The famous blue and gold braided beard, burial mask of Tutankhamun was damaged when the relic was being cleaned in the Egyptian museum where it lays. The bearded was knocked by a conservationist.
The mask among a few other contents is the top exhibit of the museum. It is a highly visited tourist site but not completely kept in full maintenance. Relic as important as the 3,300 year old Tutankhamun mask should be kept in great care feet expert conservationists.
The conservators from the museum have varied opinions on what actually happened with beard. They say that the mask was knocked off by accident while the mask’s case was being cleaned or removed when it was loose.
The beard was fixed quickly with inappropriate adhesive and irreversible material, epoxy which has a high property for attaching and is generally used on metal, stone but was in every way inappropriate for Tutankhamen’s golden mask.
