Daniel Smith Bloodstone Genuine is a pigment I did experiment with a little earlier this year. It really does race around when it hits the water and then proceeds to offer up interesting texture. Here I have combined it with Winsor & Newton Quinacridone Gold.
Yesterday for my watercolour class it provided a great example of creating using a sprayed paper first and then spattering pigment with a brush .
We also tested how well it would lift out.
