Hexagon Pattern Bar Dam Casting Mold

The Hexagon Pattern Bar Dam casting mold from Creative Paradise is a large ceramic dam for casting a single glass pattern bar. The inner cavity measures 8.5 inches long by 2.5 inches wide and 1.25 inches deep, giving a substantial casting space for building layered bar work. The outer mold footprint is 9.5 inches long by 4 inches wide by 2.5 inches tall, and the fill weight is 680 grams.

Like all ceramic casting molds, this one is COE agnostic. Fill the cavity with layers of colored frit, sheet scrap, or billets and fuse them into a solid bar. The resulting bar can be sliced to reveal the cross-section and used in pattern bar applications, mosaic insets, or decorative design elements. As a kiln casting mold it is reusable across many firings when prepped and cared for properly.

What does the Hexagon Pattern Bar Dam make?
It casts one solid glass bar with a cavity 8.5 inches long, 2.5 inches wide, and 1.25 inches deep. The finished bar can be sliced to expose layered patterns for use in pattern bar work or decorative applications.

What COE glass can I use in this mold?
Any COE. Ceramic casting molds are COE agnostic, so the same mold works with COE96, COE90, or other fusible glass. Match your firing schedule to the glass you are using.

How much glass do I need to fill this mold?
Creative Paradise lists about 680 grams for a full fill. Weigh your glass before loading and test a first run when the result matters.

How do I prep the mold before casting?
Coat the cavity 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 adding glass so the glass does not stick.

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 casting schedule suited to your glass and kiln.

• Prime the cavity with a boron nitride mold primer such as ZYP Boron Nitride Mold Primer, or a kiln wash, and let it dry completely before adding glass so the glass does not stick.
• Fill the cavity with layers of colored frit, sheet scrap, or billets to build up your pattern. The fill weight is approximately 680 grams.
• The mold is COE agnostic. Use a full fuse schedule matched to your glass, adjusting the anneal soak for your COE.
• Let the kiln cool fully before removing the cast bar. 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.

Full Fuse (COE96):

*Segment 3 is the anneal soak at 950 F for COE96. If using COE90, adjust this temperature to 900 F.
