Traditional Ottoman tiles made from recycled glass and coloured with natural minerals and oxides. The glass is then stamped in a mold and fired in a linear kiln. The regularity of their crystal structure makes cutting like a hot knife through butter with little or no wastage. The smooth surface reflects light to produce vivid color and life while the wide range of shades and tones make this an excellent choice for all levels of mosaic. Each tile is 1 inch square (25mm), 1/6 inch (4mm) thick and 500 tiles = ± 1 square foot and 1kg (2.2 lbs) = ±300 tiles.
