Each Tizian is an extraordinary handcrafted objet d‘art. The vases are made in a small factory that specializes in so-called studio glass. In an artistic handcrafting process the glass is blown into shape in several layers. Metal oxide is added to the multicoloured glass, which creates beautiful and unique highlights. Small bubbles and irregularities are typical characteristics of this special glass. This unique piece should be cleaned with warm water and dishwashing liquid. Tough limescale rings can easily be removed with vinegar cleaner.
