Penumbra

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 colours and effects. This sample includes some clear glass; you can see a mirror finish at the edges. There are approximately 11 rods per pound.

Working Tip: A reformulation of one of Paul’s old favorites. This reactive “lunar” blue reduces and oxidizes into a range of colours, including blues, greens, purples, and silvery shades. Heat changes her, as does encasement.
