In a previous post I described a hanging scroll that I was working on – a work of Qing Dynasty calligraphy. It is now finished. I wrote then that I would explain the process used to conserve it, so here goes.

The first thing I had to do was to assess the scroll condition. The scroll is executed on paper – zhi ben hua long-fibered, which looks almost like silk. It was carefully analysed, photographed and the treatment procedure set. We next established the proportions and design for a new scroll mount.

A close-up of the scroll showing horizontal cracks

Unfortunately, the scroll was very creased with extensive horizontal cracks and signs of many previous repairs. However, the paint itself was stable and therefore suitable to be cleaned using a ‘wet’ treatment.

Using a broad paibi brush we carefully sprinkled water over the surface and drained it off.

Applying a wet treatment

When the painting was clean we could remove the old linings. A layer of dry xuan paper was placed over the face of the scroll, and the scroll and its support were loosely rolled up. The scroll was unrolled and flattened over wang wang juen (an open silk) face down and left overnight. During this time the paste and layers of backing papers became softer, making them easier to work with.

Removing the backing layers

To be able to remove the backing papers we had to remove many of the scroll layers. The scroll had three layers of backing papers – (i) a layer of white xuan paper repairs, (ii) a second lining of very long fibred paper and (iii) a first lining of thin xuan paper in direct contact with the calligraphy.

We cleaned the edges of the missing areas, removing old paste residues and lightly evened their thickness with a very thin spatula. Some of the previous repairs were in good condition and were left in situ, but some had deteriorated and so were removed. The calligraphy was now ready for relining.

Pasting the back of the scroll

Layers of paper were selected and dyed with natural pigments mixed with animal glue and water to match the tone. The back of the calligraphy was pasted with thin flour paste using a paibi brush. The first lining paper (a long fibered paper) was moistened and positioned over the calligraphy and adhered with a wuzhou brush. On top of this a second lining of mian lian (thin xuan paper) was pasted; this is called jia tou meaning additional lining.

False paper margins were adhered to the edge of the calligraphy to facilitate joining to its new silk mount later on.

Work continues on the scroll

When the lining was complete we could check the calligraphy itself. Missing areas were repaired with new paper made of mian lian and were evened with a thin spatula. The calligraphy was then turned face up and left to dry naturally.

Retouching the calligraphy

After sizing and drying, the calligraphy was again lightly moistened and adhered to a white xuan paper, face up on the table. We could now start retouching. This is done in natural light, and aims to match the repaired areas to the colours of the original. Ink and pigments are carefully diluted and then applied.

Preparing the scroll for mounting

This process was followed by tou liao, the selection and dying of the appropriate silk to form the new mount. The silk mount was to be in two colours, a plain and a grey-blue pattern silk.

Preparing the scroll for mounting

With retouching completed, the calligraphy was detached and the edges of the mount were squared. The mounting silk was cut to size and attached to the calligraphy using a technique called wa hua: a window is cut precisely in the silk and the calligraphy is inserted into it.

The scroll after treatment

A final double-layered backing paper completed the lining stage and, after a period of drying, wooden fittings were attached to the top and bottom of the scroll so it was ready for hanging. I will write about that in my next post…

#onthisday in 1939, just before the outbreak of the Second World War, archaeologists discovered the treasures of #SuttonHoo. It was one of the most important historical discoveries of the 20th century, and contained a wealth of Anglo-Saxon objects which greatly enhanced the understanding of the early medieval period. One of the most significant things to be found was an undisturbed ship-burial, the excavation of which can be seen in this photo. The 27-metre-long impression the ship left in the earth is highly detailed and was painstakingly recorded. The centre of the ship contained a burial chamber housing some spectacular objects – we’ll be sharing some highlights today.
#SuttonHoo #AngloSaxon  #archaeology #archive #blackandwhite This photograph shows a mountainside in #Angola featuring large engravings which may be thousands of years old. This rock art is found at Tchitundu-Hulu Mulume, one of a group of four rock art sites located in the south-west corner of Angola, by the edge of the Namib desert. The area is a semi-arid plain characterised by the presence of several inselbergs (isolated hills rising from the plain). Of the four sites, Tchitundu-Hulu Mulume is the largest, located at the top of an inselberg, 726 metres in height. There are large engravings on the slopes of the outcrop, most of them consisting of simple or concentric circles and solar-like images.

Our #AfricanRockArt image project team have now completed cataloguing 19,000 rock art images from Northern, Eastern and Southern Africa, and will be completing work on sites from Southern African countries in the final phase of the project. Follow the link in our bio to find out more about our African #rockart image project and the incredible images being catalogued.

Working with digital photographs has allowed the Museum to use new technologies to study, preserve, and enhance the rock art, while leaving it in situ.

As part of the cataloguing process, the project team document each photograph, identifying what is depicted. Sometimes images are faded or unclear. Using photo manipulation software, images can be run through a process that enhances the pigments. By focusing on different sets of colours, we can now see the layers that were previously hidden to the naked eye.

This painted panel, from Kondoa District in #Tanzania, shows the white outline of an elephant’s head at the right, along with some figures in red that it is possible to highlight with digital enhancement.

Tanzania contains some of the densest concentrations of rock art in East Africa, mainly paintings found in the Kondoa area and adjoining Lake Eyasi basin. The oldest of these paintings are attributed to hunter-gatherers and may be 10,000 years old.

Follow the link in our bio to learn more about the project and see stunning #rockart from Africa. This week we’re highlighting the work of our #AfricanRockArt image project. The project team are now in the third year of cataloguing, and have uploaded around 19,000 digital photographs of rock art from all over #Africa to the Museum’s collection online database.

This photograph shows an engraving of a large, almost life-sized elephant, found on the Messak Plateau in #Libya. This region is home to tens of thousands of depictions, and is best known for larger-than-life-size engravings of animals such as elephants, rhino and a now extinct species of buffalo. This work of rock art most likely comes from the Early Hunter Period and could be up to 12,000 years old.

Watch the incredible discovery of this colossal statue, submerged under the sea of thousands of years. This colossal 5.4-metre statue of Hapy was discovered underwater in what was the thriving and cosmopolitan seaport of Thonis-Heracleion. It once stood in front of a temple and would have been an impressive sight for traders and visitors arriving from the Mediterranean.

Come face to face with the ancient Egyptian god Hapy for yourself in our‪ #SunkenCities exhibition, until 27 November 2016.

The discovery of this stela, which once stood at the entrance of the main entry port into ancient Egypt, was an extraordinary moment. Its inscription detailing taxes helped solve a 2,000-year-old mystery!

This magnificent monument was crucial to revealing that Thonis (in Egyptian) and Heracleion (in Greek) were in fact the same city. The decree was issued by the pharaoh Nectanebo I, regarding the taxation of goods passing through the cities of Thonis and Naukratis, and it originally stood in the Temple of Amun-Gereb. The inscription states that this slab stood at the mouth of the ‘Sea of the Greeks’ (the Mediterranean) in Thonis.

A bilingual decree found in 1881 refers in its Greek inscription to ‘the Temple of Heracleion’ and in hieroglyphs to ‘the Temple of Amun-Gereb’. Together these objects revealed that Thonis and Heracleion were the same place.
