Red Pigments:—
Chrome Red is a bichromate of lead.
Red Lead or Minium is the red oxide of lead.

The Nitrate of Lead, much used in calico-printing.
The Pyrolignite of Lead, which is an impure acetate used in dyeing; and
The Sulphate of Lead is a by-product in the preparation of acetate of aluminium for dyeing.
The alloys containing lead are extremely numerous; but, according to the experiments of Knapp,[822] the small quantity of lead in those used for household purposes has no hygienic importance.
