NPT StoneScapes® Touch of Glass AQUA WHITE TOUCH OF GLASS 1/2 Aqua White Pebble Pool Finish .5 Parent Kit. StoneScapes Touch of Glass Aqua White creates medium blue water color and is comprised of modified white Portland cement which has been colored with aqua blue pigment and natural white quartz pebble aggregates with pronounced Sky Blue glass bead accents. The glass bead accents enhance the water color by adding additional pops of color and contrast that only colored glass bead can do. The beauty of this finish comes from the shade and color variations inherent in natural materials.
