Paul has reformulated one of his old favorites and dubbed it Penumbra, from the astronomy term for a partial eclipse shadow. Penumbra is a reactive, striking "silvered" cobalt blue, which reduces and oxidizes for a range of colors and effects. This sample includes some clear glass; you can see a mirror finish at the edges.
