A French treatise of 1798 on dyeing cotton and linen threads and fabrics, preceded by a theory of colour fastness and followed by guides to cultivating woad, weld and madder. It covers fibre examination, bleaching, mordants and colouring substances (cochineal, madder, indigo, woad, weld, galls). It gives dye procedures by colour, including Adrianople (Turkey) red, yellow, green, violet, black, grey, olive and brown. Further sections treat silk handkerchiefs, resist-dyed blue and white cloth, Saxon blue, and dyeing cotton velvet.
