Bullseye Glass Mold #7969, Large Origami Slumping Mold 8.06"

The Large Origami Slumping Mold from Bullseye Glass (design number 7969) is a slipcast ceramic slumping form that shapes a pre-cut glass sheet into a large faceted origami-style dish. The glass blank is placed over the form and heated in the kiln until it softens and settles into the origami fold pattern by gravity, then cooled. The mold is made by Creative Ceramics in Europe and imported by Bullseye, slipcast from a specially formulated clay body that accepts kiln wash uniformly and does not crack under repeated proper use.

The outer dimensions are 8.0625 inches by 1.625 inches (20 by 4 cm). These figures are provided for kiln fit planning. Because the molds are handmade and vary slightly in size, measure the actual mold before cutting your glass. It works with any COE fusible glass; match your slumping schedule to the glass you are using.

What does this mold make?
It slumps a pre-cut glass sheet into a large folded-look origami dish. The glass softens over the faceted form by gravity, picking up the origami fold pattern in the finished piece.

What glass works with this mold?
Any COE fusible glass. Ceramic slumping forms are COE agnostic, so the same mold works with COE96, COE90, or other compatible fusible glass. Match your firing schedule to the glass you are using.

How do I size my glass blank?
The outer mold dimensions are 8.0625 inches by 1.625 inches. Because these molds are handmade and vary slightly, measure your actual mold before cutting your glass sheet rather than relying on the listed dimensions alone.

How do I prepare the mold?
Coat the forming surface with kiln wash or a boron nitride shelf primer and allow it to dry completely before placing the glass. Re-coat as needed between firings.

Working Notes

These are guidelines, not guarantees. Every kiln fires a little differently, so test a small piece first 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 primer such as ZYP Boron Nitride Mold Primer, and allow it to dry completely before placing the glass.
• These molds are handmade and vary slightly in size. Measure your actual mold before cutting your glass sheet.
• Place the prepared glass sheet over the form. Use a slumping schedule suited to your glass and this mold's depth.
• Visually confirm the glass has fully settled into the form before ending the process hold. Let the kiln cool fully before removing the piece. Re-coat the mold with kiln wash as needed between firings.

Bullseye Suggested Slumping Schedule (starting point)

This is a suggested starting schedule, 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.

• Ramp at about 300 F per hour to the slump process temperature. Use the lowest temperature that fully forms the glass; Bullseye's published starting point for this mold is 1225 F.
• Hold about 30 minutes (Bullseye's published hold for this mold) to let the glass settle into the form.
• Drop as fast as possible (AFAP) to the anneal soak: about 900 F for COE90 glass, about 950 F for COE96 glass.
• Hold the anneal soak for about 1 hour.
• Cool at about 100 F per hour to 700 F, then drop as fast as possible to room temperature with the kiln door closed.
