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 glass, these materials are homogeneous, amorphous, and of exceptional hardness. The result is a timeless design for "grand" architecture, specifically conceived for floors, both indoors and outdoors, that can be combined for a progressively decorative taste.
