Tiles made of glazed hard-paste porcelain with straight edges and corners. The product must feature a completely vitrified ivory coloured body and water absorption values of less than 0.5%. There must be a shallow box pattern on the back of the tile to facilitate its perfect adhesion to the application surface. The surface faithfully reproduces the uneven appearance of the handmade terracotta pieces. The edges are slightly rounded, as in the ancient terracotta; the colours are warm and variegated with shadings typical of materials from wood firing kilns. The material must have the properties of chemical and physical resistance for the materials of the BIa group, in accordance with standard ISO 13006, and meet all the product requirements set forth in the ISO 10545 standard. All the technical specifications must be checked according to testing methods carried out in compliance with the ISO 9001 standards.
