Marianne is a collection of crystal vases designed by Michele De Lucchi for Poltrona Frau.Elegant, luxurious, and unique, these two models of vases recreate a piece of design and art, thanks to the method of blowing with which they are made. Using an open mold formed of steel strips, the incandescent glass is blown into the mold at different intensities, resulting in a slightly different movement which makes each vase subtly yet noticeably different in shape.
