Abstract

Paraloid B-72 is a thermoplastic, non-yellowing, synthetic resin. Its composition can be chemically described as a co-polymer of methacrylate and ethyl-methacrylate. Due to its chemical stability, reversibility, good ageing characteristics, and its compatibility with various materials, it is vastly used in art conservation as a consolidant, adhesive, insulator, varnish. It is compatible with almost all materials. According to the previously obtained research results, Paraloid B-72 is sensitive to humidity, which may cause microorganism attack. This posed the subsequent question of its resistance to high temperatures and UV radiation. The overall aim of the current study is to determine the durability of Paraloid B-72 as a protective coating on wall paintings and stucco decoration in outdoor environments. The collated data could impact future decisions concerning the use of Paraloid B-72 as an effective protective material for such surfaces. Considering the complexity of the matter, and having in mind the research objectives, instrumental techniques for analytical chemistry were used, such as thermogravimetric analysis and IR spectroscopy. Some thermal-ageid and UV samples, which where treated through 302 hours (thermal) and 1072 hours (UV) showed low its stability, based on the changes visible on FT-IR spectra and thermograms.

Specialization: Sculpture (4th year of study)

Abstract

In the Roman Catholic Church, a tabernacle is a cabinet in which the Holy Eucharist is stored. The Gröden Valley, with their wood carving workshops in St. Ulrich and St. Christina has given perhaps the greatest contribution to the development of artistic craftsmanship and sculpting in the Tyrol area. The doors of Tabernacle crafted by Stuflesser usually display motives of the Passion of the Christ and grape vines (as perscribed by the Council of Trent), while the top arches of the niches are painted with plane depictions of a starry sky. This tabernacle originates from the sanctuary of the Chapel of the Sacred Heart of Jesus, located in the former "Betanija" sanatorium run by the Sisters of Mercy of the Holy Cross in Veli Lošinj. The tabernacle was found covered in a layer of dirt and soot, and were spotted dry drops paraffin wax. It was in stable condition, although with numerous areas of minor damage in the wood, preparation, and gilded layers, especially in marginal sections of the profilation. There was also spotted a partial overpaint (bronze powder in oil binder) which had at one time been applied over the damaged areas, but also covered some of the preserved gilded sections and metal parts (the key, door handles and candelabra). Parts of the restoration work still in progress include carving the missing parts of the capital profilation (balsa wood), filling in the shallower damaged areas of the damaged wood (grilith kit), chalk-glue preparation ( planatol kit toned with red bole), reconstruct the missing parts of the gilding, both matte and polished and retouching using gold leaves and gold powder. Finally, the entire object will be covered in a new layer of protective varnish. After completion of the restoration work, the tabernacle will be returned to the sanctuary of the restored Chapel of the Sacred Heart of Jesus in Veli Lošinj and returned into liturgical use.

Specialization: Wall Paintings and Mosaics (4th year of study)

Abstract

Archaeological excavations carried out in 2012 and 2013, at the site of Issa on the island of Vis, have revealed plenty of fragments of wall paintings dated back to the time of Antique Issa, or more precisely to the first century AD, when the baths, the forum and the theatre were built. Around thirty crates with fragments are the object of complex conservation activities at the Department for Wall Paintings and Mosaics at the Arts Academy at Split, while the rest is stored at the Archaeological Museum of Split, which conducts the research. The fragments are relatively well preserved and of high artistic quality. They were made by buon fresco technique in which pigments make a permanent bond with the plaster due to the carbonation of lime. Some of the fragments are monochrome. The others contain parts of geometric and vegetative patterns and animal and human figures. The exact contents of the paintings will however be clearer after the fragments are joined together.

Specialization: Archaeological heritage (5th year of study)

Abstract

The archaeological site of Dugiš is a prehistoric settlement of stilt houses located on the banks of the river Cetina. Being a very durable and resistant material, as well as the most characteristic feature of any prehistoric settlement, ceramic findings indicate a thousand year long continuity of living on the site. The fragments came from the Archaeological Museum at Split. The pottery was of everyday use, mainly cooking ware. 13 samples were selected, photographed under electronic microscope and analysed using FTIR. Most of the samples showed high contents of carbonates, oxides and metals. Only three of them contained higher levels of carbonates, which means that they were fired for too long. The one containing high levels of oxides was overfired.
These types of analysis provide more information on the prehistoric pottery making technology, as well as local clay contents and characteristics, which differentiate them from the imported wares.

