Drop Center Bottle Slumping Mold

The Drop Center Bottle Slumping Mold from Creative Paradise is designed to slump a standard 1.75 liter glass bottle flat over its ceramic form, with the center of the bottle dropping into a recessed 6 inch by 3 inch pocket. The overall mold footprint is 17 inches long by 6.25 inches wide by 3 inches tall, giving the form enough length to accommodate a full-size bottle in a single firing.

The drop center recess measures 6 inches long by 3 inches wide by 1 inch deep, so the finished piece has a sunken center section that adds dimension and can serve as a serving tray, cheese board, or decorative wall piece. Like all ceramic kiln molds, this one is COE agnostic and works with recycled soda-lime bottles, COE96, and COE90 fusible glass. The form is reusable across many firings when properly primed and cared for.

What does the Drop Center Bottle Slumping Mold make?
It slumps a 1.75 liter bottle flat against the mold, with the center dropping into a 6 inch by 3 inch by 1 inch deep recess. The result is a flattened bottle with a dimensional sunken center section.

What size bottle fits this mold?
Creative Paradise suggests a 1.75 liter bottle. The mold is 17 inches long and 6.25 inches wide, sized to fit a full large-format bottle.

What COE glass can I use with this mold?
Any COE. The mold works with standard soda-lime glass bottles, COE96, and COE90 fusible glass. Adjust the anneal soak to match your glass: 950 F for standard bottles and COE96, 900 F for COE90.

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 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 so the glass does not stick.
• Place the 1.75 liter bottle over the prepared mold, centered over the drop recess, before firing.
• The mold is COE agnostic. Use a slumping schedule matched to your glass, and adjust the final anneal soak for your COE: 950 F for standard soda-lime bottles and COE96, or 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 slump schedule for standard glass bottles and COE96. Every kiln fires differently. Test a small run and adjust for your glass and kiln.

Slump Schedule:

*Segment 4 is the anneal soak at 950 F for standard soda-lime bottles and COE96. If using COE90, adjust this temperature to 900 F.
