Last year, French designers Ronan and Erwan Bouroullec delighted us with a collection of vases made in collaboration with Finnish brand Iittala. The range was titled 'Ruutu', a Finnish word meaning diamond or square which aptly described the pieces’ shapes. Colourful and geometric, the collection was a good demonstration of the brothers’ way with colour and simple forms.

Now the brothers are back with a new exploration of the medium. This time, however, they have taken glassblowing to a new extreme, creating oversized shapes that combine colour and texture in a novel way. Working again with the Finnish glassmaker (which also produced Alvar Aalto’s legendary glassworks), the Bouroullecs created a collection of 14 unique pieces in sizes that pushed the manufacturing possibilities of the material, with heights ranging from 35–63cm high.

To be able to produce vases in this size, the thickness of the glass was increased, resulting in a textured finish, which became an integral part of the design. The set features clear glass as well as olive green and amber colours – when combined the three shades create a series of juxtapositions and shadows that extend the collection’s aesthetic possibilities.
