Petra Krausová – part of Lasvit's team of in-house designers – created the Cassia collection with an optical mould made from ribs of metal. Bubbles of glass were blown into the mould, where the molten material was able to flow past the ribs and form bulbous shapes.
With this process, each of the pendants has a slightly different form. Krausová also used a variety of techniques to produce an assortment of finishes, which would be visible both with or without the light bulb illuminated inside.
Some were sand-blasted to become translucent, others smoked and then cooled to form a cracked effect, and a few were hand-painted with a thin coating of platinum.
Krausová was asked to design the lights for an installation at this year's Maison&Objet trade fair in Paris.
She based her idea on the night sky, and programmed a cluster of the lamps to automatically glow and dim at different times to create a constellation of twinkling lights.
