Kintsugi: Aesthetic Value-led Conservation


Kintsugi is a traditional gold-joinery ceramic restoration technique. It restores the practicality and functionality of broken objects, while adding decorativeness. Influenced by the culture of Wabi sabi, Kintsugi stresses significance in the aesthetic value of objects. This poster presents the origin and cultural background of kintsugi, and its dialectical vision of authenticity.



Eva Hesse's Latex and Fibreglass Sculptures: A Case Study in Contemporary Conservation

 


Latex and fibreglass sculptures of pioneering artist Eva Hesse present a number of contemporary conservation challenges including rapidly degrading and fragile materials, conflicting commentary from the artist, arguments for and against refabrication, and the possibility of unstoppable destruction. 

No Object is an Island: the necessity for collaboration in Conservation Practice



Conservation is a specific discipline, but it does not work on its own. In order to successfully start the conservation process, participation in the decision-making process is important from the international level, to internal museum departments to smaller external interest groups.   

Preserving Moments: Challenges in the Conservation of Street Art


    Street art conservation is one of the more prominent and contentious topics in the field. This poster begins by briefly defining street art, framing it within the body of cultural heritage. Issues of legality, authenticity and practicality in its conservation are addressed. This is then highlighted through a case study of the recently ‘missing’ Bristol Banksy Gorilla.





Challenges between contemporary art and conservation work

 


Nowadays, the conservation of contemporary art becomes an important challenge. In this poster, the general introduction of contemporary art is given at first, and then the challenges occur during conservation. Finally, Damien Hurst's 'The Physical Impossibility of Death in the Mind of Someone Living 1991' is represented as case study.

How Can Conservators Aid Conflict Recovery?


 

Over fifty world heritage sites are currently at risk, many of which are as a result of conflict. This poster demonstrates that an integrated approach of legislation, interventive conservation and training for local and governmental groups is the most effective way for conservators to aid conflict recovery.

Values-Led Conservation in a Small Museum: A Case Study From the Museum of Peoples and Cultures in Provo, Utah


 This poster explores a case study of values-led conservation at a small University museum in Utah. The conservation of a collection of Andean textiles is discussed in relation to the values and resources of the institution.

Here today, gone tomorrow: Questions posed by the work of Ai Weiwei to the conservation process


Both makers and users of contemporary art are questioning values that underpin the conservation process. The work of Ai Weiwei, as this poster illustrates, neatly encapsulates one such challenge. Through reconfiguring and destroying Neolithic vases’ Ai pose’s questions about the value attributed to original material or specific conditions. 

A Tale of Two Contexts: Values-Led Conservation, Whose Values?

There have been increasing debates about how to safeguard objects that are held by Western museums but originate from a non-Western culture. Value interpretation of these objects is a constant challenge in conservation practice. 

The poster demonstrates the possible divergence of value perception occurred in different cultural contexts, hoping to improve the understanding of the significance of a holistic value-assessment approach in any conservation effort. 

 



Participatory Conservation and the West's Superiority Complex


Participatory conservation is necessary when dealing with cultural heritage. The conflicting values between western scientific methods and intangible beliefs held by indigenous communities needs to be resolved through a compassionate and collaborative approach. This poster discusses the importance of preserving human connection and the intangible aspects of artefacts.

Restoring cultural loss: conservation and restitution

 


This poster explores the role of the conservator in restitution debates. Recent emphasis on the preservation of intangible cultural heritage can be used to consider colonial taking as an act of cultural loss. Replicas have the potential to fill the material void after restitution, while also gaining new significances. 

What can conservators do to aid recovery?




 This poster explores what can be done before and after a disaster or armed conflict to speed up the recovery process while retaining value within the local community. The fire at Notre-Dame Cathedral was chosen to display the effectiveness of a disaster recovery plan when conveyed to response teams.

