With Kosei – which means composition in Japanese – Vincent Van Duysen proposes a range of ceramic surfaces developed with pure and tactile materials, inspired by lava rocks such as obsidian and volcanic glasses, which are homogeneous, amorphous and with exceptional hardness. The end result is a timeless design conceived for "grand" architecture that can be combined for a progressively decorative taste. Kosei has been specifically conceived for floors, both indoors and outdoors.
