Flat Base Wine Bottle Slumping Mold

The Flat Base Wine Bottle Slumping Mold from Creative Paradise slumps a standard wine or liquor bottle into a flat serving tray with the neck raised as a built-in handle. The mold is 16 inches long, sized to accommodate wine or liquor bottles up to 750 mL, and the finished tray works well as a board for cheeses, crackers, or small appetizers.

During firing, the bottle softens by gravity on the mold surface: the body spreads flat against the base and the neck remains elevated to form a handle. The ceramic mold is reusable across many firings and COE agnostic. Keep in mind that found glass such as wine or liquor bottle glass is not tested for compatibility with fusible sheet glass, so fire the bottle on its own.

What does this mold make?
It slumps a wine or liquor bottle into a flat tray with the neck raised as a handle. The finished piece works as a serving board for cheeses or small appetizers.

What type of bottle fits this mold?
Wine or liquor bottles up to 750 mL, the standard full-size bottle. The 16 inch mold length accommodates the typical bottle profile with room for the neck.

Does the bottle's COE matter?
The ceramic mold is COE agnostic and works with any glass. Bottle glass is found glass and is not tested for compatibility with COE96 or COE90 fusible glass. Fire the bottle by itself and use an anneal soak suited to your glass. If using COE90 fusible glass instead, adjust the anneal soak to 900 F.

How do I prep the mold?
Coat the mold surface with a boron nitride spray such as ZYP, or a kiln wash such as Hotline Primo Primer, and let it dry fully before placing the bottle. 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 the bottle.
• Lay the bottle across the prepared mold, positioning the neck over the raised section. The body will spread flat and the neck will stay elevated to form a handle as the glass softens.
• Wine and liquor bottle glass is found glass and is not tested for compatibility with COE96 or COE90 fusible glass. Fire the bottle by itself, not combined with other glass.
• The ceramic mold is COE agnostic. Adjust the anneal soak temperature to match your glass: 950 F for standard bottle glass or COE96, 900 F for COE90.
• Let the kiln cool fully before removing the finished tray. 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 starting schedule for standard bottle glass or COE96, not a guarantee. Every kiln fires differently. Test a small run and adjust the schedule for your glass and kiln.

Slump Schedule:

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