Flag Bottle Slumping Mold

The Flag Bottle Slumping Mold from Creative Paradise transforms a recycled glass bottle into a flat, flag-themed patriotic dish in a single kiln firing. The mold measures 13.5 inches long by 6.25 inches wide by 2.25 inches tall, sized to accommodate the 750 mL bottle shown in the manufacturer example. The glass softens over the mold surface and conforms to the flag-themed form by gravity.

To use this mold, a clean bottle is laid on the prepared mold surface and fired until the glass relaxes into the form. As a ceramic slumping mold it is COE agnostic and reusable across many firings with proper care and re-coating between uses. Standard glass bottles, COE96, and COE90 fusible glass all work with this mold; adjust the final anneal temperature to match the glass you are using.

What does the Flag Bottle Slumping Mold make?
It slumps a glass bottle into a flat, flag-themed patriotic dish in one firing. The manufacturer example uses a 750 mL bottle.

What size bottle works with this mold?
The manufacturer example shows a 750 mL bottle. The mold surface measures 13.5 inches by 6.25 inches, so check your bottle dimensions against those before loading the kiln.

Can I use any glass bottle, or only fusible glass?
The mold works with standard glass bottles as well as COE96 and COE90 fusible glass. If using COE90 rather than a standard bottle or COE96, adjust the anneal temperature to 900 F.

How do I prepare the mold before slumping?
Coat the mold surface with a boron nitride primer or kiln wash and let it dry fully before placing the bottle. Re-coat between firings as needed.

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 such as Hotline Primo Primer, and let it dry completely before placing the bottle so the glass does not stick.
• Lay a clean, dry bottle on the prepared mold surface. The manufacturer example uses a 750 mL bottle; check that your bottle fits within the 13.5 inch by 6.25 inch mold surface.
• The mold works with standard glass bottles, COE96, and COE90 fusible glass. Match your firing schedule to the glass you are using.
• If using COE90 rather than a standard bottle or COE96, adjust the anneal soak in segment 4 to 900 F.
• Let the kiln cool fully before removing the slumped dish. 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:

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