Beautiful, high-fired vitreous glass with a permanent mother of pearl finish. These tiles stand up to extreme weather exposure, chemicals, and salt. The colour is UVA- and frost-resistant, making this an ideal tile for outdoor applications or for demanding conditions such as pools, spas, commercial kitchens, and toilets. The iridescent finish reflects light and, thus, brightens dark spaces. Each tile is 20mm² and 4mm thick
