This supplement includes a thorough discussion of the special requirements in the dyeing of loose cotton, cotton yarns, fabrics, hosiery, linen and half-linen fabrics, China-grass, jute and artificial silk, as well as machine-dyeing. Digitized in its entirety, the work contains ten pages of sample swatches, plus much commentary.

Its main products were dyes, drugs, and cosmetics, though after 1945 Cassella shifted from its former primary focus on dyes to pharmaceuticals and cosmetics.
