It's hard to imagine, but this art is actually made into the glass and is reproduced with every slice taken off.
Murrine is an Italian term for colored patterns and images made in glass cane, which is a long rod of glass. Images are revealed when the rod is cut in cross-sections, much like a loaf of bread.
Art can take on the form of shapes and patterns, or even create a complete portrait.
It's made by layering different colored molten glass around a core, then stretching it into a rod.
The rod is sliced into pieces which are all identical when cut down the cross-section.
The process isn't new. It was first seen in the Middle East about 4,000 years ago, then was seen again by Venetian glassmakers in the early 16th century.
