DUTCH PROCESS

The Dutch process (or stack process) was formerly the principal method by which white lead was prepared. It consisted building a stack of earthenware pots containing acetic acid upon a thick layer of spent tan or manure and placing strips or coils of metallic lead over the pots; boards were then laid to forma false floor over the whole and more stacks built on top. The entire structure was then sealed and over time the metallic lead converted into lead carbonate by corrosion caused by the action of the acetic acid vapour in the presence of carbon dioxide.