The Value of Vandalism: The challenges that conservators face when considering the conservation of street art

Street art can be simultaneously viewed as both an art-form and a crime. This presents conservation decision-makers with a range of considerations concerning its historical, illustrative and social value. The poster examines historically significant works of graffiti and the complications inhibiting the creation of an applicable conservation framework.

 

The Challenges of Conserving Appropriation Art



 This poster explores the practice of artists using pre-existing objects which can pose many challenges for conservators in both ethical and technical decision making.


Emerging Conservation Dilemmas: How to treat new and mixed media in contemporary art?



Challenges of conservation in the territory of contemporary art mainly originate from its new and mixed media. This poster highlights four questions for conservators to notice and understand the significance of identifying special characteristics of each item, reflecting their practices and roles facing complex conservation situations.

Object J.0014: Manilla Currency Piece - By Ellen Seidell


J.0014 is a manilla currency piece composed of a copper alloy material. The object is roughly 11.0 centimeters long and 10.5 centimeters wide with a spiral height of 4.0 cm and is composed of one thin strand of metal that has been twisted together approximately 45 times to form a rigid, semi-coiled bracelet. No clasps or mechanisms have been used to connect the ends of the bracelet most likely due to the fact that the material is inflexible and would have loosely fit on the wearers wrist or ankle. Compressed soil deposits can be seen in the grooves of each coil, obstructing some details of the piece. In addition, four locations possess mild copper corrosion that is blue-green in color, though there are no signs of flaking or powder to suggest instability or bronze disease. Given the light corrosion and present soil deposits, it appears that no previous treatments have been performed. Overall, the artefact is stable and no changes are necessary for its current storage. 

Excavated in the Calabar Province of Nigeria by M.D.W. Jeffreys between the years of 1890 and 1954,   
J.0014 is believed to have been a ‘Bochie’ style manilla that would have been used for value judgements during ceremonies such as weddings and burials. This style of manilla differs from the general currency manilla that was mass produced between the 15th and mid 20th centuries both in Africa and European countries like Spain, Portugal, Britain, and the Netherlands. General manillas were no longer recognized as a currency in 1948, however, natives of the Calabar Province reluctantly took to this mandate and still continued to utilize all types of manillas in ceremonies and local trade. In particular, general currency manillas and those like J.0014 were composed of a transactional iron or copper, also known as ‘red-gold’ in Africa. The weight and size of the manilla would determine its value; J.0014 weighs a total of 440.0 grams which is lighter than some that weigh as much as 2300 grams. 

Due to the international production of manillas and their continual circulation for multiple centuries, the exact provenance of J.0014 remains unknown. Often when foreign manillas were brought to Nigeria, their metal would be recycled by local craftsman and forged into other manilla forms. Since J.0014 was used for ceremonial functions, it may have more likely been forged in the Calabar Province, though this would need to be validated using instrumental analysis such as X-Ray Energy Spectrometry.

B.0073 Nigerian Quiver and Arrows



Object Description

                B.0073 is a bamboo quiver with four arrows (Figure 1) from northern Nigeria.  Altogether they artifact is 70 cm long and weighs 264.5 grams.  The arrows are made from iron and bamboo.  Arrows A and B have plant-based wrappings at the end of the bamboo shaft, near the nock, and on the arrowhead’s shaft which help fix it to the bamboo shaft.  Arrows C and D appear to have sinew wrappings instead, but otherwise are of the same design as arrows A and B.

Figure 2. X-ray of Arrows A-D

Arrow A (Figure 3) weighs 27 grams and has a length of 71.9 cm. 

Figure 3. Arrow A

 
Arrow B (Figure 4) weighs 28 grams and has a length of 70.9 cm.

Arrow C (Figure 5) weighs 38 grams and has a length of 71.5 cm. 

Figure 5. Arrow C

Arrow D (Figure 6) weighs 37.5 grams and has a length of 71.1 cm. 

