Limestone is a collection of glazed porcelain tiles inspired by limestone composites, with rich designs which applies innovative manufacturing processes to call on the nuances and reflections of the composites and inlays typical to these surfaces. The technological innovation applied in Roca's printing techniques makes it possible to take care of micro-details in each piece, such as the play of metallic reflections and the changes in shine typical of the micas and particles common in these materials, which lend a subliminal nuance of quality to a very realistic presence.
