In investigation of production technology and provenance studies of historical objects as well as to propose and develop strategies for restoring and conservation, it is necessary to get information about studied samples. This information is different according to the type and kind of materials of historical objects.
Today, identify and accurately determine the elemental composition and constituent material of given sample is one of this essential information that be able to measure using modern laboratory instruments In this paper, was presented some results was obtained in past few years from different historical and cultural objects using micro ion beam analysis in Van de Graaff laboratory of Nuclear Science and Technology Research Institute.
Investigation of Painted enameled potteries to determine the different pigments used in, determine the thickness and purity of the gold layer in gilded enameled potteries, determine the responsible elements to brightness of wall painting in a historical place, Investigate the causes of corrosion and degradation of an old manuscript, determine purity of Elymais bronze coins and determine the type of Iranian historical and ancient glasses are some studied objects that will be presented in this paper.
The results of these analysis will significantly help to investigate the production technology, to determine the authenticity of the samples and finally to use in restoration of these historical objects.
Preserving intangible cultural heritage in historic urban spaces requires a nuanced understanding of culture, practices, and meanings, as well as active community engagement. This study examines the impact of designing cultural narratives on public participation in safeguarding intangible heritage within the buffer zone of the Tabriz Historic Bazaar Complex (Pasazh Alley). Using an integrated mixed-methods design, ethnographic self-documentation, field observation, and semi-structured interviews with residents and shopkeepers produced lived-experience data coded into 28 core items. A questionnaire based on these items was distributed to 50 users and 16 experts. Analyses included exploratory factor analysis, reliability testing, Pearson correlation, and multiple regression. Results show significant relationships between cultural components (material, behavioral, spiritual) and place attachment. Designed cultural narratives were evaluated and ranked using the TOPSIS multi-criteria decision method. Findings suggest narrative design grounded in stakeholders’ lived experience functions as a practical tool to convey intangible values, strengthen place attachment, and promote active community participation in heritage protection.
