Ceramic glaze and lead poisoning

Abstract

Since ancient times ceramic commonly used for manufacturing dishes or pots for preparing food. Many people prefer to use ceramic vessels in the cooking process. Because these vessels or pots earn the food especial pleasant flavor.  The surface of these vessels polished until become smooth texture, and sometimes placed inscriptions and decorations on it to give the pots attractive form. Some kinds of paints and pigments contained dangerous chemical compounds like lead , cadmium , ect. Using of these paints or pigments for coating and decoration of these pots may cause liberation of amounts of lead to the acetic acid solution.  Liberation of lead to the food could result poisoning and dangerous deseases to the humen. This is the main reason for this study. The amount of lead released from the ceramic pots to the acid solution obtained from experiment is found to be more than domestic and international standard specification which is not more than 1.00 ppm.
