Micro-fading Workshop

Institute of Sustainable Heritage, University College London  
Jevons Room, First Floor, 14 Upper Woburn Place London WC1H 0NN

Micro-fading is a fast and cost effective accelerated light aging technique 
developed by Paul Whitmore from Carnegie Melon University. It is increasingly 
being used by museums as it is particularly useful for establishing the light 
sensitivity of individual objects where their chemical compositions or fading history 
is not known. Different MFT systems and their applications will be describe. A 
training session and demonstration of the MFT system developed by Jacob 
Llewelyn Thomas will follow. Participants will be invited to bring in their own 
objects to fade as a starting point for discussions on challenges regarding objects 
of different materials with different surface properties. Fading with LED light will be 
demonstrated.

Bodlian Libraries and Hyperspectral Imaging

Weston Library, Bodleian libraries, University of Oxford, Broad Street, Oxford OX1 3BG

The Bodleian Libraries set up Heritage Science just over three years ago in 
acknowledgement of an increasing demand for analysis and other scientific 
support. Of particular interest is Raman spectroscopy which is being 'borrowed' 
from Durham University, and a hyperspectral Imaging system. There is a very 
small laboratory housing this equipment but demonstrations of both will be 
possible to a small audience. There will also be a demonstration of ENVI software 
which is being used to interogate the hyperspectral data for both materail 
identification and revealing hidden texts. The laboratory is within the totally 
upgraded Weston Library (Previously New Bodleian) and a tour of the Exhibition 
spaces, Reading Rooms, centre for Digital Scholarship and public spaces can 
easily be arranged.

Building Conservation Science at Heriot Watt University

Centre of Excellence in Sustainable Building Design, Heriot-Watt University, Edinburgh.

Wed 16 August 2017, 09:30 – 16:00 

The application of heritage science to buildings is the focus of this one day event, hosted at Heriot Watt University, Edinburgh. Speakers from academia and industry will discuss recent research activities that have led to evidence-based conservation of historic building materials such as stone, lime and glass. In addition, attendees will be invited to a tour of the new Lyall Centre to view the petrography laboratory.

Historic document analysis using p-XRF: Pitfalls and Possibilities

The National Archives, Kew, Richmond, Surrey TW9 4DU.  If using Satnav postcode to use is TW9 4AD (Bessant Drive). 

Mon 11 September 2017, 10:00 – 16:30 (Please arrive by 9.45am and wait at reception until collection by an event representative)

Portable X-Ray Fluorescence Spectroscopy (pXRF) has become a widely used analytical tool in Heritage Science and Conservation but the particular challenges and advantages of the technique for analysis of documents and archival collections are not often highlighted. Portable XRF instruments are increasingly available at many libraries, archives, universities and other institutions and conservators or heritage scientists are often asked to employ the technique to answer specific questions. The wide variety of pXRF equipment and software available, together with the complexities of acquiring and interpreting analytical data from historic documents can be challenging to navigate.

This workshop is primarily intended for conservators and heritage scientists who have analysed or will soon analyse historic documents using pXRF. It is held in cooperation with the Icon Book and Paper Group and hosted by The National Archives, Kew and will offer presentations by four guest speakers with experience in pXRF analysis and its application to documents, opportunities for group discussions among participants, and hands-on demonstrations of pXRF analysis.

Speakers will include:

Abigail Bainbridge, West Dean College, Icon Book and Paper Group

Paul Garside, The British Library, Icon Book and Paper Group

Chris Wilkins, Cardiff University, PhD researcher

Helen Wilson, The National Archives, Icon Heritage Science Group

 

18th April 2018

The role of portable X-ray fluorescence (pXRF) in Heritage Science

Glasgow University Archaeology Department, Gregory Building, University of Glasgow, Glasgow G12 8QQ

Wednesday 18th April 2018 14:00 – 17:00

Portable X-ray Fluorescence Spectroscopy (pXRF) has become one of the most widely available analytical techniques at universities, museums and heritage organisations. pXRF has many applications in conservation, archaeology and heritage science but also presents challenges in how best to capture, interpret and present the resulting data.
This event will be presented by Dr. Richard Jones and Dr. Effie Photos-Jones of Glasgow University who will share their expertise in the use of pXRF in the context of Heritage Science on materials such as metals, ceramics, vitreous materials, lithics and paintings. A practical/demonstration session with pXRF equipment as well as opportunities for questions and discussion will be included in the program.

Programme for the day:
1. Placing pXRF as an analytical technique in the context of Heritage Science 
2. Principles of how pXRF works
3. Using pXRF – designing an analysis programme, standards, data capture, interpretation and presentation
4. Applications 1 - metals, ceramics, vitreous materials, lithics 
5. Applications 2 – paintings and cosmetics

 

 

20th April 2018

Introduction to Colour Science and Colour Measurement

Education Room, Charlecote Park, National Trust, Charlecote, Wellesbourne, Warwickshire CV35 9ER

Friday 20th April 2018 10:00 – 16:00

This one day workshop will provide an introduction to colour science and colour measurement for conservators and conservation scientists who need to use colour measurement as part of their conservation practice or research.  Participants will need to have a good general science background, but only a little knowledge of colour science, if any.  The day will include the opportunity to use Konica-Minolta spectrophotometers to undertake colour measurements on a range of materials and surface types.  Course participants may bring their own samples for colour measurement if they wish.

Topics to be covered:

• Introduction to colour science, including light sources and reflection from material surfaces. Operating principles of the spectrophotometer. Practical exercise: Using Konica-Minolta software. Measurement of reflectance spectra of samples.

• Response of human eye to colour. CIE system of colorimetry. Illuminants. Metamerism. Practical exercise: Measurement of tristimulus values of samples (X,Y,Z).

• Colour spaces, CIELAB and colour difference (ΔE). Practical exercise: Measurement of colorimetric values (L,A,B) and calculation of colour difference.

• Factors affecting colour measurement: geometry, gloss and specularity, fluorescence, aperture size, ambient light. Accuracy and repeatability. Practical exercise: measurement with specular included/excluded and UV included/excluded.

• Colour measurement of historic materials and best practice. Issues of dirt, fading, weave, texture, recording. Practical exercise: measurement of woven textiles.

• Advanced colour measurement: recent colour appearance models and colour difference metrics, traceability to national standards, metrics for assessing colour qualities of light sources, including colour temperature and rendering, multispectral cameras. Discussion of participants’ own case studies.

The workshop will be led by Dr Lindsay MacDonald, Honorary Professor at the Faculty of Engineering Sciences, University College London. Dr MacDonald has over 30 years of experience in colour science, and is a co-author of ten books on the subject, including Digital Heritage: Applying Digital Imaging to Cultural Heritage. He is a Fellow of four professional societies, and a former chairman of The Colour Group (GB).

The Heritage Science Group is grateful to the National Trust at Charlecote Park for providing the venue for the training day and to the National Trust and Konica Minolta for provision of spectrophotometers and SpectraMagic software.
