Archaeological excavations at the ancient site of Haft-Tepe commenced in the winter of 1965 under the direction of Dr. Negahban and continued for fourteen seasons until 1978. These excavations led to the discovery of a significant assemblage of architectural remains and diverse historical artefacts. Among the finds were various ceramic vessels and objects, a collection of clay tablets, seals and seal impressions, a range of bronze artefacts, numerous fragments of painted mud plaster, coffins, stone objects, clay busts, as well as decorative items such as necklaces, plaques, glass vessels, and bone tools. A considerable portion of these artefacts is today preserved in the Haft-Tepe Museum. In response to the quantity and importance of the discoveries, the idea of establishing a museum adjacent to the archaeological site was raised during the second season of excavations. Construction began in 1970 and, upon completion, the museum was inaugurated in the spring of 1973. With the outbreak of the Iran–Iraq War in 1980, the museum was closed; part of its prominent collection was transferred to Tehran, while other objects remained in situ. In the spring of 2001, research and conservation activities were resumed under the auspices of the Chogha Zanbil - Haft Tepe Cultural Heritage Base. One of the first major undertakings during this period was the reorganisation of the museum’s collection, carried out in collaboration with graduate students of conservation from the University of Art, Esfahan. In this process, artefacts that had previously been kept in unsuitable and scattered conditions were collected, classified, recorded, documented, and systematically arranged. This initiative laid a crucial foundation for the long-term preservation and safeguarding of the invaluable heritage of Haft-Tepe.

Soluble salts are known as serious threat for monuments and historical porous materials. The alteration mechanism related by soluble salts such as rocks is essentially a physical process based on the stress level generated by the crystallization of the salts in the pores. In recent years many ways have been developed to extract or deactivate these salts. The efficiency of every desalination system is being evaluated by the amount of extracted soluble salts and the depth of treatment in material. In fact, ionic transport is result of a consortium of energies: kinetic energy, electric energy and chemical energy. These three energies are united together to move and extraction of soluble salts in an optimum  desalination system. The electro kinetic technique is a non-destructive method to extract soluble salts based on electric migration of ions inside the material. This method is even applicable for matrixes with very fine porosity and very low hydraulic permeability. In recent years this method
has been specially considered in European countries. High amount of extracted salts and deep effect on materials have been caused to happen many researches on this topic on historical heritage and considerable results have been gained. This article is a review of background, principles and generals of this method in conservation and desalination of historical porous materials which are threatened by soluble salts alteration. Results from traditional desalination ways are compared with this method as a pioneer technique show an improvement of the quality of desalination, saving time and high efficiency of this method.
