Note 197 — Chapter V · (XIX.)
Louisa S. Maclehose translation
Travertine, next to marble, makes when burnt the whitest lime (see § 30, ante, p. 86). From this lime the fresco white, called bianco Sangiovanni, is made, and Cennini gives the recipe for its preparation in his 58th chapter. The ordinary lead white (biacca) cannot be used in fresco.
