The Blossoms Casting Mold from Colour de Verre fills six flower-shaped cavities in a single firing, producing blossoms in three sizes: 3/4 inch, 1 inch, and 1-1/4 inch in diameter. Colour de Verre lists fill weights of 6, 8, and 10 grams per cavity for the three respective sizes, so you can weigh your frit and load each cavity to the right level.
Finished blossoms work well as standalone jewelry pieces such as brooches or pins, and they can be strung together for bracelets or set into larger fused projects including plates, platters, bowls, and other castings. Like all ceramic frit casting molds, this one is COE agnostic and reusable across many firings when primed and cared for before each use.
What does the Blossoms Casting Mold make?
It casts six flower-shaped blossoms in three diameter sizes in a single firing: 3/4 inch, 1 inch, and 1-1/4 inch across.
What are the fill weights for each cavity size?
Colour de Verre lists 6 grams for the 3/4 inch blossom, 8 grams for the 1 inch blossom, and 10 grams for the 1-1/4 inch blossom. Weigh your frit 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.
How do I prep the mold before firing?
Colour de Verre requires priming before every use. Coat all cavities with ZYP BN Lubricoat or Hotline Primo Primer and let the primer dry completely before loading frit.
What finished pieces can I make with the blossoms?
They work as jewelry blanks for brooches and pins, as components for strung bracelets, or as accent pieces incorporated into larger fused projects such as plates, platters, and bowls.
