Once these items are uncovered, they become extremely vulnerable. The choice of the materials one uses for repair is very important. We reuse ancient building material and try to match the ancient mortar in color and consistency. Stone masons strengthen walls and reinforce rock and brick work with a special concrete mix. Mudbrick is coated and chemically treated when deemed necessary.
Archaeologists also have to be concerned about the protection of their discoveries.
The main threats are water, wind, light, insects, rodents and theft. The artifacts have to be stored in vaults called magazines or store rooms. Each year our objects are placed in custom-made boxes designed to protect the items. The boxes are made out of a specially treated wood, treated to minimize fluctuations in moisture. They are also treated with an insecticide.
