Bullseye Glass Mold #7968, Small Origami Slumping Mold 6.37"

The Small Origami Slumping Mold from Bullseye Glass forms a compact dish with angular, folded facets that give the finished piece the look of paper origami. A pre-cut or pre-fused glass sheet is placed onto the form and fired in the kiln, where the glass softens and settles into the faceted shape by gravity. The finished dish is a practical size for holding rings, earrings, or other small items.

The mold is slipcast from a specially formulated clay body by Creative Ceramics in Europe and imported by Bullseye Glass. The surface is exceptionally smooth and accepts kiln wash uniformly, and the material does not crack under repeated proper use. The outer dimensions are 6.375 inches by 1.313 inches (16 by 3 cm). Because these molds are handmade and vary slightly from piece to piece, measure your mold before cutting glass.

What does the Small Origami Slumping Mold make?
It slumps a flat glass sheet into a small dish with angled, folded facets that suggest the look of origami paper.

What size glass blank do I need?
The outer mold dimensions are 6.375 inches by 1.313 inches (16 by 3 cm), but individual molds vary slightly because they are handmade. Measure your mold before cutting glass so the blank fits correctly.

What COE glass can I use?
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 prepare the mold before slumping?
Coat the forming surface with kiln wash or shelf primer and let it dry completely before placing glass on the mold. These molds accept kiln wash uniformly.

Working Notes

These are guidelines, not guarantees. Every kiln fires a little differently, so test a small piece first, visually confirm the slump is complete, and follow Bullseye's published Suggested Slumping Schedule for your glass and mold depth.

• Coat the forming surface with kiln wash or a boron nitride mold primer such as ZYP Boron Nitride Mold Primer, and let it dry completely before placing glass on the mold.
• Use a pre-cut or pre-fused glass sheet sized to the mold. Because individual molds are handmade and vary slightly, measure your mold before cutting.
• This is a shallow form at 1.313 inches deep. For shallow slumps, start at the lower end of the slump temperature range and check the piece visually during firing.
• The mold is COE agnostic. Match your firing schedule to your glass and adjust the anneal soak temperature for your COE.
• Let the kiln cool fully before removing the slumped piece. Re coat the mold with kiln wash as needed between firings.

Bullseye Suggested Slumping Schedule (starting point only):

This is a suggested starting schedule based on Bullseye's published guidance for this depth of form, not a guarantee. Every kiln fires differently. Follow Bullseye's published Suggested Slumping Schedule for your glass and mold depth, visually confirm the slump, and test a small piece first.

Slump temp note: use the lowest temperature that fully forms the glass. For a shallow form like this one, a slightly cooler temperature may be sufficient. Visually confirm the slump is complete before moving on.
*Anneal soak: about 900 F for COE90 (standard Bullseye glass). For COE96, adjust to about 950 F.
