Details

The fine frit grade resembles river silt and talcum powder. Paul Trautman 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.
