The Alchemy of Fire and Light
The Alchemy of Fire and Light
Most people see glass as something cold, hard, and functional. But in my workshop on the Isle of Arran, I see it as a liquid held in suspense.
Glass fusing is the art of using extreme heat to defy the nature of the material. By layering pieces of specialized glass—like the crystal-clear Bullseye Tekta—and heating them in a kiln, I can "stitch" separate pieces of glass into a single, unified masterpiece.
The Magic of the "Bite" (Temperatures)
The kiln is where the real drama happens. Depending on the "voice" I want the glass to have, I play with the heat:
The Full Fuse ($804^{\circ}\text{C}$): At this temperature, the glass loses its memory. It melts together into a perfectly smooth, glossy surface. It’s thick, tactile, and glows with a liquid depth.
The Contour Fuse: By dropping the temperature, I can make the glass "tack" together. This keeps the 3D texture—you can feel the ridges of a thistle or the edge of a coastline.
The Slump: This is where we turn flat art into functional form, melting the fused glass over a mold to create bowls that catch the Scottish sunlight.
Why Fused Glass is Different
Unlike "blown glass" (the kind with the long pipes and glowing blobs), fused glass is about precision and layering. It’s more like marquetry or painting. I can place a single grain of gold mica or a sliver of Rose Silver enamel exactly where I want it.
When that kiln door opens after a 24-hour cycle, you aren't just looking at glass anymore. You’re looking at captured light.
