7 - Waterford (R) Evolution 11" red and amber ginger vase. Two of the most difficult colors for a glass blower to work with are red and orange. The colors are naturally unstable in the molten glass stage, demanding extreme skill and knowledge when fusing the glass together to create the art piece. The chemical compound giving these luscious reds their color is real gold! This vase is a unique shape that is great as a stand alone piece or with flowers.
