Diamond Glasslinks (Set of 2)

The Diamond Glasslinks mold set from Colour de Verre includes two ceramic casting molds that together cast twelve Diamond Glasslinks in a single firing. That is exactly the number of links needed to complete a necklace, making it a practical set for jewelry work. Each of the two molds measures 5-3/4 inches by 3-5/8 inches, and each cavity takes 3 grams of fine or powdered frit.

This design fires at a lower peak than a standard full fuse. Colour de Verre specifies a target of about 1335 to 1350 F (725 to 730 C), held for 25 to 30 minutes before annealing. That lower peak is intentional and specific to the Glasslinks form. Like all ceramic casting molds, these are COE agnostic and reusable across many firings when properly primed and cared for. Completed links are joined using metal links, large oval jump rings, or jump rings paired with double-looped eye pins.

What does the Diamond Glasslinks Set of 2 make?
The two molds together cast twelve Diamond Glasslinks per firing, enough to complete a necklace in one session. Each mold contributes six links.

How much frit does each cavity need?
Colour de Verre lists 3 grams of fine or powdered frit per cavity. The full two-mold set uses 36 grams total per firing.

What COE glass can I use?
Any COE. Ceramic casting molds are COE agnostic, so the same molds work with COE96, COE90, or other fusible glass. Match your firing schedule and anneal soak temperature to the glass you are using.

How are the finished Glasslinks connected?
Completed links can be joined with metal links, large oval jump rings, or jump rings paired with double-looped eye pins using standard jewelry techniques.

How do I prep the molds before casting?
Prime every cavity before each firing with a boron nitride mold primer and let it dry completely before adding frit. Colour de Verre recommends priming before every use.

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 every mold cavity before each firing with a boron nitride mold primer. Colour de Verre recommends ZYP Boron Nitride Mold Primer or Hotline Primo Primer. Let the primer dry completely before adding frit so the glass releases cleanly.
• Fill each cavity with 3 grams of fine or powdered frit.
• The molds are COE agnostic. Match your firing schedule and anneal temperature to the glass you are using.
• Heat no faster than about 350 F (195 C) per hour to protect the mold and allow even heat penetration.
• Fire to about 1335 to 1350 F (725 to 730 C) for this design. This is lower than the general Colour de Verre ceiling of about 1450 F (785 C) and is specific to the Glasslinks form. Do not exceed this range.
• Hold at peak temperature for 25 to 30 minutes, then cool with a controlled anneal soak. A standard anneal point is about 950 F for COE96 or about 900 F for COE90.
• Let the kiln cool fully before removing the links. Re-prime both molds before the next use.

Colour de Verre Suggested Firing Schedule

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

• Heat rate: no faster than about 350 F (195 C) per hour
• Peak temperature: about 1335 to 1350 F (725 to 730 C)
• Hold at peak: 25 to 30 minutes
• Anneal soak: controlled cool to an anneal hold at about 950 F for COE96 or about 900 F for COE90
