Note 359 — MINERAL POISONS. (continued 3)
Reading edition
The art of glazing earthenware with lead is of modern invention; that part of the old earthenware, preserved in the British museum, which is supposed to have been of Roman manufacture, is not glazed. The vessels, which are called Etruscan, and which are supposed to be of greater antiquity than the Roman, have indeed a paint or polish on their surfaces; but that does not appear to resemble our modern saturnine vitrification.
