Lead-glazed pottery is widely used in this country, and is responsible for numerous lead poisonings both among peasants and town people. In a series of cases the analysis', of the content of lead-glazed pottery and the test of extraction with acetic acid were carried out. The results are discussed as regards the factors influencing lead extraction. Special attention is paid to the influence of temperature, pH, and the effect of various organic and inorganic acids. It is pointed out that lead-glazed pottery should not be used for storing any food or drink containing organic acids, nor should such a content be warmed up or boiled.
