The Snowflake 15 mold from Colour de Verre casts two snowflakes per firing, each measuring 3.75 inches (9.5 cm) across. The mold footprint is 9 inches by 5 inches (23 x 13 cm), and each cavity calls for about 20 grams of frit. The design is the most intricate in the Colour de Verre snowflake line, with larger, more detailed flake arms suited to holiday ornaments, window accents, and embellishments on festive platters, candle holders, and votives.
Like all ceramic casting molds, the Snowflake 15 is COE agnostic. Load the cavities with frit, fire to shape, and the glass takes the form of the cavity. Adding dichroic frit or flakes to the mix produces extra sparkle in the finished pieces. The mold is reusable across many firings when primed before every use and cared for properly.
What does the Snowflake 15 mold make?
It casts two snowflakes, each 3.75 inches (9.5 cm) across, in one firing. They work well as Christmas tree ornaments, holiday window hangings, or as accents on platters, candle holders, and votives.
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 20 grams per cavity. Weigh your frit before loading and test a first run when the result matters.
How do I prep the mold before casting?
Colour de Verre requires priming before every use. Apply a boron nitride primer or kiln wash to the cavities and let it dry completely before adding glass. See the Working Notes below for recommended primers.

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 cavities before every use with ZYP Boron Nitride Mold Primer or Hotline Primo Primer and let each coat dry completely before adding glass. Colour de Verre requires priming before every firing.
- Fill each cavity with about 20 grams of frit. Adding dichroic frit or flakes to the mix can produce extra sparkle in the finished snowflakes.
- The mold is COE agnostic. Use a firing schedule matched to your glass and adjust the anneal soak for your COE.
- Let the kiln cool fully before removing the cast pieces. Re-prime the mold before the next firing.