Study programme: Integrated undergraduate and graduate course of study in conservation-restoration
Specialization: Metal (5th year of study)

Abstract

The object is one of 46 ancient coins found at the archaeological site of the former Roman colony of Mursa ( today's city of Osijek ), in the province of Pannonia. This particular coin was picked up not only because of its state of preservation, but also because of the interesting life and political significance of the emperor Aurelian whose head it portrays. The coin is made of copper alloy. When excavated, it was covered in soil containing calcite. The presence of the metal core was established by boring the coin with a needle. The coin also showed the type of corrosion commonly referred to as "bronze cancer". Soil and calcite accretions were eliminated with a scalpel, synthetic brush, and a micro-motor grinder with a flexible shaft. The stabilization process began with dipping the coin in the 3 % solution of benzotriazole in acetone. The coat of Paraloid B72 in toluene was used as the protective finish.

Abstract

The poster presents a brief summary of a arheological investigations and conservation restoration treatments of a floor mosaics in the historic core of Split. The mosaics in question are dated to the 3rd century AD. It is believed that they were made by the Salona workshop which was particularly active around that time. The mosaics are periodically restored, but being located outdoors and without a protective covering, they are susceptible to all sorts of damage. Since their discovery to date a significant part of the mosaics has vanished due to inadequate care.

Abstract

Dušan Džamonja sculpture park was founded by the artist  himself in 1960s and was opened for public in 1981. The sculpture park is located near Vrsar, Istra. The idea was to provide a place for artists to live, create and exhibit their work. It turned out to be a convenient solution to the problem of finding a place for display of Džamonja's large sculptures, as well. In 1997 Džamonja donated the sculptures to the Republic of Croatia and Vrsar Municipality. The sculpture park has been listed in the national  register of cultural monuments.

The purpose of the poster is to draw attention to the negligence of governing structures. The park is managed by the museum of Poreč and environs, but insufficient financial support and lack of interest in upgrading the conditions of the park make it difficult to maintain it. Some sculptures are in need of restoration, and the whole park needs a development plan regarding the security issues, conservation discipline and advertising strategy. The authors also examine the case studies of selected sculptures which illustrate the problems that affect them all.

Specialization: Metal (2nd year of PhD)

Abstract

Conservation and restoration of the historical firearms are characterized by individual and comprehensive approach to the historical substance. This is due to the specific design of weapons, the technical complexity of the construction of mechanisms, production technology and the multitude of used materials. As a part of conservation work there was made an attempt to develop a preliminary research methodology of historical black powder guns. The issue was discussed on the example of historic preservation process of: Arquebus with wheellock from the collection of National Museum in Cracow done within the diploma thesis on Academy of Fine Arts in Krakow. The study included: documentary images in visible light, infrared light and UV luminescence, microscope examinations. Another study focused on the analysis of the metal elements. There were made attempts to determine the quantitative and qualitative carbon content. The metal element were also examined using X-ray fluorescence spectrometry. There was also conducted hardness tests, endoscope observation, X-rays photography and computed tomography scan. It was necessary also to perform microbiological tests of wood. Performed conservation and restoration procedures have restored weapons aesthetic and historic value.

Abstract

This poster details the steps involved in the restoration and conservation of a 19th century pistol, type kubura ledenica. "Ice pistols" or ledenice are flintlock guns that appeared in the Balkan region since the 17th century. They were lavishly decorated and covered with silver. It was an integral part of the male folk costume until the mid 20th century and worn on special occasions.
This ice pistol that was restored and conserved was recieved in good condition. The silver parts of the gun oxidized and darkened with time. Iron–made firing mechanism and gun barrel were covered with rust. The pistol was disassembled and all of the parts were cleaned and conserved with chemical and mechanical processes. Main spring of the mechanism was found detached and had to be welded back in place. Finally, the iron elements were lacquered and silver polished.

Abstract

The wooden polychromed sculptures of St. Mary Magdalen and St. Margaret date from the 17th century and are held at the Museum of Samobor (Zagreb County). They are a product of the workshop of the sculptor Ivan Komersteiner, born in Germany. The sculptures were brought for conservation treatment to the Department of Conservation and Restoration of the Academy  of Fine Art in Zagreb in the summer of 2012. The treatment included the following steps: preventive undergluing of the polychromy, consolidation of the wooden support, analysis of the micro samples of the polichromy, removal of surface dirt.The stratigraphic analysis of the samples of the paint layers and the test probing confirmed that the polychromy was overgilded and oversilvered in the same order and manner as it was in the first chronological layer. This was confirmed by the chemical analysis of all layers, using X-ray fluorescence (XRF), a portable spectrometer designed by professor Vladan Desnica. Based on the results of the analysis, it has been decided that the scheme applied  over the original one, will not be removed.

