Note 1493 — COBALT, ZAFFER, SMALT.
William Johnston translation
How early manufactories for blue paint were erected beyond the boundaries of Saxony and Bohemia I do not know, as I have found no information on that subject. We are however told by Calvor, in Beschreibung des Maschinenwesens am Oberharze, ii. p. 202, that a person was engaged to superintend the blue-paint-manufactory at St. Andreasberg in the year 1698.
