White lead had been used since Roman times and following the middle ages the so called Dutch process of manufacture basically involved strips of lead in jars of acetic acid and kept warm in fermenting animal manure. A variation of this Dutch process made a particularly dense and pure pigment that was noticeably better than regular Flake White. Competition with Titanium white lead to a lowering of prices and a lowering of quality that had the famous art materials writer Max Doerner complaining in the 1930’s of the decline of Cremnitz White. While the best grades are still labeled Cremnitz, they are not comparable with the original.
