Bullseye Glass Molds

This category gathers Bullseye Glass Company kilnforming molds for COE 90 fused glass, including slumping molds, drop out rings, ball surface molds, and platter forms. Shapes span simple round and square slumpers, oval dishes, classic bowls, channel plates, lamp benders, and specialty profiles like Origami and Flower molds. Sizes run from small dessert dishes to wide platters and large drop rings.

What Bullseye glass molds are

These are ceramic kilnforming molds shaped to receive fused glass during the slumping or drop firing stage. After you tack or full fuse a blank, the mold gives the finished piece its bowl, plate, platter, or sculptural form. They are profiled for Bullseye COE 90 sheet, frit, and stringer work and suit any compatible 90 COE glass.

What's in this category

Every mold listed here is made by Bullseye Glass Company. Slumpers include classic bowls, round and square slumpers, soup bowls, oval dishes, plain plates, and square platters, plus profiles like the Lamp Bender, Lamp Bender Conic, Channel Plate, Circle in Square, Oval in Rectangle, Double Curve, Origami, and Flower molds. Drop out rings are stocked in a range of diameters for free form dropped vessels, while ball surface molds produce domed, hemispherical results. Nesting plates and teardrop forms fill out the sculptural side.

Choosing a size and shape

Match the mold opening to the size of the fused blank you plan to slump, allowing room for the glass to relax into the form. Smaller round slumpers and classic bowls suit individual serving pieces, while platters, large ovals, and double curve molds are sized for centerpieces. Drop out rings need a kiln post setup that lets the glass droop through the opening, so confirm your kiln has interior height for a larger ring.

Preparing and firing

Apply kiln wash or a boron nitride coating to the working face before each firing, and follow the slumping schedule Bullseye publishes for the specific mold. The ceramic faces release cleanly when prepped well, and the molds can be used repeatedly with periodic re-coating. Slumping happens at lower temperatures than full fusing, so program a separate firing once your blank is ready.

Uses

Makers reach for these molds for fused glass bowls, plates, platters, sushi sets, candle holders, suncatchers built on dropped forms, and sculptural work shaped by ball surface and drop out rings.
