Abstract

SAWONIUK Alicja

The presentation concerns the research carried out by the author at the Academy of Fine Arts in Zagreb during her Erasmus+ exchange period, under the mentorship of professor Suzana Damiani. The project was dealing with self-cleaning coatings based on aqueous dispersions of titanium dioxide nanoparticles. Two products were analysed: CristalACTiV™ PC-S7 and CristalACTiV™ S5-300B.

Titanium dioxide is considered to be very promising material for cleaning organic pollutants: it is efficient, inexpensive, non-toxic, compatible with lots of materials. Due to its photocatalytic properties and super-hydrophilic values it is commonly used in industry, especially in outdoor environment. The present work was carried out in order to verify the effectiveness of titania dispersion with interior wall paintings in buon fresco technique. The aim of the project were experimental tests with cleaning and protecting painted surfaces from soot. The photocatalytic activity of the coating on treated surfaces was raised under natural and artificial UV irradiation. Several laboratory tests and analysis (wettability, colorimetry, water vapour transmission) were taken.

Abstract

CAREVIC MASKARIC PERKOVICThe subject of our presentation is a book Breve Compendivm Nationis Glorisae Totivs Lingvae Illyricae by the author Martin Rosa. It was published in 1638 and is situated in Franciscan monastery in Rožat. Martin Rosa was representative of Franciscan Illyrism. The book is written in Latin and tells about creation of the world, Slavic cultural and political history, their language, geographical position and it is the only remained copy in Croatia.

Process of restoration took place in workshop of paper at University of Dubrovnik. The book is made of three parts which vary in dimension, thickness and in type of print. Through this presentation we'll show the difference between the state of the book when it first arrived in the workshop and after the restoration, as well the old techniques of making water marks, print, etc... Every part of the book required a different approach in restoration process.The book was in very poor state and had many mechanical and chemical damages, especially book cover and binding, because of bad conditions in which it was kept.

MIKLOS MarcellAbstract

The topic of this presentation is the difficulties of the conservation (2015/16) of an exotic African sword with scabbard made of Nile crocodile and monitor skins being kept in the Museum of Ethnography. Through the cultural and historical classification and the identification of the reptile skins, this sword with its scabbard was turned out to be a very unique and special artefact originated back to the colonial period of Sudan. In the presentation the main tasks of the conservation will be discussed, such as the taking out the corroded and highly decorated sword from the sheath, the humidification and consolidation of the dried and fragile leather parts (including more than 100 strips), fixing other broken or damaged parts (horn, reptile fingers or the tail part of the sheath) and lastly, taking care of the safe storage of the object.

Abstract

POTRAWIAK MajaCracow Hodegetria type painting is an example of the phenomenon of a widespread repetition of one image that in such scale is uncommon in the history of art. The original, probably not preserved until today, was imported to Poland in the end of 15th century. The painting from the church in Przyłęk Szlachecki dated circa 1500 that is discussed in this presentation is an example of its copy. Its study and conservation was carried as a part of the master thesis at Jan Matejko Academy of Fine Arts in Krakow under the guidance of Anna Sękowska (PhD). The research revealed a complete overpainting of the image. The main issue was the 19th century background with chess board ornament due to its discordant style with no artistic values. Gathered information led to the complex intervention aiming to unveil the original painting layer and remove the later background. During the process, the traces of the original design of the background drawn on the panel were uncovered. This disclosure, along with an exemplar of the ornament from the painting from Chomentów created in the same workshop, served as the key indications for the reconstruction of the background in its possible original shape.

Abstract

PRAHIN MiaFrom the beginning of the study programme on the Department for Conservation and Restoration of Works of Art, part of the subject on Conservation and restoration of wall paintings is the exercise of transferring wall paintings. In this presentation different techniques of detachment of wall paintings and transfer to a new carriers are presented, including occuring problems. Detachment of wall paintings from the original carrier and their transfer are measures that have a major impact on wall painting and architectural objects which they are integral parts of. This fundamentally changes the composition and structure of the original work of art. Detachment and transfer are dangerous, drastic and irreversibile methods that severely affect the physical composition, material structure and aesthetic characteristics of wall paintings. Therefore, these procedures are justified only in extreme cases when none of the treatment options in situ are possible. The exercises of wall paintings transfers are performed on paintings that are painted by students of previus generations. They cover all three ways of detachment: stacco a massello (stripping the paint layer, layer of plaster and part of carrier), stacco (stripping the paint layer with a plaster layer) and strappo (stripping only painted layer). In this presentation only selected examples are shown derived using different materials and methods, various problems that occurred during work and ways in which they can be avoided.

