Dutch An obsolete process for making basic lead carbonate pigment (white lead) by exposing metallic lead to vinegar and carbon dioxide. Reportedly first described by Theophrastos around 300 BC. Also known as the Stack process because the metal ingots were arranged in vertical stacks. See also Thompson-Stewart. [Pg.94]

Thompson-Stewart A process for making basic lead carbonate ( white lead, 2PbC03Pb(0H)2), by reacting lead monoxide ( litharge ) with acetic acid and then with carbon dioxide. Basic lead acetate is an intermediate. See also Dutch, Carter. [Pg.270]

Carter Also known as H.T.S. Carter. A process for making basic lead carbonate pigment (white lead). Lead monoxide, in a slowly revolving drum, is moistened and sprayed with acetic acid. Carbon dioxide is then introduced. Carbonation is subsequently completed in a separate vessel. See also Dutch, Thompson-Stewart. [Pg.60]
