Time Worn marble mosaic by Giovanni Barbieri is created by technology invented by Barbieri and used since 1999. The procedure first wears down the borders of the tiles then creates a semi-opaque natural wavy surface. Polishing then makes the surface identical to the most beautifully time worn historical floors in Italy. No matter how much usage and traffic the marble gets, its sheen and unique reflective qualities remain unaltered. The end result is a truly timeless work of art by the Italian master.

Usage includes: Walls, floors backsplashes, fireplace surrounds, shower stalls, tub surrounds, feature walls The look of ancient Rome in Calacatta marble 5 x 10 cm mosaic on mesh.
