In the Middle Ages only wealthy town people could afford to eat and drink from beautiful, colored glazed cups and plates. But the glazing was made of lead, which found its way into the body if you ate acidic foods. This has been revealed by chemical investigations of skeletons from cemeteries in Denmark and Germany.

Practical, beautiful -- and poisonous

"There really is a big difference in how much lead, the individuals from the cemeteries had in their bodies. This depended on whether they lived in the country or in a town. We see almost no lead in the bones from rural individuals, while the levels of this toxic metal were high in urban individuals," says Rasmussen.

In the Middle Ages wealthy Danes and Germans mainly lived in towns, while the rural population was generally poorer and more isolated. The wealthy could afford to eat and drink of glazed pottery, and this was the main source of lead poisoning.

"In those days lead oxide was used to glaze pottery. It was practical to clean the plates and looked beautiful, so it was understandably in high demand. But when they kept salty and acidic foods in glazed pots, the surface of the glaze would dissolve and the lead would leak into the food," says Rasmussen.
