Aquamarine is created through the use of copper and cobalt, and ruby red is achieved through the use of a gold solution as a coloring agent.
Most Murano beads are made using an air pump burner lampworking or torch and mandrel technique.
After the bead is slowly cooled, it is removed from the rod, resulting in a hole for eventual stringing as jewelry.
To produce this tiny bead, hollow tubes of colored glass are formed, then chopped and re-fired for smoothness and shade.
To produce these beads with stripes of color and spirals, glassmakers lay canes of glass down and pick them up with a blow-pipe.
