The present study focused on the chemical composition of archaeological Cartonnage fragmentcartonnage fragments which hadwere discovered in Lisht and preserved in a Dahshour storeroom, in addition to determinedetermining the damage caused as a result of burying the object having been buried in sandy soil. The examination results revealed the use of linen as a textile layer, calcium carbonate (calcite) as a ground layer, Egyptian blue, Egyptian green, and red ocher as pigment layer and gum Arabic as organic media. These materials suffered from many damage factors, especially the effect of high temperature which changed the expansion and shrinkage rates and causedcausing cracks, missing parts, general weaknessesweakness of all layerlayers, shrinkage and wrinkle ofwrinkles in the textile layer. The microbiological damage also had effected, his effect appeared in the form of staining onof the textile and pigment layer surfaces, and weakness of the pigment layers due to loss of the media function.

The painted funerary Cartonnage,cartonnage was a type of archaeological material used in ancient Egypt since the first intermediate period to late period (Hassaan, 2016; Afifi, 2011). theseThese masks generally consist of Compositecomposite layers arranged from top to bottom, with pigment layerlayers which were sometimes gilded, the ground layer (gesso) and the support layer (Scott, 2003). theThe layers were usually mixed with a binding media such as gum Arabic (AL-Emam et al., 2015) or Animalanimal glue (Ali, 2016; Afifi, 2011; Scott et al., 2008; Borg, 2010). ItThese were mostly buried with their mummies in a graveyard or directly in the soil like the study object which was discovered in lishtLisht's sandy soil.
