Neck Only Bottle Slumping Mold

The Neck Only Bottle Slumping Mold from Creative Paradise shapes the neck portion of a flat bottle form in a single slump firing. When paired with any of the Creative Paradise textured fusing tiles, it produces a flat wine bottle silhouette with a design pressed into the glass surface. The mold measures 6.5 inches long by 4.5 inches wide by 1.5 inches tall.

A pre-fused or sheet glass blank is placed over the mold and fired so the glass softens and drapes over the neck form by gravity. This mold works with standard wine bottles, COE96, and COE90 fusible glass, and is reusable across many firings when primed and cared for properly.

What does the Neck Only Bottle Slumping Mold make?
It shapes the neck area of a flat bottle silhouette in one firing. Combined with a Creative Paradise textured fusing tile, the result is a flat wine bottle with a carved design pressed into the glass.

How does slumping work with this mold?
A pre-fused or sheet glass blank is laid over the mold. During firing, the glass softens and drapes down over the neck form by gravity, taking on the bottle neck profile. No frit filling is required.

What COE glass can I use with this mold?
Any COE. Ceramic slumping molds are COE agnostic, so the same mold works with standard wine bottles, COE96, or COE90 fusible glass. Match your firing schedule and anneal temperature to the glass you are using.

How do I prep the mold before slumping?
Coat the mold 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 glass on the mold so the finished piece releases cleanly.

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 on the mold so the piece releases cleanly.
• Place a pre-fused or sheet glass blank over the mold form. No frit filling is needed for slumping.
• Pair with any Creative Paradise textured fusing tile to add a carved design to the flat bottle surface before or during firing.
• The mold is COE agnostic and works with standard wine bottles, COE96, and COE90 fusible glass. Adjust the anneal soak temperature for your glass: 950 F for COE96, 900 F for COE90.
• 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 Schedule (COE96):

*Segment 4 is the anneal soak at 950 F for COE96. If using COE90, adjust this temperature to 900 F.
