Mummies, dead

Many museum objects are damaged by insects and microorganisms. It is often difficult to combine the conservation of ancient objects and their exposure to the public.
Recently a technique has been launched to combine both aspects. The aim is to avoid the biological disaster of ancient objects and at the same time properly organize the exhibition. The mummy of the images was placed in a box of airtight transparent material and the air was replaced by low damp nitrogen. The combination of low humidity (35-40%) and low oxygen concentration (2%) allowed very low biological activity (95% lower).
Nitrogen versus fumigation systems used so far is cheaper, safer and more useful.
