The hand-blown craftsmanship of the Sommerso technique gives this and all Sommerso vases a strikingly smooth look. The translucent nature of the vase allows light to pass through the outer layers of the glass, illuminating the colorful center. The detailed artistic process of glass blowing causes slight variations in each piece making no two pieces identical. Please note, because this item is handblown, it is not uncommon for air bubbles to be present.
