New dating for some of Canterbury Cathedral's glass
Readers of Vidimus will no doubt be aware of the recent exciting news that glass panels from the “Ancestors Series” at Canterbury Cathedral may be the oldest existing stained glass windows in England. This series was created and installed in the Cathedral, beginning in the late 1170s (after a fire in 1174) and continuing through to 1220. It has recently been discovered that a panel from this series is much older than originally thought, dating back to the period 1130-1160. This discovery was made by a team of scientists from UCL and conservators from Canterbury Cathedral using a technique known as portable x-ray fluorescence (pXRF), with an approach developed for the purpose by Dr Laura Ware Adlington, who was then a PhD student at the UCL Institute of Archaeology. Their results confirm research carried out in the 1980’s by the art-historian Professor Madeline Caviness who suggested that four of the panels installed in the 13th century were stylistically much older. Full details of the press release issued by UCL can be accessed here and the detailed report on the work may be freely downloaded from the journal Heritage.
Readers may be interested to know how pXRF can help date glass. It is a method of analysis which determines the chemical elements and their concentrations in a material. Medieval glass was composed of two main ingredients, a flux (typically the ash of inland trees or bracken) and silica, usually in the form of sand. The compositions of ash and sand vary depending on where the glass was made, and the proportions used in glass making changed over time and differed between workshops. This opens up the possibility of dating or sourcing glass from its chemical composition. While a chronology of glass chemical compositions has been established for the post-medieval period in England (see works by Dr David Dungworth), similar work is still on-going for medieval glass.
It is not straightforward, however. Handheld pXRF works by directing a beam of x-rays at the glass of interest. The x-rays interact with the glass surface and send out a spectrum of new fluorescent x-rays which are diagnostic of the elemental make-up of the glass. Because pXRF is non-destructive and portable, it is well suited for windows but they present a number of difficulties: the presence of weathering or dirt on the glass surface, the difficulties in positioning the instrument against the glass surface because of the protruding lead cames, and the fact that air absorbs the X-rays of light materials.
The authors overcame these issues by devising a special 3D-printed nose which allowed the positioning of the pXRF instrument between the cames and by concentrating on a few diagnostic elements which were characteristic of the sand and the flux, which can travel through air and which were generated below the surface of the glass, minimising the problems due to weathering. This approach allows the identification of glass groups that are related to different recipes, sources, and/or date. The authors were therefore able to analyse and compare panels from different stages of the Canterbury construction programme and concluded that the Nathan panel, which was installed in the early thirteenth century, has a chemical composition resembling the earlier panels, and is therefore consistent with Caviness’s interpretation.
With scaffolding and a suitable attachment, a pXRF instrument, which in looks and weight is rather like a hand-held electric drill (without the drill bit), can be held against a stained glass window. With appropriate protection for the operator, a number of readings can be safely taken from all parts of the window and compared with analyses from other windows to establish the relationships between them.
Event Reminder: BSMGP Autumn Lecture - Australia’s Stained Glass: Short History…Long Story with Bronwyn Hughes
10th September 2021, 7pm, Online via Zoom
Through a selection of stained glass windows installed in Australian architecture, this webinar will explore British connections and influence from the 1850s onwards, as both countries were changed by depression, war and economic circumstance. Stained glass windows, seen by many as decorative, can also be viewed as documents of art, architectural, and religious history, reflecting changes in society.
Tickets are £5 (£4.25 for members) and can be purchased at this link.
Call For Papers - International Conference
Glass in Museums: Research, Context, Communication
Bildungszentrum Adler, Historisches Museum Thurgau, Frauenfeld, 5 November 2022
Deadline for submission: 15 October 2021
2022 is the International Year of Glass. The United Nations is going to dedicate an entire year to this fascinating material, which will be discussed in all its facets over the twelve months. In the context of the theme it has adopted for the year, ‘Glas & Gloria. Fensterkunst im Thurgau’ (‘Glass and Glory. The Art of Window Glass in Thurgau’), the Historisches Museum Thurgau is taking this international focus as an opportunity to mount a conference that will examine glass from both its historical and museal angles. The conference is being mounted in collaboration with the Vitrocentre in Romont and at the same time will also constitute an opportunity to evaluate the work undertaken for the research project ‘Die Glasmalereien vom 14.–21. Jahrhundert im Thurgau’ (‘Stained Glass from the 14th to the 21st c. in Thurgau’), a project sponsored by Thurgau Canton and implemented by the Vitrocentre Romont, as part of the Swiss Corpus Vitrearum series.
While only a few museums have dedicated themselves entirely to glass art, there are significant collections of glass objects in historical collections. The transparency and fragility of glass pose challenges, but they also form the basis of our fascination with a material that has been in use for millennia. A range of issues make a multifaceted analysis possible: the significance of glass-painting as a vehicle for images, a significance closely intertwined with the medium’s own history; the employment of glass for everyday objects; its use in the fields of craft and art; and the technological aspects of the production and conservation of glass.
It is intended that discussion of the features of art glass held in museums and collections—whether as glass- painting, reverse glass-painting, vessel glass, or glass sculpture—as well as the challenges that it poses for museums will be divided into four sections. How can glass objects that have been removed from their architectonic contexts be exhibited in a new context? In this regard, what is to be gained through research into an object’s provenance? What opportunities are opened up for us by new communication media, both digital and virtual? To what extent should and can collection histories and earlier modes of presentation (for example, heraldic panels built into historical rooms) be included in exhibitions? What demands do glass objects make on the staging of exhibition space?
It is intended that the conference in Frauenfeld will promote exchange between experts in different disciplines and offer a forum for discussion of practice-based as well as theoretical and methodological perspectives. We welcome contributions that focus on the following subjects:
the scenography and staging of art glass in exhibitions
research into provenance in the field of art glass
digital story-telling: new ways of imparting information about glass
the conservation and restoration of glass
It is envisaged that papers will last 20 minutes. The conference languages are German, French, and English. Abstracts of a maximum of 300 words, together with a brief CV, should be sent by 15 October 2021 to [email protected] Some accommodation and travel costs can be covered.
This academic conference is being organized by the Historisches Museum Thurgau (https://historisches- museum.tg.ch) in collaboration with the Vitrocentre Romont (https://vitrocentre.ch).
