Wall Bowls Glass wall art is quickly emerging as one of the most popular styles of art glass and is possibly the most eye-catching form of recognition. Mounted on the wall, this unique art reflects color throughout a room making a statement of sophistication and elegance. Handcrafted awards may vary slightly in finish, color and pattern. All art glass is one of a kind; sizes are approximate and no two are exactly alike. Small air bubble and flow marks are inherent in the process of fusing and slumping and are considered part of the hand made beauty of art glass.
