Medium Dome Paperweight Casting Mold

The Medium Dome Paperweight mold from Creative Paradise casts a single dome-shaped glass piece in one firing. The inner cavity measures 4 inches in diameter and 1.5 inches deep, producing a finished dome about 4 inches across, while the mold body itself measures 5.25 inches in diameter and stands 2.75 inches tall. The result is a solid dome form suited to paperweights and freestanding display pieces.

Like all ceramic casting molds, this one is COE agnostic. Fill the cavity with frit, small billets, or stacked sheet scrap and fuse to the dome shape. The manufacturer lists a fill weight of about 400 grams. As a kiln casting mold it is reusable across many firings when prepped and cared for properly.

What does the Medium Dome Paperweight mold make?
It casts one dome-shaped glass piece measuring about 4 inches in diameter and 1.5 inches tall, in a single firing. It is well suited to paperweights and freestanding decorative pieces.

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?
The manufacturer lists about 400 grams per casting. Weigh your glass and test a first run when the result matters, as fill weight can vary with glass density and how you load the cavity.

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. 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, small billets, or stacked sheet scrap. With 400 grams of glass, pack the cavity fully for an even dome profile.
• 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.
