The same can be said about glass: Nature invented it, man discovered it around 5,000 B.C. and has been working to improve upon it ever since.
Glass-related research still continues, and one of the most recent enhancements has been the application of specially formulated waterborne coatings to sheets of clear glass, which provides them with a variety of colors and hues. The furniture industry has been the first to adapt this concept but when the creativity of product development professionals, designers, architects and contractors becomes stimulated, it could have a range of other applications.