Abstract

MILOSAVLJEVIC KatarinaGravestone monument – Krstaca belongs to the group of stone sculptures from the archaeological collection of the late Middle Ages. Finding site of the Cross was a cemetery at St. Peter's Church near Novi Pazar.Gravestone monument dates back from 17th/18th century. The object was found covered with deposits of calcination and surface impurities. On the back side three iron anchors, attached by an additional cement binder, were spotted. Ultraviolet and Infrared recordings, USB camera and photo documentation of the object were performed. Impurities were also photographed using an USB camera. After the sample was cleaned, it was determined that the object should be treated with alcohol, ultrasound and EDTA. Missing parts (lower right corner , entire left wing of the cross) were fixed with brass anchors to the original and painted in colors similar to those of the marble original. The mold was taken from the sculpted positives and mass made of marble flour, cement, quartz sand and silicate solution was poured into moulds. Documentation of the entire conservation and restoration process  was submitted to the National Museum of Belgrade, along with the object.

Abstract

KRALKA PaulinaWayang klitik is a rare and underresearched type of traditional javanese puppet theatre. The puppets are carved out of wood and have leather arms attached to the corpus. They are also polychromed on both sides. Study and conservation of five puppets from the National Museum of Ethnography in Warsaw collection, that is discussed in this presentation, was conducted as a part of the master thesis at Jan Matejko Academy of Fine Arts in Krakow under the guidance of Jarosław Adamowicz, PhD. It aims to provide a comprehensive insight into the technology of wayang klitik puppet making. Therefore, an extensive research has been carried out on identification of the materials used as well as the evaluation of the puppets` state of preservation and the extent of previous alterations and restorations. The gathered data enabled to propose and undertake the proper conservation treatment. A lot of consideration in the project is given to the design of suitable exhibit method that would ensure proper conditions and enable viewers to admire the puppets polychromy on both sides. Removable prosthetics of the missing pieces of puppets to assist interpretation during the exhibit are also discussed.

Abstract

OBLAK AnaThe subject of this presentation is a Baroque painting entitled Ecce homo painted by Leopold Layer. Initial examination of the painting has showed the condition of the painting is unsatisfactory, which can partially be contributed to the previous conservation work. In the continuation, two main issues were discussed. Due to high sensitivity of the cinnabar pigment used mainly on red surfaces, it was necessary for us to consider carefully, which cleaning method would not compromise the original material. Another significant issue was the highly deteriorated original canvas, as well as choosing the proper lining technique and materials. Also practical aspects of the conservation treatment were considered. The purpose of conservation-restoration intervention was to alleviate the obtrusive effects of the ageing process, including the unsuitable past interventions, by taking into account the basic conservation principles of reversibility and minimal intervention.

Abstract

DRAGAN BarbaraThe biomineralization method uses carbonatogenic bacteria to form biocalcite for the purpose of consolidating cultural heritage objects made of carbonate stones. The paper sums up my bachelors’ thesis, where I examined the effect of the consolidation of objects made of carbonate stones by the method of biomineralization. The very definition of the methods’ concept as well as the short process of the operation is presented. For the experiment, the commercial product Calcite Bioconcept, which contains two components: lyophilised bacteria Bacillus Cereus named Biocal and a nutrient called Nutrical, was used. The paper encompasses the presentation and the analysis of the results of colorimetry, drilling resistance measurements (DRMS) and the ultrasound velocity measurements (USV) before and after the consolidation. Measurements were carried out on laboratory samples of limestone and marble. Moreover, the description of the process of consolidation of a damaged marble relief, which is kept in Museum & Galleries of Ljubljana, is also included. Consolidation of the object proved to be successful, however, some improvements should be made.

Abstract

GRDJAN AnaThe baroque wall painting representing the scene The Shooting of Crucified Saint Cosmas and Saint Damian was investigated and subjected to various tests with the aim of developing an appropriate conservation-restoration concept. The final goal was to reestablish structural and aesthetical integrity of the damaged painting; overpainted, destabilized by cavities and intersected by shallow scratches in the intonaco. Performing the tests in situ, special attention was given to the selection of the appropriate cleaning methodology for various extraneous materials, starting from dry cleaning methods and then proceeding with chemical substances such as AB 57, ammonium carbonate and cation exchange resin. Besides the aforementioned researches and laboratory investigations of original and added materials, tests were also conducted in the OKIRU workshop. Simulations of scratches were done on plastered test plates. They were filled with different plasters recipes and textured to match the adjacent surface. The plaster which enabled appropriate surface treatment was chosen to be used on site. Various recipes of different injection materials (lime and quartz sand, CaLoSil "paste-like", CalXnova and PLM-AL) were also tested. Researches included material shrinkage, flow properties and the capability to fill object-specific cavities. The established conservation-restoration concept was applied in situ, with great care given to application methodology.

Abstract

MARIC JosipaThe presentation reports on the results of the analyses of pigment samples from fresco paintings and stone sculptures and the creation of a data-base of pigments in the Academy's scientific laboratory. It points out the importance of collaboration with professionals from other disciplines, especially chemistry. Understanding chemical composition and degradation process in heritage objects is crucial for their preservation for future generations. Identification of different pigments is important in deciding which conservation materials to use, foreseeing their reaction with the binding medium, the effects of the environment on the degradation processes and the effects of the conservation treatment itself. The analysis of the pigments will offer better insight into the composition and age of polychrome layers, while the future data base will make it possible to find the connection with other polychrome objects and find the place of origin. The pigment samples were examined by handheld digital microscope and analysed by Fourier Transform Infrared Spectrometry (FTIR), a technique already used for diagnostic purposes in conservation of archaeological heritage. The reliability of these measurements is very high even with extremely small sample sizes. Sample preparation is simple and the results of the analysis are quickly available.

