Chromate of lead, as a pigment has been for some time in use; M. Lassaigne, in 1820, made public a process for dyeing cloth with this article, which has since become pretty common in this country.

Immerse hanks of scoured silk for a quarter of an hour in a weak solution of acetate of lead at the ordinary temperature; take them out and wash them in a great deal of water: then dip them into a weak solution of chromate of potash. They immediately take a fine yellow colour; at the end of ten minutes the effect is complete. From this colour being decomposed in part by soap and water, it is chiefly applicable to silks. But by applying, however, a mordant of acetate or nitrate of lead, and passing the goods through bichromate of potash, a very beautiful and sufficiently fast yellow is now given to cotton goods in this country.
