Cf. A. Vecht, Black Delft, in: catalogue Gemeente musea Amsterdam Willet Holthuysen cat.322, 24 nov. 1962-15 jan. 1963, for a discussion and an illustration of a similar teacaddy No.5 signed Louwys Victorszoon or Lambertus van Eenhoorn in the Gemeentemuseum, Den Haag, in the same range of colours on black ground and with yellow mark.
"Black Delftware" is regarded as one of the finest products of the Delft faience industry. The decoration on a black ground must have been difficult technically and very expensive, hence only a small quantity of it was ever made. Oriental lacquer imported in Europe by the Dutch East India Company from around 1675 may have been the inspiration behind Delft noir.
Tea which was also expensive was often kept in luxurious teacaddies. Thus the shape of the teacaddy is derived from a precious silver prototype.
