A review of the chrome mordant dyeing of wool with special reference to the afterchrome process

Abstract

The classical age of the Greeks and the Romans saw the introduction of metal salts like ferrous sulphate and alum for use as mordants in the dyeing of fabric. The use of salts of other metals like leads, tin, nickel, zinc, antimony, aluminium and bismuth as mordants, however, only became evident over the last three to four hundred years.
