Bowl Glazed with Deep Ocean Sediments
Massachusetts ceramics artist Joan Lederman glazes her work—including this bowl—with deep sea sediments. Some contain tiny single-celled organisms called foraminifera. Lederman has noticed that sediments with foraminifera often make branching patterns—like the ones you see on this bowl. “I hear and feel forams roll off the sediment-filled brush,” says Lederman.
