Multicolor Cane Vessel in Violet by Michael Hermann and Gina Lunn. Beautiful cane patterns lined in specific colors to create a dazzling optical effect when the viewer looks through the piece. The artists first create patterned glass rods called cane, cut them into individual cross-sections, and lay out a specific color pattern. This pattern is then twisted over a core of clear glass. Primary colors used in this vessel are violet, blue, and amber. The effect is stunning.
