glass blank do I need?
Cut your blank somewhat larger than 10.75 inches to allow for the glass to drape down over the sides of the dome. Test a first run to dial in the exact size for the drape depth you want.

What COE glass works with this mold?
Any COE. Ceramic slumping forms 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 and use this mold?
Coat the dome surface with a boron nitride mold primer such as ZYP or a kiln wash such as Hotline Primo Primer, and let it dry completely before placing your glass. Lay the prepared blank centered over the dome and fire to a slumping temperature suited to your glass and kiln.

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 dome 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 pre-cut glass blank centered over the dome. Cut the blank somewhat larger than 10.75 inches so it has room to drape down over the curve to the finished depth you want.
• 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 piece. Re-coat the mold with primer as needed between firings.
• The Slide Hi Temp brand separator is not recommended with these molds.
