The Embassy of Poland in Cairo has posted on its official FB page some of results of the Polish-Egyptian Archaeological and Conservation Mission working on the Temple of Hatshepsut at Deir al-Bahari, Luxor, as documentation for these works.
On the scope of the work, the embassy page says:
All the original blocks underwent full conservation treatment before montage, this means conservation of the paint, plaster and the stone itself. Preliminary conservation treatment consisted of reinforcing the paint layers, and consolidating the pigments, ancient plasters and mortars. The layer of polychrome protected in this way underwent cleaning from thick layers of soot and dirt. The reliefs in the Sanctuary recovered their original intensive colours as a result of this treatment; it is visible in the representation of Tuthmosis III depicted in the west wall tympanum of the Bark Hall.
The posted picture shows a wall relief before and after conservation.
