“…The MFT technique can help us to extrapolate changes in color over time. Moreover, MFT is a technique that provides not only information about the current state of the material, but also gives information about the potential color changes that the material may experience because of uncontrolled and long light exposure . Whitmore et al developed the MFT technique in the late 1990s.…”

The documentation of archeological sites requires the adoption of non‐destructive techniques to safeguard the unique legacy coming from prehistoric periods. This article tackles the assessment of lightfastness properties on a rock art site to determine the behavior of motif's color deterioration over time in Remígia Cave, Castellón (Spain), which is considered part of a UNESCO World Heritage Site. The measurements were performed using a microfade testing device to analyze the spectral characteristics and the aging properties of the colorant system and various substrates on site. Two scenarios have been identified depending on whether the lightness (L*) parameter of the rocky substrate changes or not in relation with the painted motifs. If the substrate remains stable without any change, red motifs containing iron oxide pigments will become more visible. If the substrate becomes lighter, the pigments will experience similar changes. Therefore, the contrast between paintings and support will be considerably enhanced.

“…In addition, the responsiveness of objects to visible light irradiation was studied using MFT. The MFT device used in this study was constructed by researchers at the National Museum in Krakow and at the Faculty of Chemistry of the Jagiellonian University, and it is based on the original prototype designed by Whitmore et al This instrument consists of a high‐power light source, a 0°/45°geometry optical setup, and a VIS reflectance spectrometer. The high‐power light source employed is a HPLS 30‐04 solid state plasma light source (LIFI) from Thorlabs (New Jersey, USA).…”

The chemical identification of materials is the first step for developing and implementing recommendations for the care and display of resin cast and plastic objects in museum collections. This paper presents advantages as well as limitations of portable Raman. Therefore, a comparative analysis of portable and benchtop Raman instruments was performed in the study of materials found in the contemporary art collections of the National Museum in Krakow.The results of the Raman study were complemented with those obtained using Fourier transform infrared, near infra-red, and gas chromatography mass spectrometry, in order to verify their accuracy. The results of this study showed that portable Raman spectroscopy is a suitable technique for the identification plastics in museum collections.

“…To this end, a customised set‐up was devised and developed for conducting in situ MFT through the framing glass. MFT has been widely accepted by the conservation science community and is being currently used in numerous cultural institutions around the world since it is a safe and reliable tool for determining an object's response to light in the context of exhibition lighting . The information gathered as part of the current study will serve to expand the current knowledge on the photosensitivity of early nineteenth century pastel artworks produced in Europe in the context of lighting management solutions for their permanent exhibition.…”

Paper‐based heritage objects on exhibition are typically framed using a transparent glazing material such as glass or acrylic. This often makes the task of measuring their light fastness a difficult one since cultural institutions may have unframing restrictions, especially for large‐format objects. However, a testing programme recently conducted at the National Museum in Krakow has revealed that in certain cases it is possible to obtain colorant stability information directly from a framed object. Microfading testing results are reliable if the distance from the object to the protective glazing is adequate to allow proper illumination and collection of reflected light. This paper presents a case study of six large‐format pastels on paper by Stanisław Wyspiański, one of the most outstanding and versatile artists at the turn of the twentieth century in Poland. Some of the orange and pink areas showed higher sensitivity to light with fading rates that remain within the Blue Wool 1–2 range. The objects have been classified according to the light sensibility of their colorants, and this information has allowed development and implementation of exhibition guidelines that serve to minimise the degradation associated with museum illumination. In addition, scientific imaging, microfading data and computer analysis of the images have allowed virtual representation of the potential colour changes that these artworks may experience as a result of uncontrolled and long exposure to gallery illumination.
