Workshop Overview

Have you been wondering how to make your own paint from local soils and minerals? In this workshop, the instructor will cover ethical mineral foraging and participants will take minerals from their raw state all the way to finished, artist quality paint. There will be a strong emphasis on experimentation through exploring the qualities of the minerals at every stage of the process. The group will compare a variety of pigment binders including gum arabic, wax, and egg tempera, creating unique textures on paper. Participants will leave with a set of handmade watercolor paints and the knowledge to make a variety of drawing and painting materials at home in the future.

About the Instructor(s)

Carolyn Sweeney is an artist who teaches classes on mineral pigment watercolors, botanical inks, and crayon making. She runs a business called Strata Ink selling handmade inks and crayons.
