Exposure to an atmosphere rich in volatile pollutants can endanger collections in museums, galleries, libraries or archives. Monitoring volatile pollutants in museum microclimates remains an unusual practice in most institutions. Volatile organic compounds (VOCs) can be released by many sources, including the artefacts’ materials themselves. The presence of pollutants in an enclosed space with poor ventilation, adding to high temperature and relative humidity levels or significant fluctuations, may increase the risk of damage for the more susceptible materials. The tendency observed in museums to enclose artefacts in vitrines or boxes may contribute to the formation of microclimates with high VOCs concentration. Based on the studies developed in the last decades, this work intends to draw attention to the risks associated with gaseous pollutants in museum environment and outline some recommendations that encourage cultural heritage institutions to implement a pollutant monitoring plan associated with risk prevention.

In the art market, it is a real possibility that the conduct to be adopted in the preservation of contemporary art cannot be put into practice without secession with the conservation and restoration guidelines. The aim of this study is to analyse if the most prominent professional guidelines fit into the market framework, or if it is possible to find divergences or reasons to lay aside in commercial practice. The work compared the fundamental guidelines with the practical objectives of the art market, qualitatively analyzing the results with the personal testimony collected from the agents of the national market on the issue raised. From this analysis, it was possible to identify the need for diagnostic models balanced with the safeguard of the commercial circumstance of the assets, seeking to develop a line of diagnostic guidelines that offer analytical usefulness to the conservator, in actions in the context of the contemporary art market in Portugal.

The festive culture encompasses different representations that enrich the collective imagination as elements of heritage identity reinforcement. Giants and big heads are a statement of such folkloric richness, symbolically linked to the tradition of immaterial connotation. This article contextualizes, historically and ichnographically, one of the papier mâche giants from the Corpus Christi festival in the Valencian city of Xativa. The technical, material and physiognomic examination of the sculpture, popularly known as “La Turca”, served as a preliminary study to determine its state of conservation. As a festive element used in processions, this sculpture exhibited significant structural and dimensional problems, as well as previous intrusive interventions, especially in polychrome areas, repeatedly applied with the purpose to recover the work’s appearance. Finally, based on the preliminary examinations, curative conservation and restoration treatments were performed, aimed at the most relevant deteriorations.

Conservation and restoration on archaeological objects in glass often involve the removal of materials from previous restorations and comprise a deep knowledge about present and past methodologies. This article presents a literature survey and critical analysis of the main materials used in the different stages of intervention: cleaning, consolidation, joining fragments and filling gaps. A considerable number of used products was identified, which illustrates the use of various methodologies among professionals from this area. Cleaning methods vary from mechanical methods using a brush (less invasive) to the use of various acidic solutions, some of which can endanger the integrity of objects, being the most common ethylenediamine tetra-acetic acid. We highlight the use of epoxy resins as adhesive, consolidant and filler, as well as the acrylic resin Paraloid B-72, identified as reversible, colorless, stable and inert. This survey and analysis of the bibliography reveals the need to implement common intervention methodologies dedicated to this material.

Consolidation is a treatment of great importance for archaeological wall paintings due to their state of preservation, in which the lack of cohesion of the mortar and the pulverulence of the pictorial layer are common. The objective of this work has been to evaluate consolidation tests that have been carried out on decontextualized fragments belonging to five different wall paintings (from different periods and with differences in their state of conservation and in their painting techniques). For this, two of the most used treatments in consolidation of archaeological coatings, such as an acrylic resin and ethyl silicate, have been compared with two treatments that use nanoparticles, such as nanolimes and nano ethyl silicate, together with a bioconsolidation treatment used until present mainly for the consolidation of stone material: bacterial carbonatogenesis.

The global COVID-19 pandemic has forced the closure of various sectors of activity, including universities, laboratories and businesses, impelling researchers and technicians to temporarily halt their research or, at their best, to develop it in a limited way.

This article intends to define and make available guidelines for the preventive conservation of hand-painted glass slides for magic lanterns, the first optical instruments for the projection of images, invented in the 17th century. For this purpose, around 300 hand-painted glass slides from the Portuguese Cinematheque – Museum of Cinema (CP) and Nacional Museum of Natural History and Science of the University of Lisbon (MUHNAC), were studied in terms of representativity in these collections, discursive genre, type of construction or movement mechanism, state of preservation and degradation problems. A survey was designed and distributed to institutions across the globe aiming for an overview of the formal characteristics of the collections of magic lantern slides and the preventive and interventive conservation measures undertaken. The guidelines are focused on the environmental conditions (temperature, relative humidity, and light), fine particles and pest control, storage and display conditions and materials, as well as handling. Recommendations on performative projections or demonstrations are also provided.

This paper proposes a reflection on the evolution of the concept of preventive conservation in archaeology and its social interaction (or socialization), from a reflexive and theoretical point of view. It is a manuscript that outlines the current role of Preventive Conservation Plans and how the participation of society in heritage management is addressed. Heritage is understood as a multi-temporal entity that transcends the materiality of the object and enables us to turn towards a preventive archaeological conservation that preserves current contexts and their stories, integrated into participatory or community archaeology. Through a series of questions, the reader will become an active player in questioning who conservation actions are targeted at, whether society or experts. Lastly, it will outline some proposals for promoting a preventive conservation that tackles, transforms and broadens its desired social dimension.