Figure 6. Arrow D

Object Biography and Statement of Significance

            Dr. Michael Garfield Smith, who was the head of the Anthropology Department at UCL from 1969-1975 donated the artifact to the Material Culture Room.  Unfortunately, there is no record of exactly when he donated it to the MCR.  Additionally, it is unknown exactly where and when he acquired the artifact, but he did conduct numerous field research expeditions to northern Nigeria throughout his career. His first trip to Nigeria was from 1949-1950, and again in 58-59, 1972, with the last time being in 77-78.

Throughout history and even up to modern times, the bow and arrow has been an essential party of daily life for many Africa tribes that inhabit the regions of northern Nigeria.  Its chief use is to hunt game and associated goods like animal skins or horns.  Additionally, in some areas tribesmen use bow and arrows to hunt fish in rivers and streams.  Successful hunts brought not only food to the tribe, but helped the chieftain maintain his status.  In addition to hunting, the bow and arrow remains a key aspect of warfare between tribes.  Arrows are also an economic commodity in some areas, as not all tribes have access to blacksmiths to make new arrows. 

Assessment of Condition
                The artifact is in good shape, although the quiver is missing its leather sling.  There is some discoloration from use and exposure to sunlight.  The most obvious issue is corrosion forming on the iron arrowhead (Figure 7), which requires future intervention.  Additionally, the sinew wrappings on arrows C and D are beginning to fray (Figure 8).

Object Assessment : K. 0010 - Flute

1. Object description

K. 0010 is a flute from UCL the Ethnographic Collections (Fig. 1). The object composites three parts: horn mouthpiece, long wooden stem and linen string that connected these two objects. The materials of the flute are bone, wood and linen.





Fig. 1 Photo of K.0010, the flute (Source: UCL the Ethnographic Collections, 2015).



The length of the wooden stem flute is 749mm (UCL Ethnographic Collections, 2020).

The horn piece was shaped by reductive method – removal of the sharp end. It can also be observed that there were decorations pattern craved on the horn mouthpiece (Fig. 2).



Fig. 2 Photo of the craved decorations on the horn mouthpiece (Source: Author, 2020).



It is predictable that the original material of the wood was millet millet–stalk (Fig. 3) which was one of the manufacture traditions of Flani (one of the composed members for Yauri Emirate) vertical flute (Erlmann, 1983).


Fig. 3 Photo of African vernacular fencing using millet-stalk which indicate the appearance and properties of this material (Source: Pinterest, 2020).



The wooden flute was shaped by cutting away as obvious tool mark can be observed (Fig. 4). There are three holes on the main tube of the instrument (Fig. 5).



Fig. 4 The trace of tool marks is indicated in the picture (Source: Author, 2020).





Fig. 5 The photo of holes on the tube (Source: Author, 2020).



Bite mark can be observed on the horn piece (Fig. 6). It can be deducted that horn piece would cover the narrower end of the wooden stem when performed (Fig. 7) and the musicians would place his/ her mouths on the horn and fingers on the holes (Fig. 8).

Fig. 8 Sketches of how to use the flute by according to author’s imaginary and deduction (Source: Author, 2020).



2. Object biography and Statement of Significant

2.1 Object biography

The owner of K.0010 is P.G. Harris. The details of the object are included in his book ‘The Yauri Day Book’. It can hence be predicted that the object was discovered in Yauri Emirate. Yauri was a historic kingdom and traditional emirate (Encyclopaedia Britannica, 2020), located in the north-western corner of Sokoto State, Nigeria (Salamone, 1985, p. 141) (Fig. 9). However, the content of the book is not accessible and instead, only several publications about Yauri Emirate are available. Resulting that there is a huge blank in object’s own biography.



Fig. 9 Reconstruction of the old Yauri Kingdon (Source: Harris, 1963, p.285).

2.2 Statement of Significance

Due to the limited accessible information available, the object can only be decided containing historic and aesthetic values.

2.3 Historic Value

The historic value of the flute, lies in that it was a witness of this British colonial history and Yauri Emirate’s history.

