Madrid Study Trip

At the beginning of June, the Interns, students and two staff members of the Hamilton Kerr Institute travelled to Madrid for the annual study trip, visiting the cultural highlights of the Spanish capital and some of the major conservation studios. We enjoyed the hospitality and refined culinary traditions of Spain, guided by second year HKI intern Carlos González Juste who lived in Madrid before moving to Cambridge.

Casa de las Conchas

The day after we arrived in Madrid, we travelled out of the city to visit Spain’s oldest University Town, Salamanca, a UNESCO World Heritage Site. One of the city’s most remarkable buildings is the House of the Shells, or Casa de las Conchas, a late gothic palace covered with stone carved shells. Hidden away in Salamanca’s back streets is the Museum of Art Nouveau and Art Deco that houses a collection of remarkable glassware, furniture, dolls and paintings by Ignacio Zuloaga.

The Crown of thorns

Our first studio visit took us to the headquarters of the Instituto del Patrimonio Cultural de España (Cultural Heritage of Spain), located on the outskirts of the city. The circular building is one of the most remarkable architectural structures of the 1960’s, and is nicknamed “the Crown of Thorns”. After visiting the entrance hall, library and rooftop terrace we were guided around the sculpture and painting conservation departments, as well as the laboratories. We were introduced to the materials and techniques used in the making of traditional Spanish baroque sculptures, like the laying-in of glass eyes, use of ivory teeth and genuine hair in the representation of saints.

Hidden studios

In one of the narrow streets in the centre of Madrid lies the private conservation studio ICONO I&R S.C. We were guided around by co-owner and conservator Rafael Romero Asenjo, specialist on 17th century Spanish still-lives, some of which we admired while touring the studio. At the end of this exciting day, we walked to another hidden gem, the rooftop of the Círculo de Bellas Artes to enjoy a panoramic view of the city.

Back to School

On our third day we visited the Escuela Superior de Conservación y Restauración De Bienes Culturales, where our colleague Carlos trained as a conservator. We were introduced to the four year BA- and one year Master program and guided around the studios housed in a 17th century palace. In the wall-painting conservation studio , a monumental canvas painting was currently being treated. The numerous bullet holes that perforated the painting were a reminder of the violent civil war that raged through Spain in the 1930’s. Other highlights of our visit included a roman pillar with ancient graffiti, traditional Spanish fans, paintings on glass supports and the challenging support treatments in the panel paintings studio.

In his Majesty’s service

Inside the magnificent Palacio Real de Madrid are located the conservation studios and Royal workshop of the King. We walked through a long corridor with a seemingly infinite amount of doors on either side. Behind every door was housed a different studio: clocks, paper and book, painting, metal…

The first room we entered was the studio responsible for the maintenance and repair of the ca.700 clocks, tower bells, music boxes and organ pieces dispersed over the Royal palaces. The specialist skills required for this work takes many years of practice, and has unfortunately become a dying trade.

In one of the studios, we saw a rare piece of royal transport history, the litter used by the elderly Emperor Charles V. After visiting paper and book conservation as well as frame conservation, we arrived at the studio designated for the treatment of small scale paintings. On the easel stood a delightful Madonna and Child by Quinten Massys which was in the process of having its varnish removed. The conservators often work on location for larger pieces, like the treatment of the monumental Crucifixion by Rogier van der Weyden kept at the Escorial Palace. Just next to the Royal Quarters, right on the first floor of the Palacio Real, a painting conservator was finishing the treatment of several large pieces by the neoclassical painter Anton Raphael Mengs, a favourite of Charles III of Spain.

The surface of Guernica 

Spain’s national museum of 20th century art, the Museo Nacional Centro de Arte Reina Sofía, houses a world renowned collection of modern art. The most enigmatic work of its collection is Pablo Picasso’s magnum opus: Guernica. A team of conservators and computer technicians have recently completed an imaging project, scanning the monumental canvas in high resolution. This makes the monitoring and studying of the painting’s fragile surface much easier for conservators and art historians. The team of 22 conservators are mainly involved in the loan requests the museum receives, preparing paintings for transport and assessing their condition. Most treatments are limited to stabilising the artwork and minimal intervention, as modern and contemporary artworks present challenges the conservation world has not fully mastered yet.

