From an article by Brian Sandford for Pasatiempo:
Willy Bo Richardson says: “The first step is laying down that first ground color. Anything can happen at any point; if I feel like I know what I’m doing too much, then I know I’ve put myself in a corner. As long as I feel like there’s a mystery and exploration and unknowns, I know it’s going well. When I get to the final glaze layers, it’s just a call and response: A color comes to mind, I mix it, and as I’m mixing it, anything can change. It can turn out to be a different color.”
