Wacław Szymborski (1 8 9 8 -1 9 6 8 ) was born in Częstochowa but his whole life was connected with Cracow where he graduated from the Academy of Fine Arts and, already during his studies, began working as a conservator. His greatest accomplishment was the conservation and execution of copies o f the cordwains purchased in Moritzburg for the Wawel Royal Castle. For the purposes o f this task, in which he was involved from 1928 to 1948, Szymborski was compelled to become acquainted with the technique o f the cordwain. He organised a special workshop on Wawel Hill with up to twenty helpers. He also designed and personally made the necessary tools (models and decorations o f the leather). In 1938 and 1939 Szymborski was awarded prizes at international exhibitions held in N ew York and Saloniki. He was also a conservator o f paintings, including the Racławice Panorama (1 9 5 0 -1 9 5 6 ). His other achievements are leather cordwain covering o f his own design for the Madonna chapel in Jasna Gora and a baldachim for the presbitery o f the Warsaw cathedral. The postwar situation in Poland was unfavourable for Szymborski, whose years were connected with dire financial difficulties. From the perspective o f over a quarter o f a century from his death it appears that Szymborski was insufficiently appreciated. Despite the enormity o f his work, the number o f publications and documents about him remains very modest.

Disinfection of moulded water colours and pastels creates much difficoulties during their restoration. Therefore studies on the selection of fungicides and methods of their application were pei’formed. The purpose of our work was to study the effect of solvents and fungicidal vapours on water colours and pastels in order to establish a non-damaging method of their disinfection. As water colour samples served paints from 4 different panels of contemporary production (total of 57 paints) From among different kinds of pastels 96 were used in our study. The influence of various organic solvents (ethanol, acetone, benzene and ether), the vapours of fungicidal solutions, sublimating fungicides (without solvents) and gaseous disinfectant Rotanox (ethylene oxid) on the above paints was investigated. Among the fungicides used, were : p-dichlor-benzene, p-chlor-m-cresol, sodium p-chlor-m-cresolate, phenyl mercuric acetate and sodium о-phenyl phenolate. The efficacy of disinfection of water colour samples and pastels by sublimating fungicides was circumscribed. Also their preventive ability against the fungal development in future was established. The method of disinfection was veryfied on 2 moulded pictures from Polish museums : M. Łada — „My grandmother” (pastel) and A. Kędzierski — „The reaper” (water colour). The results obtained show a strongly harmful effect on the paints studied of vapours of the solvents and fungicidal solutions. The main damages of paints under the influence of these chemicals were : the solubilization < f paints, their migration into the paper medium, their f dening and/or darkening. The most secure was the disinfection with the vapours of sublimating fungicides or Rotanox. The best results were obtained with vapours of p-chlor-m-cresol, phenyl mercuric acetate and Rotanox. The proposed method of disinfection of water colour, and pastels is as follows : 1. Prepare filter paper sheets and the polyethylene bags of the same size as the moulded picture. 2. Saturate the above mentioned filter paper with ethanolic solution of PCMC (10%) or OFR (1%) and remain to evaporate the solvent. 3. Put the picture between the impregnated filter paper sheets in polyethylene bags and secure with adhesive tape. 4. The pastels with weaken paint layer have to be disinfected in polyethylene cameras or in bags forming inside them higher edges of pasteboard. 5. The time o f disinfection for PCMC is 7 days at 23°C and for OFR 3 days at 40°C. The ethylene oxid — Totanox gives a full sterilizing effect after 24 h but doesn’t prevent the objects for future time.

The quaternary ammonium salts are well known disinfectants used in hospitals for cleaning of infected surfaces, washing etc. and also in paper manufactories for protecting of paper againts fungal attack. The USSR authors recommend to use these compounds for disinfection of panel and mural paintings. Sterinol is the Polish POLFA product containing the 10% water solution of ammonium dimethyliaurylbenzyl bromide.. In our studies Sterinol was treated as 100% liquied for diluting. The following properties of Sterinol were studied: 1. The concentrations o f Sterinol contained in media for inhibiting the development o f bacteria, their spores and fungi ; 2. The concentrations of Sterinol for disinfecting the mildewed samples of anciend papers in static and dynamic washings (temp. 23° and 55°C); 3. Influence of Sterinol washings on the solubility of inks, China inks and printing paints. The results obtained: 1. Water solutions of Sterinol may be recommended for disinfection of mildewed ancient papers; 2. The highly disinfecting effect against bacteria and fungi show 5,0, 7,5 and 10% solutions at the temperature 50—55°C. In room temperature (20—23°C) 10% Solutions of Sterinol have good disinfecting properties ; 3. Because of its detergent properties Sterinol can be used also for cleaning dirty papers the concentration of 3—5%. 4. Proposed method of disinfection : Prepare the sterilizing washing containing 7,5% of Sterinol (75 ml in 925 ml) of hot water (50—55°C) in suitable beaker and immerse into the paper object. Softened dirt and fungal growth are removed by delicate brushing. After cleaning the paper is placed in fresh solution of Sterinol and left for some minutes. Then it is recommended to rinse the paper in in distiled water to remove the residues of Sterinol. After carefull rinsing the paper must be dried between filter paper sheets. The strongly weakened papers must be cleaned and disinfected by placing then between two nylon nets or on the glass. 5. The above mentioned method may be safely used for printed books and to uncoloured prints. For manuscripts it might be used after establishing the insolubility of inks. 6. Sterinol solutions are also recommended for easy and quick disinfection of laboratory instruments, surface (tables, shelfs) and hands after the work with mildewed objects. This desinfectant is not toxic for men.

The article contains a survey of the state of knowledge about the additional tanning and currying of old leather, with particular attention paid to book bindings; both operations are regarded as the most important in the entire process of conservation. The authors present a lucid classification of plant tanning agents and their role in leather dressing as well as a characteristic of tanning extracts. Further topics include moellens used for dressing old leather and a number of recipes for the production of assorted mixtures. Finally, the authors describe in detail the principles of the additional tanning of leather book bindings and dressing with emulsions and solvents.

Archeological leather objects discovered in water and soil call for suitable protection immediately after excavation. The Department of Paper and Leather Conservation at the Institute of Historical Monuments and Conservation in the Mikołaj Kopernik University has recently undertaken research on methods for the conservation of archeological leather. This procedure is composed of the following stages — mechanical and chemical cleaning which consists of the removal of dirt from the surface and inner structure of the leather, followed by the removal of tanine elements. Excellent effects were obtained by the application of the Sonorex Ultra Sound device combined with the use of the active surface Canpac and the EDTA Solution which causes blocking the above mentioned complexes responsible for the dark hues of the leather: - additional three-stage tanning combined with calcimine tanning - the introduction of lubricants or permeation with Si Finish WS 80 M silicone. The latter lowered the microbiological susceptibility of the treated leather.
