Popular as a souvenir from Okinawa, firefly glass is a perforated glass bead made using a molding technique called burner work, similar to glass beads. Artisans melt each piece of colored glass and roll it onto an iron core. They then layer silver leaf on the molten glass, which is like a syrup, to create the beautiful colors using a special technique. *This is a luminescent (phosphorescent) type that glows in the dark. It glows in the dark (phosphorescent) by absorbing light such as sunlight.
