Cabbage Leaf Mold

The Cabbage Leaf Mold from Colour de Verre casts one detailed glass leaf per firing, measuring approximately 8 inches (21 cm) in diameter. The mold itself measures approximately 10.5 inches (27 cm) in diameter, giving each leaf room to form with full detail. The result is a botanically realistic leaf suited to decorative plates, wall art, or assembled sculptural pieces.

This mold has a dual-function design. The front side casts the leaf shape, while the reverse side provides a slumping surface so you can shape each cast leaf into a gently wavy, organic form. Colour de Verre lists a fill weight of 400 grams of frit or sheet glass per firing. Like all ceramic casting molds it is COE agnostic and reusable across many firings with proper prep.

What does the Cabbage Leaf Mold make?
It casts one glass leaf, approximately 8 inches (21 cm) in diameter, per firing. The leaf replicates the natural texture and flow of real cabbage leaves.

What is the dual-function design?
The casting surface on the front of the mold forms the detailed leaf shape. The reverse side of the mold is a slumping surface, so you can place a cast leaf on it in a second firing to give the leaf an organic, wavy curve.

How much glass do I need?
Colour de Verre lists 400 grams of frit or sheet glass for this mold. Weigh your glass and test a first run when the result matters.

What COE glass can I use?
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.

What can I make by combining cast leaves?
Colour de Verre suggests tack fusing two or more leaves to create bowls, platters, or wall art. The leaves work with transparent, opalescent, or reactive glass for added visual depth.

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 the mold before every use with ZYP Boron Nitride Mold Primer or Hotline Primo Primer, and let it dry completely before adding glass.
• Fill the mold with 400 grams of frit or sheet glass. Transparent, opalescent, or reactive glass all work with this mold.
• The mold is COE agnostic. Use a fusing schedule matched to your glass type.
• For slumping, place a cast and fully annealed leaf onto the reverse side of the mold and fire a second time to shape it into a wavy, organic form.
• Tack fuse two or more finished leaves to create bowls, platters, or wall art assemblies.
• Let the kiln cool fully before removing cast pieces. Re-prime the mold as needed between firings.

Suggested Firing Schedule

This is a suggested starting schedule based on Colour de Verre's general guidance, not a guarantee. Every kiln fires differently. Follow the Colour de Verre project sheet for this mold and test a small run first.

• Prime the mold before every use and let it dry completely before adding glass.
• Heat no faster than about 350 F (195 C) per hour during the initial heat-up phase.
• Fire to no more than about 1450 F (785 C).
• Add a controlled cool with an anneal soak appropriate for your glass type and thickness, following your glass manufacturer's guidance.
• Let the kiln cool fully before removing cast pieces.
