Comparative Laser Cleaning of Graffiti Mural Mock-Ups—Assessment of Contaminant Removal and Pigment Preservation
This study evaluates the effectiveness of laser cleaning techniques for the non-contact removal of unwanted deposits from the surface of contemporary urban mural paintings. Two sets of mock-up samples, painted with popular graffiti spray paints on lime-based plaster, and artificially contaminated, were subjected to various cleaning procedures using Nd:YAG lasers operated in Q-switched (QS), long Q-switched (LQS) or short free-running mode (SFR). …
New Insights into the Materials and Painting Techniques of Ancient Wall Paintings from the Roman Province of Dacia
A group of wall painting fragments discovered at Ulpia Traiana Sarmizegetusa, an important Roman archeological site located in the former Roman province of Dacia (Romania), have been investigated with the aim of defining the material composition of their pictorial layers and exploring the pictorial technology used. In order to preserve the integrity of the murals and minimize sampling, an array of non- and micro-invasive techniques has been emplo…
A Web-Based Platform for 3D Visualization of Multimodal Imaging Data in Cultural Heritage Asset Documentation
Complex demands in the field of cultural heritage preservation often require a multidisciplinary approach and substantial volumes of multimodal data integration and management. The conventional approach to tackling these issues revolves around using different H-BIM (historical building information model) solutions. This paper presents a prototype for a web platform that moves closer to the idea of a digital twin for physical cultural assets. Base…
A Multi-Analytical Study of a 17th-Century Wallachian Icon Depicting the “Mother of God with Child”
As part of a detailed investigation project focused on the painting materials and technical features used in Wallachia during the 17th and 18th century, the imperial icon “Mother of God with Child” from the Orthodox Church of the “Annunciation” in Râmnicu Vâlcea, Romania, was investigated before the restoration intervention. A minimally invasive multi-analytical approach consisting of high-resolution digital radiography, hyperspectral imaging, UV…
Integrated Multi-Analytical Study of the Bronze Vessel From Mălăiești Roman Fort
This paper presents an integrated multi-analytical documentation of a bronze vessel discovered in a 2nd century Roman military fort from ancient Dacia. The process involved 3D digitization, X-ray and hyperspectral imaging, and molecular, elemental, and structural analysis using Fourier Transform infrared spectroscopy, X-ray fluorescence, laser-induced breakdown spectroscopy and X-ray diffraction. The results of the study revealed the composition …
