The Rialto Green Glass Fish Set includes large and small glass sculptures created in the Venetian tradition of glassblowing. The green fish sculptures require special tools to twist certain aspects of the pieces when the glass is beginning to thicken, such as the tails and the lips. The fins are added by hand, a precise effort that takes great skill and experience in order to know when the glass is the perfect temperature so that they will adhere rather than melt. Each piece will have slight variations, which makes these green decorative accessories unique.
