The nature of light is elusive. When it shines through crystal or glass, light appears in the form of splintered shapes and prismatic reflections that are beautiful to behold but challenging to re-create. Learning how to observe light and its effects on glass will help you see fabulous distorted patterns and contrasting values. You'll find that even the simplest piece of glass contains extraordinary shapes within shapes. You'll appreciate the soft and hard edges, perfect for watercolor. And just when you think you have a pleasing variety of shapes and values, you'll tilt your head and discover the prism effect—a beautiful rainbow shining through. I guarantee you'll never look at glass, cut crystal or reflective surfaces the same way again.
