These are some studies I did of seashells. I was experimenting with a very exciting ink from Parker called Quink. You brush on a layer of the blue black ink onto the paper and let it dry. Then you dip your brush or pen into bleach and draw. A very luminescent line appears. I love the glowing quality. I originally prepared my paper with a yellow ochre watercolor wash and salt resist. Then I brushed on the Quink and let the magic happen.
