Mixed Plain Pendants Mold

The Mixed Plain Pendants mold from Colour de Verre casts three shapes in a single firing: a round disc, a square, and an oval. The finished round measures 1-1/4 inches in diameter, the square is 1-3/8 inches, and the oval is 1-1/4 inches by 1-5/8 inches. Each shape has clean lines and works well as a pendant blank, brooch base, or bracelet piece.

Fill weights run 12 grams for the round cavity, 15 grams for the square, and 14 grams for the oval. Each piece can be cast plain or decorated with frit, stringers, or dichroic glass laid into the cavity before firing. Like all ceramic casting molds, this one is COE agnostic and reusable across many firings with proper prep.

What does the Mixed Plain Pendants mold make?
It casts three pieces in one firing: a 1-1/4 inch round disc, a 1-3/8 inch square, and a 1-1/4 by 1-5/8 inch oval. They are sized for pendant blanks, brooches, and bracelet embellishments.

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 per cavity?
Colour de Verre lists about 12 grams for the round, 15 grams for the square, and 14 grams for the oval. Weigh your glass and test a first run when the result matters.

How do I prep the mold before casting?
Prime all three cavities before every firing with a mold primer and let it dry completely before adding glass. Colour de Verre recommends ZYP BN Lubricoat or Hotline Primo Primer for these molds.

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 the Colour de Verre project sheet for this mold.

• Prime all three cavities before every firing. Colour de Verre recommends ZYP Boron Nitride Mold Primer or Hotline Primo Primer. Let the primer dry completely before adding glass.
• Fill each cavity with frit, crushed glass, or small pieces of sheet glass. Stringers, dichroic pieces, or additional frit can be laid into the cavity to customize each cast piece before firing.
• The mold is COE agnostic. Use a full fuse schedule matched to your glass and adjust the final anneal soak for your COE.
• Let the kiln cool fully before removing the cast pieces. Re-prime the cavities before each subsequent firing.

Suggested Firing Schedule

This is a suggested starting point, not a guarantee. Every kiln fires differently. Follow the Colour de Verre project sheet for this mold and test a small run first.

• Heat no faster than about 350 F (195 C) per hour.
• Fire to no more than about 1450 F (785 C).
• Add a controlled cool with an anneal soak suited to your glass: about 950 F for COE96, or about 900 F for COE90.
