Millefiori, or Thousand Flowers, are bead-like pieces of glass cut from long colored rods. The Millefiori are mainly used for making beads and jewelry. These beads are processed in the open flame into jewelry. The loose beads can be fused together using, for example, a glass plate. Look after! Because the beads have a COE of 104, which means they cannot be fused with all glass.
