Meaning

A historical lead preparation divided into medicinal and alchemical forms by the author. The alchemical form is assigned purification and whitening uses, while the medicinal designation reports a period judgment rather than present-day safety. Ceruse also serves as a procedural comparison when surface material is removed from other metal plates. Its recurring name links products without making their preparations identical.
