Ginkgo Leaves Mold

The Ginkgo Leaves mold from Colour de Verre is a two-sided ceramic casting mold offering six glass leaf shapes, three cavities on each side, cast one side at a time. Side A, marked Ginkgo Leaves, holds three cavities at about 9 grams of glass each. Side B holds three cavities with fill weights of 15 grams, 7 grams, and 14 grams, providing a range of leaf sizes in one mold. The overall mold footprint is 5 inches by 8 inches, with a depth of 1.25 inches.

Fill the cavities with frit, powder, or small glass pieces and fire so the glass takes the detailed ginkgo leaf shapes. The finished pieces work well as jewelry elements, surface embellishments, or accents in larger fused projects. Like all ceramic casting molds, this one is COE agnostic and reusable across many firings when primed and cared for properly.

What does the Ginkgo Leaves mold make?
It offers six leaf designs across its two sides, cast three at a time. Side A produces three leaves at about 9 grams each, and Side B produces leaves at about 15 grams, 7 grams, and 14 grams. The finished leaves are suited to jewelry, embellishments, and decorative accents.

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 and anneal soak to the glass you are using.

How much glass do I need per cavity?
Colour de Verre lists about 9 grams per cavity for Side A. For Side B, the three cavities take about 15 grams, 7 grams, and 14 grams respectively. Weigh your glass and test a first firing when the result matters.

How do I prep the mold before casting?
Prime every cavity before every firing with a boron nitride mold primer. Colour de Verre specifically recommends ZYP BN Lubricoat or Hotline Primo Primer. Let the primer dry fully before adding glass so the glass does not stick.
