Painting with glass, then daring fire to fuse it before it shatters.

means The craft of fusing powdered or ground glass onto a metal, ceramic, or glass surface by firing at high heat to create a smooth, hard, glossy coating, often in vibrant colors.

from From "enamel," which entered English from Anglo-Norman "enamailler," itself built from the prefix "en-" (to put on) plus "amail" — an Old French word for the glassy substance. The Old French root is generally traced back to a Germanic source related to "melt," a fitting ancestry for a material that must be melted to take hold.
