Dichroic Lampwork Glass
Lampworking is a type of glasswork where a torch or lamp is used to melt thin rods of glass over an open flame. When the glass is in a molten state, the glass is wrapped around a thin metal rod, which creates the hole. The bead is formed by blowing and shaping with tools and hand movements.
Dichroic shows two or more different colors when viewed from different directions.
