cf. F. Ferrari, Ettore Sottsass Tutta La Ceramica, Turin, 1996, p. 119, pl. 511.
The Ceramics of Darkness (ceramiche delle tenebre) series was created in reaction to Sottsass' potentially fatal illness that he suffered in 1962. The use of color, in particular the dominance of darkness over light reflects his fears while the cylindrical form is representative of the violet-blue night lighting in the hospital. This series was exhibited at Il Sestante gallery in 1963 in Milan.
