Herman and Otto Natzler, Form and Fire: Natzler Ceramics 1939-1972, The Smithsonian Institution Press, Washington, D.C., 1973, p. 75, no. 111 (not illustrated)'One of the first pots Gertrud made in this particular closed form. The glaze, another first, shows very severe fire marks, for I attempted to make use of the explosive force produced by reducing agents when they are ignited. No. 112, from the same fire, shows the effects even more extensively. The "skinning" of the glaze is quite characteristic and a deliberately aimed-for byproduct of the process.'-Otto Natzler, Form and Fire: Natzler Ceramics 1939-1972, p. 75