Abstract

Nives Slemensek and Barbara KogojThe painting Lamentation from the 18th century is painted in oil technique on linen canvas. After analytical investigation of the paint layer and varnish, we discovered that the painting has two types of final varnish: the first layer of varnish, based on albumen and the second one, based on natural resin. Surface dirt was partially still adhered between the layers and on the top of the final varnish. In the past, consolidation of the paint layer and the ground with Aquazol has been carried out. This intervention had affected our further work. Different cleaning agents and tests were used. While we were doing tests for removing resin varnish, we found out they respond differently to the same agent on different areas. Based on the results, we chose two different cleaning agents for removal of the varnish. Dilemmas, possibilities and methodology for removal of the varnish will be presented in details.

Academy of Fine Arts, Vienna (Austria)
Study programme: Conservation and Restauration
Specialization: Objects, with focus on wooden objects (graduated in January 2016)

Abstract

Martin SiennickiThe presentation will deal with my diploma thesis, which concerns an originally probably 15th century great Pavise from the city of Kaufbeuren, Germany. Today the shield is in the possession of the Bavarian National Museum. Fire and neglect have caused severe damage and losses leaving the shield in a fragmented condition. Finding an object of this kind with nearly untouched condition is a rare instance, as many other remaining shields of this period have been already restored. Therefore the main focus in my diploma thesis was to investigate production processes and to analyse and identify materials used to build this shield. The man-sized, rectangular and slightly curved shield is composed in layers of different materials. On top of a core of softwood lies a layer of animal tendons. This layer is covered by an fire protection layer made by mixing spherical iron-containing slag particles, glass particles, bone meal and animal glue. The complete shield is enveloped with rawhide. The crest of Kaufbeuren forms the decor of the shield showing a golden oblique ribbon with two golden, six-pointed stars on a red background. Based on the material and literature research, a replica shield was constructed. The conservation treatment at the original shield was limited to a dust reduction by mechanical means and Cyber Clean Hypoallergenic®, and a consolidation of loose paintfragments with JunFunori® and Klucel H.

Conservation and Restoration Research of Summer Houses of Dubrovnik Area

Authors: Petra Ajduković, Anita Brakus Kedžo, Ana Doljanin and Veronika Meštrović-Šaran

Abstract

Kedzo ARestoration and conservation research conducted in November 2015 on three summer houses of Dubrovnik area brought forth a number of new cognitions regarding the state of these important monuments of Dubrovnik's culture. Our presentation would shortly, within the time limits, present the results of the mentioned research on Rastić, Boždari-Škarplenda and Gučetić-Lazarević summerhouses. Further, the methods used in this research will be compared to those used in the past research of years 1986 and 1987, conducted by the associates of the Art History Compartment of Historical Sciences Institute in Zagreb. Besides presenting the results itself, the significant role recently taken by other disciplines of science will be emphasized, with the aim of better understanding the cultural heritage and the cases and processes of their deterioration. The contemporary physical and chemical methods of analysis (microsecting/light microscope recording, FT-IR analyses, GR recording, SM light microscope analysis, AS qualitative and quantitative salt analysis, PA petrography analysis, XRD, X-ray diffraction etc.) and the most recent documentation methods (digital photography, 3D scan, point cloud, total cell) complemented the mentioned previous studies, which have more than 30 years ago warned about the necessity of reconstructing or at least recovering the damage that threatened to completely destroy certain parts of the buildings. Besides this, the comparison of the documentation regarding the current condition of summerhouses in the mid-eighties and the documentation of the most recent research, will give a clear insight into the volume and the types of damage and contamination amassed in the last 30 years.

The work presented in this lecture was carried out by a private company.

Study programme: Conservation and Restoration
Specialization: Textiles (3rd year of study)

Abstract

Ava HermannThe bicorn hat with fitted hatbox and two portepees are part of the permanent exhibition of the Franzensburg at Schlosspark Laxenburg in Austria. They were chosen to be restored at the Institute for Conservation (Head: Gabriela Krist), University of Applied Arts Vienna. The bicorn hat is conform with the clothing regulations of Emperor Franz Joseph's k.u.k army for a German general's Gala-uniform in the 19th century. As part of the conservation process, a report of the inventory and the condition of the ensemble were made. The mixed media objects are made of textile, wood, leather, metal, paper, cardboard, rubber and feathers and showed a strong mold infestation. Therefore, the conservation focused on the treatment of the non-active mold on different materials. The hatbox showed further damages, such as large tears and missing parts on the backside of the box. The leather parts of the box were infected with red rot. Important aspects of the project were securing methods for the preservation of the objects, as well as the stabilization of the decomposed leather. Due to the previous mold and beetle infestation, the exhibition conditions for the ensemble are crucial and should be considered in the future. For this purpose, a catalog for museum conditions has been elaborated and a fitting support for the bicorn hat and the portepees has been made.
