Artificial LACCA, or Lacque, is also a name given to a coloured substance drawn from several flowers; as the yellow from the flower of the juniper, the red from the poppy, and the blue from the iris or violet. The tinctures of these flowers are extracted by digesting them several times in aqua vite, or by boiling them over a stove fire in a lixivium of pot ashes and alum.
An artificial lacca is also made of Brasil wood, boiled in a lixivium of the branches of the vine, adding a little cochineal, turmeric, calcined alum, and arsenic, incorporated with the bones of the cuttle fish pulverized and made up into little cakes and dried. If it be to be very red, they add the juice of lemon to it; to make it brown, they add oil of tartar. Dove-coloured or columbine lacca is made with Brasil of Fernambuc, steeped in distilled vinegar for the space of a month, and mixed with alum incorporated in
cuttle fish bone. For other processes, see COLOUR-MAKING.
