Trencadís is a distinctive form of mosaic art created by cementing together shards of broken tiles and chinaware. Also known as pique assiette or shardware, this technique allows artists to transform discarded fragments into complex visual displays. It is most famously associated with the work of Antoni Gaudí, who utilized the method to cover irregular surfaces with vibrant, durable patterns.
While glazed china and ceramics are the primary materials, artists may also incorporate glass, buttons, or shells to add texture and variety. The resulting designs can range from abstract geometric patterns to intricate pictorial scenes. This versatile medium allows for both random, spontaneous arrangements and highly structured, hybrid compositions, making it a hallmark of decorative architectural ornamentation.
