Ann Sacks just keeps expanding the world of tiles for us. Even if you’re not planning your own Turkish spa (and why not?), these Iznik tiles are manufactured with the same unique hand-crafted techniques that were used in the 16th century to adorn Ottoman temples. The tiles are made of 85 percent quartz so the finish is satiny and glasslike, and they form a fanciful pattern right out of Coleridge’s “Kubla Khan.”
