Pour into the alkaline liquor which holds in solution the colouring
part of bastard saffron, such a quantity of lemon juice as may be
necessary to saturate the whole alkaline salts. At the time of the
precipitation, the latter appears under the form of a fecula full of
threads, which soon falls to the bottom of the vessel. Mix this part
with white talc, reduced to fine powder, and moistened with a little
lemon-juice and water. Then form the whole into a paste, and having
put it in small pots, expose it to dry. This colour is reserved
for the use of the toilette; but it has not the durability of that
prepared from cochineal.
