There are few items whose function allows for as many design possibilities and material variations as vases. Pisano vases are objects that showcase every bouquet. Pisano is made from colored glass using a technique called overlay glassblowing. This results in the most beautiful color combinations. The rim of the Pisano vase is hot-melted. 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 could lead to what are known as thermal shocks.
