On Sunday I returned to work on the Agate still life watercolor begun in January. (I’ve developed a habit of setting aside partially finished paintings and I’m making a promise to myself to stop doing this.) Here is my last posting:

And here is the finished painting.
I found it very soothing to build up the various rings with glazes using matching and contrasting colors. To add more texture, I applied salt to the wet paint in places. After it had dried, I scribbled with a black Prismacolor pencil on the outer layer and darkened some of the rings. To finish, I flecked on spots of copper metallic paint using a toothbrush.
Paints included raw sienna, burnt sienna, quinacridone red, Payne’s gray, cerulean blue and Prussian blue.

I like adding salt for texture too. Your completed piece turned out really nice! Good work! ❤️
