Olive Bottle Slumping Mold

The Olive Bottle Slumping Mold from Creative Paradise drapes a flat or fused glass sheet into the outline of an olive bottle. Place a pre-cut sheet of glass over the ceramic form and fire it so the glass softens and settles around the mold by gravity, taking the bottle contour as it cools.

The mold measures 13.5 inches long by 6.25 inches wide by 2.25 inches tall. It is suited to standard glass bottles as well as fusible sheet glass at any COE. Like all ceramic slumping molds it is COE agnostic and reusable across many firings when prepped and maintained properly.

What does the Olive Bottle Slumping Mold make?
It slumps a flat glass sheet or a standard glass bottle into an olive bottle silhouette, producing a three-dimensional bottle-form glass piece that follows the mold's 13.5 inch profile.

What COE glass works with this mold?
Any COE. The ceramic mold is COE agnostic, so it works with COE96, COE90, or other fusible sheet glass, as well as standard glass bottles. Adjust your firing schedule and anneal temperature to match the glass you are using.

How do I prep the mold before firing?
Coat the mold surface with a kiln shelf primer such as a boron nitride spray or a kiln wash such as Hotline Primo Primer, and let it dry completely before placing your glass. Re-coat between firings as needed.

Can I slump an actual glass bottle on this mold?
Yes. The firing schedule is suited to standard glass bottles as well as fusible sheet glass. If you use COE90 fusible glass instead of a standard bottle or COE96, adjust the anneal soak from 950 F to 900 F.

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 your glass so the glass does not stick.
• Place a pre-cut or pre-fused glass sheet over the mold, sized to span the 13.5 inch by 6.25 inch footprint and drape fully into the form. You may also slump a standard glass bottle directly on the mold.
• The mold is COE agnostic. Use a slump schedule matched to your glass, adjusting the final anneal soak for your COE.
• Let the kiln cool fully before removing the slumped piece. Re-coat the mold with primer as needed between firings.

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 (COE96):

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