Sight Unseen is on the ground at the Milan Furniture Fair this week and we’ll be bringing you loads of coverage next week, plus moment-by-moment round-ups on our Instagram Stories. But until our rounds here are done, we’ll be featuring quick hits from some of our favorite things that caught our eye. Our pick today? After five years, Dzek — you know, the makers of your favorite terrazzo kitchen — returned to the fair with another architectural material with a vast applications: Called Ex-Cinere, it’s a collection of tiles — with serious 70s vibes — developed in collaboration with Formafantasma, stemming from the Dutch-based duo’s longtime exploration into volcanic rock. “Although Volcanic ash and basalt rock may appear inert, their high metal oxide content makes them complex and unpredictable to work with,” the press materials reveal. “Three years of exploding, imploding, cracking and caving were endured before ExCinere’s careful balance of porcelain body, ash glazes, firing temperature and method was achieved.” The colors were “achieved by mixing varying quantities, particle sizes and densities of volcanic matter, resulting in surfaces that are evocative of the dynamic landscape from which they come.” On view at Via Venina 85.
