Molar incisor hypomineralization (MIH) affects the permanent incisors and molars, whose undermineralized matrix is evidenced by lesions ranging from white to yellow/brown opacities crumbling enamel incapable of withstanding normal occlusal forces function. Diagnosing condition involves clinical radiographic examination these teeth, with known limitations in determining depth extent defects particular. Optical coherence tomography (OCT) an emerging hard soft tissue imaging technique, which...
This paper summarises the research carried out so far on barniz de Pasto objects from Victoria and Albert Museum (V&A) outlines future areas of development for our collection Indigenous lacquer Latin America. The V&A was first UK public institution to identify decorated with within its collection. Two these were acquired in 2015 2018; others had entered between 1855 1902 but recognised as only after 2018. acquisition a cabinet marked start campaign understand materiality context all...
Collagen is a structural component of the human body, as connective tissue it can become altered result pathophysiological conditions. Although collagen degradation mechanism not fully understood, plays an important role in ageing, disease progression and applications therapeutic laser treatments. To understand alteration, our study photo-disruptive effects were induced I matrix by point-irradiation with femtosecond Ti-sapphire under controlled ablation settings. This was followed...
Research was conducted at the British Museum to investigate potential of Er:YAG lasers address challenging conservation problems where traditional methods had failed. The approach followed perform laser tests on model samples and unregistered objects determine alteration threshold fluence each substrate ability remove contaminants, such as inorganic crusts organic coatings. effects were assessed by means optical microscopy, scanning electron microscopy colour measurements. If successful...
A successful application of Er:YAG laser for the cleaning a restored Assyrian relief sculpture from British Museum collection is presented. Displayed in gallery, has darkened over time due to natural deposition dirt, particular on parts. Since traditional methods have demonstrated be unsuccessful, scientific investigation was performed identify composition soiling and materials used restoration. The analysis suggested presence gypsum, calcium oxalate, carbonates alumino-silicates...
Abstract Metallic inclusions in the paper substrate of historic salted prints are responsible for formation light-colored or white image regions immediately surrounding particle, which especially noticeable areas high density. These low-density “halos” often appear around a dark central spot. Our work shows this is connected with electrochemical reaction metallic inclusion silver salt solution applied during preparation sensitized photographic paper, suggesting that these blemishes found...
Abstract The Victoria and Albert Museum holds an important portrait of the Jamaican scholar writer Francis Williams (c.1692/97–1762), portrayed as a in his study. It is believed to have been painted around 1745 by unknown artist, but circumstances its production are unknown. A technical examination painting was performed using x‐radiography infrared reflectography (IRR), macro x‐ray fluorescence scanning (XRF), digital microscopy, electron microscopy with energy‐dispersive spectroscopy...
