Beaches remind us of simple pleasures--swimming in the surf, building sand castles, and collecting smooth, opalescent beach glass. These once man-made objects, perhaps glass bottles or insulators, were broken, rolled and tumbled by the waves, and smoothed into something completely different, something--almost--natural again. Beach glass is found art. Why we take such pleasure in these bits and pieces of manufactured materials reclaimed by nature may be something to contemplate while enjoying Treasures from the Tide--the author surely has, and she conveys that pleasure in playful, organic sculptures that come to life in the interplay of colors and shapes and their interaction with the sand and surf they came from. The sense of a moment in time captured in these photos is like an insect captured in amber, and, in this book, beach glass becomes just as precious.
