Murrini are small segments of glass cut from a cane that has been layered with various stripes of glass and then heated and pulled into a length of glass cane. There are many different patterns ranging from stripes to complex squares of contrasting colours. The small pieces of cane are then inset into a hot glass bead, or in the case of the very intricate millifiori beads they are assembled and fused in a furnace.
The bead from Coppergate in York is an example of using two different patterns of striped cane sections to create a design on a base of black glass. Each cane is made individually, the two patterns used below are a green core with red and white stripes, and a green core with yellow and red stripes.
The beads measure approximately 18mm in diameter with an 8mm hole.
