There are few objects whose function allows for as many design possibilities and material variations as vases. Pisano vases are pieces that showcase any bouquet beautifully. Pisano is made from colored glass using a technique called overlay glassblowing, resulting in stunning color combinations. The rim of the Pisano vase is hot polished. Stubborn edges, lime deposits, and plant residues can be removed with vinegar cleaner or denture cleaner. Do not wash your vase in the dishwasher, as this may cause what are known as thermal shocks.
