‘Twisted’ whilst the glass is still malleable and soft, Sacco recalls the shape of a crumpled sack. Once cooled the vase preserves this sense of motion which is further enchanted by the iridescent sheen that follows its curves. This vase is handcrafted and signed. The process of Iridazione (to make a surface iridescent) gives to the glass a visual pearl-like effect. This chemical process is generated when the glass is still soft and incandescent.
