Studies on lead extraction from glazed pottery under different conditions
- 69 Downloads
An investigation was carried out to estimate the amount of lead extracted by storing acetic acid in 231 pieces of glazed earthenware pottery. The average concentration of lead was found to be 4.2 mg/litre and the range was 1.0 to 6.5 mg/litre. The amount of lead extracted increased sharply between 70° to 90°C. Hence storage of hot beverages in pottery for long periods may pose health hazards due to chronic lead toxicity.