Abstract

In October 2014, a pair of candle holders with angels arrived in the Department of Conservation and Restoration of the Academy of Fine Arts in Zagreb, Croatia , in a very poor condition. The angels were brought from the sacristy of Saint George the Martyr in Lešće na Dobri, Karlovac County, Croatia, which falls under the responsibility of the Conservation Department in Karlovac.  The mentor, Assoc. Professor Andrej Aranicki, and Tanja Horvatić, the art historian and senior consultant-conservator from Karlovac, agreed that the objects should be treated using the so called “galleristic” approach. Katarzyna Bizon (a student from Poland involved with the Erasmus programme) and myself carried out the conservation works on the angels. Katarzyna worked on them in the winter semester of the current academic year, and when she left for home, I continued work on both angels.

Abstract

The poster shows the issues which the conservator-restorer faces in everyday work, and refers to the question of the final presentation of the work of art, in this case a sculpture. Through several different examples the question of balance between conserving and restoring is attempted to be answered, and emphasizes the importance of context when deciding on the scope of the works required. Each work of art requires an individual approach, critical assessment, valuation and general context. In other words, there are many factors that affect the final decision making and each of them needs to be thought over. The task of the conservator-restorer is to firstly look at the complete history of the art piece and if possible to perceive its original function and appearance from any subsequent modifications. Priorities have to be set: before asking HOW to conserve-restore it is needed to ask WHAT to conserve-restore and FOR WHO? Interdisciplinary approach, expert discussions and education should be an integral part of contemporary conservation-restoration profession, so the works carried out can be of greater quality and in accordance with the principles and ethics of conservation and restoration.

The marble statue of the Emperor Augustus from Nin

UGRINA posterAuthor: Helena Ugrina, MA
Mentor: Assistant Professor Siniša Bizjak

Study programme: Integrated undergraduate and graduate course of study in conservation-restoration
Specialization: Stone (studies completed)

Abstract

This poster displays the conservation - restoration works on Roman marble statue (1st century) showing the posthumous Emperor Augustus. It represents just a part of the group of statues discovered during the 18th century archeological excavations in Nin. The statue belonged to the Danielli historical collection, called after it's founder dr. Danielli Tomasini who assembled the largest and most valuable collection of antiquities in Dalmatia, in the first half of the 18th century. In 1882, the collection came into possession of the seminary in Udine and later on they sold out the entire collection in an auction all over the Europe. In 1928 they were returned to Zadar.
Besides mechanical cleaning of the statue, the main challenge of the project was to ensure stability of the statue because it was surrounded with scaffolding in the lobby of the museum. Since instruments (like Cobalt 60) were not availble, the conservation and restoration staff of the Arts Academy decided to drill holes through the length of the brass fixings, and measure their depth using an endoscope camera. Stability is finally proven and statue of Emperor Augustus now stands freely in the newly opened antique department in the Archaeological Museum in Zadar.

Abstract

The conservation-restoration treatment of the painting Landscape with a Lake started in December 2013. The painting (56.01 cm × 91.5 cm) was made in 1918 (signature marking) by an unknown artist using the technique of oil on canvas. The painting was in a very bad condition, obviously due to inappropriate storage and handling. The painting was deformed. It had tears and many lumps and dents caused by mechanical impact. Since the canvas had gone slack, the lines of the inner edges of the stretcher bars were clearly discernible on its surface. The main goal of conservation-restoration treatment was to remove the causes of the painting’s decay (surface dirt), stabilize its overall condition, reinforce the canvas and the paint layers and improve the readability of the scene. Because of a previous conservation treatment, the emphasis was placed on the compatibility of materials.

Abstract

The paper is an abridged version of my undergraduate thesis, which was submitted to the Academy of Fine Arts and Design of the University of Ljubljana in June 2014. The thesis presents the problems I faced in attempting to conserve and restore the reverse painting on glass The Adoration of the Magi held by the National Museum of Slovenia. I begin by detailing the history and technique of The Adoration of the Magi before describing its blistered paint and other damage. Two ethically acceptable choices of conservation and restoration of the piece are discussed next: one is its full conservation-restoration, the other, only its preventive conservation. After deciding for the former, multiple trial attempts at cleaning the painting and consolidating its paint with different adhesives proved unsuccessful because they only partially removed the blistering. Since the use of adhesive would not have cleared the blisters and would therefore have caused unnecessary damage, I instead decided to create a case capable of securely storing the fractured painting. I also propose climate conditions under this painting, and others like it, can be stored.
