Abstract

Macromolecular and hydrophilic networks, with the ability to retain solvents within their hydrophilic macromolecular structures, have been utilized for an extended period in as poultice. These networks are mainly cellulose-based pastes, and the most significant issue associated with their use is adhesion and the potential for residues to remain on the surface of artifacts, and its side effects. Over the past decades, and based on new technologies, novel gels with features such as reversibility, complete removability from surfaces, ease of preparation, and the compatibility with solvent-based nanofluids have been introduced to the field of restoration. Among them, modified cellulose gels, reversible organogels and nanomagnetic sponge gels can be mentioned. This article is a review of the introduction of the structure and applications of new gels in the field of cleaning processes within the restoration of historical cultural objects.

Abstract

Red mineral pigments, including minium, vermilion and ocher, have historically been some of the most important and widely used colors ranges in painting, gilding, tabulation and marking verses. This color spectrum in the artworks from previous centuries has shown acceptable stability, with its brightness well-preserved. The preparation of color, as one of the most a significant tools for artists, has long been an important issue, leading to the documentation of  color preparation methods in book design in book design treatises. Minium processing is mentioned as a red pigments in three treatises: Umdeh al-Kottab, Bayan al-Sana, at and Qanun al-Sovar. In the current research the text of these treatises were reviewed, and a comparative study of minium identified in a number of illustrated manuscripts from the Safavid period was carried out using colorimetric method. Initially for this purpose, in the first step, minium was mixed with specific ratios of vermilion to prepare red color tables based on minium. Eight samples of selected miniatures from Safavid period illustrated manuscripts (including 5 illustrated manuscripts from the National Museum of Iran) and 17 prepared color samples were subjected to spectral and color analysis using a spectrophotometer. The color difference values of the prepared samples and the historical samples were then calculated. The results indicate that there is an acceptable color difference between the prepared colors and the historical samples. Therefore, this method can be used in the reconstruction and homogenization of the red spectrum resulting from the minium pigment.

Abstract

Preserving cultural heritage demands a strategic synthesis of scientific, technical, and policy-driven measures to safeguard irreplaceable assets for future generations. Preventive conservation, as a proactive and evidence-based approach, addresses the inevitable material degradation accelerated by environmental and human factors. Beyond regulating environmental conditions, its effectiveness lies in integrating precise documentation, advanced digital modeling and simulation, continuous monitoring, optimized storage and transport, crisis management planning, and legal and insurance frameworks. Sustained success requires interdisciplinary collaboration among specialists in conservation, risk management, heritage law, and education, underpinned by systematic risk identification, assessment, and prioritization. This study critically examines these interlinked dimensions, presenting a holistic framework that enhances resilience, prolongs the lifespan of cultural artifacts, and strengthens the sustainability of cultural heritage. By positioning preventive conservation as both a scientific methodology and a strategic management paradigm, the article underscores its indispensable role in ensuring the enduring survival of humanity’s shared legacy.
