Avventurina is an ancient technique of Venetian glass-making, in which tiny pieces of copper are infused into the glass mixture for the unique sparkling effect that is characteristic of authentic Murano Glass. Using lampworking method master artisans heat up specially made glass canes produced by Murano Glass factories, then dip the blob of glass into avventurina shavings, then continue to twist and shape the glass into the design they want to achieve, sometimes also using sterling silver foil, gold foil and other additional accents to highlight the play of colors and create a truly unique piece of authentic Murano Glass. Avventurina glass beads, jewelry, rings, earrings are some of the most recognizable works of Murano Glass.
