Construction for Preservation of the Fourth Salt Mummy
24 May 2006
(CAIS) -- After completing the urgent activities for the preservation of
the Fourth Natural Mummy of the Zanjan Salt Mine, a research was done for
permanently preserving this unique historical object.
This work was begun by the Research Centre for Conservation of Cultural Relics
and Zanjan's Cultural Heritage and Tourism Organization (ZCHTO). Preparing a
controllable, balanced atmosphere with adequate temperature, humidity and
lighting on the one hand and on the other hand presenting this object for
display, was the goal of the study.
The existence of various materials with different physical and chemical
structures, such as human tissues, clothing made of wool and leather, pottery
and an iron knife; makes this work more complex.
for the pottery which is very durable in most environmental conditions, the
other materials are sensitive and vulnerable to pollutants and fluctuations in
temperature and humidity. Among the more important elements considered was the
expansion and contraction resulting from many and long-term changes in the
immediate environment of the mummy and its belongings which can damage the dry
tissues of the corpse and leather clothing.
Also it opens the way for biological factors to become active. Oxygen and
humidity are import factors for corrosion of iron present in this group, that
is, for the knife. The conclusion of the study and research and investigation of
using an oxygen free environment (anoxy-nitrogen) along with consultation with
experts in conservation, restoration and industrial design resulted in making a
special case for the mummy that would satisfy the requirements.
After transferring this case from the Research Centre to the Cultural Heritage
and Tourism Organization of Zanjan and is installed in the Zanjan Museum, the
Fourth Salt Man of Zanjan will be better preserved and will be ready for
display. Controlling and maintaining an optimum condition (temperature,
lighting, humidity, pollutants, security systems, etc.) in the museum, the
preservation of this relic will be better insured.
