[12] Early dyers were particular as to the naming of their colours. Here is a list of blues, published in 1669.—"White blue, pearl blue, pale blue, faint blue, delicate blue, sky blue, queen's blue, turkey blue, king's blue, garter blue, Persian blue, aldego blue, and infernal blue."
[13] I give here recipes for the simpler vats which can be used on a small scale. The more complicated recipes can only be done in a well-fitted dye house. I would refer the reader to those in "The Art of Dyeing" by Hellot, Macquer and D'Apligny, and "Elements of the Art of Dyeing" by Berthollet.
[14] Woad, pastel and Indigo are used in some dye books to mean the same dye, and they evidently have very much the same preparation in making.
[16] This recipe can also be used for linen, but linen takes the colour less easily than cotton, and should have the various operations repeated as much as possible.
