ART 36 is a polished soluble salt tile in 60x60 cm with a marble look, built around an octagonal frame. Inside the frame, cream and pale grey rays fan out from the centre in a starburst, edged by grey and cream bands; the corners carry beige shapes with grey circles, which meet across laid tiles as a repeating star-and-circle motif. For choosing, the key specs are glossiness above 90% (gloss meter 60°), water absorption < 0.05% (ISO-10545-3), breaking strength > 1700 N and modulus of rupture > 40 N/mm2 (ISO-10545-4), and surface abrasion resistance Class PEI 4 (EN 154). It rates Class 5 for stain resistance (ISO-10545-14), passes frost resistance (ISO-10545-12) and holds Class A1 - A1 fl for reaction to fire.
