It can cause considerable damage, leading to the loss of lives and possessions. Concerning fire safety recommendations, buildings must be protected by an integrated system of passive and active measures. Two passive measures widely used in many industries are fire-retardant and fire-resistant coatings. These systems provide a fire-protective layer to the surfaces of flammable and non-flammable materials, delaying or preventing their ignition, reducing the heat transfer from the source to the substrate and decreasing the flame spread and the release of smoke and toxic gases. When exposed to fire, according to the different mechanisms of action, fire-protective coatings (FPC) can be classified as non-intumescent and intumescent. Despite being widely mentioned in heritage fire safety guidelines, studies on their application in the field are still scarce. Namely, research on the safety and efficacy of their application near collections (in support materials) and systematic studies comparing different formulations. Therefore, this research assembles interdisciplinary studies on the use of FPC to deepen knowledge and theoretically identify the feasibility of their application in collection support/storage materials or exhibition furniture (bookshelves, cabinets, plinths) in heritage environments.</p></div>","PeriodicalId":15480,"journal":{"name":"Journal of Cultural Heritage","volume":"68 ","pages":"Pages 316-327"},"PeriodicalIF":3.5,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1296207424001389/pdfft?md5=a75e85e09c89a1d229da79302fa68842&pid=1-s2.0-S1296207424001389-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141605472","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A selection of triterpenoid, poly(cyclohexanone), poly(cyclohexanol) and poly(isobutyl methacrylate) resins was chosen to make dammar, Ketone Resin N, MS2A and Paraloid B67 varnishes. Before creating varnish films, thermogravimetric analysis (TGA) was performed to determine the thermal stability of the resins as received from the manufacturer. The resins were measured at six different heating rates, and the kinetic activation energies (<em>E_a</em>) were calculated using the Flynn-Wall-Ozawa method. Also, differential scanning calorimetry (DSC) was performed to determine the resins' glass transition temperatures (<em>Tg</em>). After a 170.6 klux·h dose of radiation (λ&gt;310 nm) simulating daylight through window glass of approximately 53 museum years, the varnish films were irradiated with an Er:YAG laser. The laser was used in the Very Short Pulse (VSP ≃ 100 µs) and Short Pulse (SP ≃ 300 µs) modes. The 2940 nm laser beam with a 4 mm diameter was fired onto dry and prewetted varnishes using a working distance of 20 cm. Single laser pulses with fluences ranging between 0.5 and 2.7 J/cm² were used. A prewetting solution of 1 % v/v Tween®20 surfactant in deionised water was applied to the varnish films. Er:YAG transmission through the aged varnishes was monitored in real time and showed that the transmitted energy increased almost linearly with fluence, except for the Paraloid B67 films which did not interact with the laser. Chemical changes were monitored using Attenuated Total Reflectance/Fourier Transform Infrared (ATR/FT-IR) spectroscopy. A reduction in hydroxy groups and carbon-hydrogen bonding was observed as a function of fluence for dammar and Ketone N films, while no change was observed for the dry and prewetted MS2A films. FTIR was also employed to experimentally determine the absorption coefficient of the varnish films. Optical Microscopy and low-vacuum Scanning Electron Microscopy (SEM) in the Backscattered Electron (BSE) mode were used to compare the dry and prewet irradiated spot areas.

This study investigated the deterioration of copper objects by analysing the black spots that appeared on them and proposes environmental conditions to suppress the appearance of black spots. Bronze artefacts excavated from a marine archaeological site, on which black spots were generated, were closely observed, and investigated. First, X-ray fluorescence and micro-X-ray diffraction analyses were performed on a bronze artefact, from which the black spots were removed, to determine the composition of the artefact. Second, to investigate the composition of the black spots, fine structure analysis of the black spots on the fine fragments of the bronze artefacts was conducted using scanning and transmission electron microscopy, energy dispersive X-ray spectroscopy, and electron diffraction (ED) analysis. The results indicate that the black spots were partially composed of metallic copper and a fine particle mixture of Cu₂S and CuSO₄. These results imply that the transformation of copper sulfide to metallic copper may have played an important role in the initiation and propagation of black spots. In this study, ED analysis was performed on the microscopic area of the black spots; no amorphous phases were detected, and all observed phases were identified as crystalline materials. To determine the sources of gas-phase sulfur compounds that cause black spots, H₂S and carbonyl sulfide (COS) emissions from a spherical clay artefact (a cannon ball with gunpowder excavated from an underwater archaeological site) which was exhibited in the same showcase with the bronze artefacts were analysed via gas chromatography. The concentrations of H₂S and COS were 0.462 and 8.636 ppb, respectively; these are significantly higher than those in the lower troposphere. These results indicate that deterioration by black spots occurred because of H₂S and COS, which were emitted from the spherical clay artefact excavated from an underwater archaeological site in the exhibition case.

Historically, efforts to preserve watercolor pieces in museums, institutions, and private collections have relied on intricate and expensive techniques. Unfortunately, these methods are not practical for the broader community of artists and less affluent collectors. Furthermore, the introduction of foreign preservation materials, which can interact with the artwork's components, poses a risk to the original visual appeal. Consequently, watercolor art collections have lost some of their appeal compared to oil paintings on canvases. This study endeavors to offer an alternative, straightforward, and cost-efficient approach to safeguarding watercolor artworks created on high-quality watercolor paper, a type commonly used by typical watercolorists, making it a suitable candidate for this investigation. This approach also avoids introducing additional substances to the artwork. The protective technique involves the application of commercially available acrylic gesso to a fresh sheet of watercolor paper. This gesso-coated paper serves as a backing for framing and displaying the original watercolor artwork, without the need for any foreign preservation materials to be added to the artwork itself. To assess the effectiveness of this protection method, a comparison was made between the foxing tendencies of protected and unprotected paper artworks stored for a decade. These samples were subjected to various analytical techniques, including optical microscopy (OM), confocal laser scanning microscopy (CLSM), field emission scanning electron microscopy with energy dispersive X-ray spectroscopy (FESEM-EDX), X-ray diffraction (XRD), attenuated total reflectance-Fourier transform infrared spectroscopy (ATR-FTIR), and thermogravimetric analysis (TGA). The results revealed that, when compared to untreated samples, rarely any foxing spots were observed on any of the treated samples, and both the oxidation and degradation of cellulose fibers were diminished. Additionally, the analysis showed that the acrylic gesso comprised inorganic components such as calcium carbonate (CaCO&lt;sub&gt;3&lt;/sub&gt;), dolomite (CaMg(CO&lt;sub&gt;3&lt;/sub&gt;)&lt;sub&gt;2&lt;/sub&gt;), rutile (TiO&lt;sub&gt;2&lt;/sub&gt;), and organic acrylics. The carbonates created a mildly alkaline environment, neutralizing the acidity in the paper. The titanium dioxides exhibited biocidal and fungicidal properties due to their photocatalytic characteristics. The acrylic component bound and dispersed the inorganic constituents, and the coating formed a less impenetrable barrier layer as indicated by the scanning electron microscopy (SEM) results.
