In 1949, archaeologist Boris Piotrovsky discovered 97 bronze bowls on the Karmir-Blur hill in Armenia. They bear almost no traces of corrosion. Which makes them very special - because they have been buried for 2,700 years. In this white paper, read about the unusual case of the corrosion-resistance bronze bowls of Urartu.
The bowls are currently on display in the State Hermitage Museum collection, where the possible causes for non-corrosion have been researched. Environmental conditions excluded any inhibitors, electrochemical corrosion protection or other external causes. The measurements of the composition of the bronze eliminated any additives to the alloy.
By using light and electron microsocopy, the surface of the bowls have been investigated to unveil their secret and to explain their significance to the museum's visitors.
