Manufacturing variations in ISO Blue Wool fading standards under microfading exposure conditions
As is the case for other accelerated light-ageing methods, microfade test results are usually rated against the responses of the International Standards Organisation’s Blue Wool Fading Standards, the production of which is regulated by the International Standards Organisation. The suitability and convenience of the ISO Blue Wools for this purpose...Ford, Bruce ; Korenberg, Capucine

Successes and challenges in laser cleaning metal artefacts: A review
Over the past fifty years, laser cleaning has progressively become an established conservation cleaning treatment for a range of artefacts, including stone, ceramics and paintings. While its application to metal is not widespread, there have been several reports of laser cleaning on metal artefacts. However, the findings of these studies...Bertasa, Moira ; Korenberg, Capucine

A non-invasive investigation of Egyptian faience using Long Wavelength Optical Coherence Tomography (OCT) at 2 μm
Egyptian faience is a non-clay ceramic semi-transparent material formed of a quartz core and alkali-lime glaze. Previous investigations have identified production techniques by using microstructure images obtained from invasive methods. Optical coherence tomography (OCT) is a non-invasive 3D imaging technique that produces virtual cross-sections of transparent and semi-transparent materials. A...Read, Margaret ; Cheung, C.

Investigating the potential of the Nd:YAG and Er:YAG lasers for the cleaning of feathers: a pilot study
A dual-wavelength Q-switched Nd:YAG laser emitting at 1064 nm and 532 nm and an Er:YAG laser were tested on a range of feathers containing melanin, carotenoids and psittacofulvins. Dyed, white and iridescent feathers, as well as down feathers, were also included in the study. First, the damage threshold fluence was...Bertasa, Moira ; Korenberg, Capucine

Establishing the production chronology of the iconic Japanese woodblock print ‘Red Fuji’
First printed in 1831, ‘Red Fuji’ by Hokusai is one the most iconic Japanese woodblock prints and thousands of impressions were printed from its original set of woodblocks, often in different colour schemes and using different printing effects for different editions. The aim of our research was to systematically study...Korenberg, Capucine ; Derrick, Michele ; Pereira-Pardo, Lucía ; Matsuba, Ryoko

Tackling conservation challenges using erbium lasers: case studies at the British Museum
Research was conducted at the British Museum to investigate the potential of Er:YAG lasers to address challenging conservation problems where traditional conservation methods had failed. The approach followed was to perform laser tests on model samples and unregistered objects to determine the laser alteration threshold fluence on each substrate and...Pereira-Pardo, Lucía ; Melita, Lucia N. ; Korenberg, Capucine

Investigating the Potential of the Er:YAG Laser for the Removal of Cemented Dust from Limestone and Painted Plaster
A successful application of Er:YAG laser for the cleaning of a restored Assyrian relief sculpture from the British Museum collection is presented. Displayed in the gallery, the sculpture has darkened over time due to the natural deposition of dirt, in particular on restored parts. Since traditional cleaning methods have demonstrated...Melita, Lucia Noor ; Węgłowska, Katarzyna ; Tamburini, Diego ; Korenberg, Capucine

Emissions from MDF: governing factors and mitigation strategies
Many museums use elements, such as baseboards and inserts, made of medium density fibreboard (MDF) inside showcases. MDF is manufactured by bonding wood fibres with a resin. It emits volatile compounds that can be harmful to a wide range of museum objects, including formaldehyde. There is currently no entirely effective...Korenberg, Capucine ; Bertolotti, Giulia

The use of erbium lasers for the conservation of cultural heritage. A review
The characteristics of erbium lasers (Er:YAG) make them a promising tool for the conservation of cultural heritage, and yet they still remain less widespread than other lasers in this field. This review aims to summarise, compare and evaluate the results of case studies and experiments published so far about Er:YAG...Pereira-Pardo, Lucía ; Korenberg, Capucine