2.4 Aesthetic Value

The craftsmanship of the flute exemplifies the aesthetic value of the flute as it represents the indigenous and folk culture in Yauri Emirate that is unique among all other musical instruments around the world.

Object Assessment: M.0049 – Shrine of the Hand (“ikegobo” in Edo language)

This shrine was collected by Dr. R. E. Bradbury, the first social anthropologist to conduct extensive in-depth research in the Benin culture, probably in his last Benin tour in Nigeria in 1956-1961 (Gore, 2007, p.3; Bradbury, 1971, 1961). Carved by an Igbesanbhan, wood carvers who served the king of Benin, this shrine belonged to a wealthy, prestigious Bini warrior chief in Benin city. It is an endangered craft and a documentation of the local Cult of the Hand practices, in the times of dramatic social-political and change under British colonization (after 1897) and the independence of Nigeria in 1960.

A cylindrical, dark brown wooden sculpture with a dimension of 24 cm (H) x 22.2cm (D), it is carved from a block of heartwood of an unknown species of hardwood (might be kola nut tree or afzelia) (Ben-Amos, 1979, p.322, 1971, pp.79–80; Dark, 1973, pp.58–59). It is decorated with human figures and motifs on its top and vertical side with chisels, knives and a comb-like tool, mainly divided into 4 zones (Fig 1a-h): (i) a rectangular motif divided by a line in the middle (Fig. 1a), (ii) a main band of human figurines and motifs (Fig. 1c-h), (ii) a zigzag pattern of isosceles triangles with called ‘cloth of Ijebu’, (iii) a guilloche design of two wave-like ropes called ‘oba iri eva’, meaning guilloche with two ropes and continuous.

Fig. 1c Left side of shrine. An attendant consecutively supporting his master’s hand and holding a fan that symbolises accumulation of power and wealth.


Fig. 1d Front (centre) of the shrine. A chief is depicted in chains of crossed straps of coral beads and a wrapper, carrying a sword of authority in his right hand (The Museum of Primitive Art, 1974, p.10; Ezra, 1992, p.108). His hands are held by two attendants on each side. A bottle of palm wine, which a symbol of wealth, is carved next to him.


Fig. 1e Right side of shrine. An attendant is supporting his master’s hand while holding a shield with two spears in another hand.


Fig. 1f Right side of the shrine. A third attendant in the same outfit is carved. He has a sword in one hand and a spear impaling a human head on another hand.


Fig. 1g Back of the shrine. The upright, clenched right fist with an outward pointing thumb is the main motif of the cult of the hand symbolising ‘gathering up riches into one’s own hand’ (Ben-Amos, 1980, p.60).


Fig. 1h Back of the shrine. A feather of the vulturine fish eagle (igan-oghohon no-k’uhumw’ivie-), the feather worn by the chiefs on their beaded headbands, symbolizing high rank (Bradbury, 1961, p.136).


Unlike other type B ikegobo (Fig. 2a & 2b)(Bradbury, 1961), it does not come with a base or a peg on its top for supporting a tusk. It is generally stable with signs of previous pest infestations, multiple cracks, missing chips and other damages due to abrasion and usage (Fig. 3a-c). A dead larva or skin of an unknown pest is found in a large hole near the bottom (Fig. 4).

At the area of missing chip at the rim, a lighter reddish brown is revealed (Fig. 5). This darkening of colour on the surface of the wood might be due to prolonged exposure to UV, wood toning (e.g. wax or oil), or polishing with shoe polish (Unger et al., 2001, p.47; Florian et al., 1990, p.98).

No significant fluorescence, evidence of use of pyro technology (e.g. burn or charred marks), sign of separate material or previous repair (e.g. adhesive) is found under visual and UV examination (Fig. 6a-d). Tool marks remained on its uneven surface under raking light and no parallel or concentric grooves of sanding with sandpaper is found (Fig. 5)(Florian et al., 1990, pp.87–88).
