Note 11 — APPENDIX.
Reading edition
The distinction between pastel and woad is not very clear. Schutzenberger says: “Pastel, woad, and satis tinctoria is a plant of the family of the crucifera. It would seem, however, that the term pastel as used by the old French dyers is applied to the leaves of the woad which have been fermented, formed into paste, and afterwards into balls, and which contain much blue coloring matter. And the term woad as distinguished from pastel is applied to the unfermented plant.”