Garden of Earthly Delights

The Museo Nacional del Prado is a true garden of delights for the art lover, where the walls are adorned with works by Titian, Van der Weyden, Rubens, Velázquez and Goya. The conservation studios have recently been moved to the museums new extension, the former monastery of San Jerónimo el Real. We were shown some of the panel support systems that were developed by the Panel Painting Initiative, a project that was conducted with the help of the Getty Conservation Institute. After discussing some of the treatments, we moved to the museum’s laboratory. The imaging facilities and analytical techniques employed by the scientists are tailored to answer specific questions asked by curators and conservators. In recent years, the laboratory has conducted ground-breaking work on the analysis of historic materials used in Spanish paintings, especially the composition of ground layers.

*For security reasons, no photos were allowed to be taken during the tour*

Following the studio visit, we went to see the blockbuster exhibition on Hieronymus Bosch, better known in Spain as El Bosco, and an exhibition on the French baroque artist Georges de La Tour.

The ghost of El Greco

On Friday we took the train to the nearby city of Toledo, a medieval stronghold which history goes back to Roman times. The astonishing buildings and structures across the city are a reminder of Toledo’s complex cultural and religious history. The Cathedral of Saint Mary of Toledo houses many 15th century altarpieces and the recently restored Disrobing by El Greco. The artist lived in Toledo for most of his life and many of his paintings have been preserved in Toledo’s churches and monasteries. In the Santo Domingo el Antiguo, the local nun pointed out a hole in the floor, where the artist is supposedly buried. Before we travelled back to Madrid we acquired a few bags of the famous Toledo marzipan, in the hope to make it last until we were back to England.

Our study trip to Madrid, on top of being sunny and full of delicious food, was an absolute delight as there were so many beautiful artworks and buildings to enjoy. The Bosch exhibition was everyone’s favourite, and we would like to encourage people to kill two birds with one stone by going to see it when you visit Madrid, as many of the paintings belonging to the Prado, such as the Earthy Delights, will never travel in order to preserve the condition of these masterpieces.

Eton College In-Situ

In late May 2016, fellow Post-Graduate Intern Camille Polkownik, Director Rupert Featherstone, and I worked on a number of paintings at Our Lady of Sorrows Chapel on the campus of Eton College, located near Windsor Castle.

Over the course of three days, we treated eight paintings on site. While this in-situ project involved a number of procedures routinely carried out under such circumstances, including consolidation, surface cleaning, minor tear repair, minor filling and retouching, varnishing, and conservation-standard re-framing, we encountered a number of slightly unusual challenges that warrant mention.

Two of the paintings, upon closer inspection, were found to consist of paper adhered to canvas, which was in turn attached to keyable stretchers. These paintings appeared to have been executed in an oil-type medium and had darkened coatings, possibly tinted to make the paintings look older. Extra caution was taken during surface cleaning as a result of the potential sensitivity of the paper supports to water. After some testing, the solution settled upon was to use a lightly dampened “Blitz-Fix” sponge and dry the surface immediately with Kimwipes (acid-free tissues).

Additionally, while saliva or deionized water at pH 7 or 8 on cotton swabs would generally suffice for surface cleaning varnished paintings, two paintings – one varnished, one unvarnished – were found to warrant the use of a cleaning solution with a low percentage of an added chelator on cotton swabs due to the significant amount of tenacious grime present. These paintings, previously appearing rather dull and grey, underwent dramatic visual improvements after surface cleaning. Re-varnishing these paintings was also necessary and provided aesthetic benefits.

For health and safety reasons, the choice of which varnish to use while on an in-situ can oftentimes be limited to the synthetic varnish requiring the least harmful solvent. Fortunately, we were able to time the progress of our treatments such that we could varnish at the end of the second day prior to leaving the building, preventing human exposure to solvent vapours. This allowed us to use Paraloid® B72, for example, which we found particularly beneficial to employ on paintings with uneven gloss.

Framing and hanging presented a few challenges as well. We needed to consider several special modifications when re-framing the paintings, including enlarging the rebate of one of the free-standing frames, since the painting didn’t quite fit. The college staff also took the opportunity to modernise the hanging hardware.

It was a privilege to participate in this project at Eton – not just because we were treated to Eton College behind-the-scenes, or because we managed to fit in a few strolls in the evenings to see the incredible number of swans on the river! It was a pleasure to work in such a lovely space, and it was a valuable learning experience to encounter such a range of conservation issues on site.

Many thanks to the welcoming and supportive staff at Eton College for inviting us to work on site. We hope that the congregation of Our Lady of Sorrows appreciates the aesthetic improvement of the paintings and that our efforts have added to an enjoyable experience of the chapel.
