Large Dome Paperweight Casting Mold

The Large Dome Paperweight mold from Creative Paradise casts a single dome-shaped glass paperweight in each firing. The finished dome measures 5.5 inches in diameter and 1.75 inches tall, making it a substantial decorative piece well suited to display on a desk or shelf. The mold itself is 7.5 inches in diameter and 3 inches tall.

Like all ceramic casting molds, this one is COE agnostic. Fill the single large cavity with frit, billets, or stacked sheet scrap and fuse it to the dome shape. Creative Paradise lists a fill weight of 411 grams. As a kiln casting mold it is reusable across many firings when prepped and cared for properly.

What does the Large Dome Paperweight mold make?
It casts one dome-shaped glass paperweight per firing. The finished piece is 5.5 inches in diameter and 1.75 inches tall.

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?
Creative Paradise lists a fill weight of 411 grams. Weigh your glass and test a first run when the result matters, as fill weight can vary with how the cavity is loaded.

How do I prep the mold before casting?
Coat the large 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. 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 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 with frit, billets, or stacked sheet scrap to reach the 411 gram fill weight. Load the cavity evenly to support a uniform dome form.
• The mold is COE agnostic. Use a full fuse schedule matched to your glass, adjusting the final anneal soak for your COE.
• Let the kiln cool fully before removing the cast 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 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 4 is the anneal soak at 950 F for COE96. If using COE90, adjust this temperature to 900 F.
