Small Hi-Low Bowl Slumping Mold

The Small Hi-Low Bowl Slumping Mold from Creative Paradise is a ceramic slumping form that drapes a pre-made glass sheet or fused blank into a small hi-low bowl. The outer mold measures 7 inches in diameter and 3 inches tall. The inner bowl form is 5.5 inches in diameter and 2 inches deep, giving the finished piece its characteristic hi-low stepped profile.

Slumping works by placing a pre-cut or pre-fused glass sheet over the prepared form, then heating the kiln until the glass softens and settles into the mold shape by gravity. The mold is ceramic and COE agnostic, so it works with COE96, COE90, or other fusible glass. Creative Paradise provides a suggested slump schedule for a double layer of COE96 glass. As a ceramic slumping mold it is reusable across many firings when prepped and cared for properly.

What does the Small Hi-Low Bowl Slumping Mold make?
It slumps a glass sheet or pre-fused blank into a small hi-low bowl. The inner form is 5.5 inches in diameter and 2 inches deep, producing a finished bowl with a stepped hi-low profile.

How does slumping work with this form?
A pre-cut glass sheet or pre-fused blank is placed over the prepared mold surface, then the kiln is heated until the glass softens and drapes into the bowl shape by gravity. The kiln is then cooled through an anneal soak to relieve stress in the finished piece.

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 and anneal soak 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 glass on the form. 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 glass so the glass does not stick.
• Place a pre-cut glass sheet or pre-fused blank over the mold form. Creative Paradise suggests a double layer of glass for this bowl shape.
• 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 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 9 is the anneal soak at 950 F for COE96. If using COE90, adjust this temperature to 900 F.
