Opis:
The Romanesque doorway from Ołbin whose origins may be dated as early back as to the late 12-th century was built from blocks of arkose sandstone. During the long course of history its state of preservation gradually deteriorated and thus it had many times to be subjected to conservating treatments. Its surface was, among the others, reinforced by means of liquid glass and chemicals of the fluosilicate group. It seems, however, that the treatments applied did not bring intended effects and this probably was the reason why one part of the doorway has been coated with cement milk whereas the others co-ered with a protective layer of a hardly distinguishable polymer-type organic matter. Nevertheless, these superficial coatings have proved to be unable to prevent advancing decay and the stones were getting more and more disintegrated, maybe at even higher rate as it was the case at earlier date. Finally, the layers next to the stone surface begun to split and exfoliate and from underneath poured the powdered sandstone. This increasing decay has led to substantial decrements in the total mass and also to deformations in the plastic appearance of the doorway. In effect of investigations carried out it became possible to find that these destructions were, in the first line, caused by the action of water-soluble salts and water penetrating into the doorway from the church interior which the both occurrences were due to the fact that the outer surfaces of walls have been faced with clinker bricks hardly permeable for water. Although several expert bodies were meeting with this object in mind no clearly outlined programme of preservation works for the said doorway has been worked out in conclusion. The works carried out within the first stage comprised the following measures: encasing of the doorway to protect it against the immediate weather influences (mainly the waters'), securing the fragments by glueing the paper on their surfaces, removing the clinker bricks from the immediate neighbourhood of the doorway, and, finally, building of a cellar under it to stop the flow of ground waters. The undertaking of a full-scale treatment has become possible only on completion of examination of possibilities to apply epoxy resin solutions for structural impregnation and also on working out of the s.c. pocket-type method for stone saturation. Investigations in this respect were conducted at the Copernicus University, Toruń to order of the Historical Monuments Documentation Centre, Warsaw. The conservating works themselves were carried on in the years 1967 and 1968 and their plan covered the actions named below: a) superficial strengthening of pouring, delaminating and exfoliating portions of stones from which the doorway is built, . b) reinforcement of the breaking away fragments of doorway with the application of putties and fillings, c) removing of the superficial built-up layers with the aim to restore the stone porosity and ipso facto enable the impregnation, d) removing the cement and gypsum putties and fillings by means of which the former decrements in stones were filled up, e) extraction of water-soluble salts, f) structural impregnation of the entire doorway with the aim to reinforce the deepest stone layers, g) filling with putties the holes and pin cracks. The superficial reinforcing of stones was carried out by means of the 20 per cent methylbenzene solution of epoxy resin. The resin was hardened by treating it with triethylenetetraamine. For reinforcing of stone fragments that have broken and exfoliated thus threatening to flake the putty has been applied obtained by mixing the epoxy resin with powdered sandstone in 1 : 15 proportion. The putty was filled into pin cracks and then pressed. With the putties hardened a durable junction was obtained between the loose fragments and their bed. Thanks to the properties possessed by existing built-up layers they could be removed with the use of either chemical or mechanical means. Chemically were removed the layers formed in result of an usual action exerted by atmospheric components, and the 3 to 6 per cent hydrofluoric acid was applied for this purpose. Portions on which the afore-mentioned built-up layers have been found comprised well under 10 per cent of the total doorway area. The layers consisting of cements and organic matter not soluble in solvents available were removed mechanically by means of scrapers. With the dark-coloured built-up layers removed the stones of which the doorway is composed have regained their original colour, texture and plasticity. (However, it has proved impossible to restore to the superficial stone layers their original porosity. The reinforcing substances with which the stone pores were filled are unremovable and their porosity could be restored only by means of grinding-off the superficial layers being, of course, an inadmissible practice. The cement putties and some gypsum putties, too, applied during the former restorations of the doorway were removed, for they contributed to the accelerated destruction of stones, in addition forming black spots on the brighter coloured background. On completion of the above-mentioned works the next stage has been started, consisting in removing of water-soluble salts. A method of their forced migration to paper layer was applied using the fivefold coating of the entire doorway with water saturated paper sheets. Already the fourth consecutive paper coating did not reveal the presence of salt. The above method allowed to remove the salts from pores next to the stone surface which the fact is due to limited permeability of water into the deeper stone layers in effect of earlier applied treatments (N. B. migration of salts occurs only in parts saturated with water). As the superficial impregnation of doorway carried out by means of epoxy resin solution is able to prevent decay for a limited period of time only it has been decided to reinforce the structure of the doorway stones in their deepest possible layers (structural impregnation). This treatment was carried out using 10 per cent toluene-and-methyl alcohol solution of epoxy resin in the respective proportion of 1 : 2 and 1 : 3. The amount of methyl alcohol present in 'Solution was deciding for the rate of resin precipitation from it. At the 1 : 2 proportion the precipitation was beginning after about 20 hours whereas at 1 : 3 after about l'O hours. The first of the above solutions was applied in cases in which the need occurred to saturate the stones for more than 12 hours, the other one — for saturation periods not reaching the time given above. Solutions were prepared in portions of 1 to 4 litres to which 15 per cent of triethylenetetraamine was added in proportion to resin amount. They were introduced into the doorway stones by means of s.c. pooket-type method. The pockets were prepared in such a way that on the stone surface were put 5 to 6 layers of the water-saturated paper onto which, starting from their edges, the gypsum mortar was imposed forming the 1 to 2 cms wide framing at all sides. In the upper parts of so formed lining a filler was made from a piece of paper and the whole covered with gypsum . The separate stages of the pocket-forming may easily be seen from illustrations. All the elements of doorway were covered with pockets. With the gypsum mortar dried the tightness of pockets was examined by means of solvents and leakages removed. The impregnation has been carried out by pouring the solution into pockets and its steady supplementing so that the pockets could be kept full throughout the entire period of saturation. During one-day operation were saturated the doorway elements with sizes allowing to complete saturation and removing the pockets themselves within 30 hours. It has been found that within this period the epoxy resin gel forming in gypsum pores was still thin enough to enable the easy removal of pockets. They could be removed without damaging the stones as the object after impregnation was secured with cellophane having inhibitory effect on evaporation of solvents. Since the rests of gypsum remained on the stone surfaces they had to be removed at once thus not permitting their hardening by the active resin. After cleaning operation the saturated elements were insulated by means of cellophane from the ambient atmosphere for a period of 10 to 14 days to allow the maximum rate of precipitation of resin from the solvent. Three hundred ninety litres of resin solution were used for this purpose of which the amount some 295 litres have been introduced into stone, the balance being absorbed by gypsum and lost during the operation. Within the last operation the supplementing of slight stone decrements in form of holes and pin cracks with the epoxy putties has been carried out. For this purpose, much the same as in the course of the above-described operation, a mixture composed of 1 part of epoxy resin and 15 parts powdered sandstone has been applied. To this mixture containing hardener (15 per cent) petroleum spirits were added to obtain better conditions for hardening. The putties prepared for this operation are characteristic of their higher degree of porosity at the same time showing good water-repellent properties and impact strength similar to that of actual stone. For preparing the putties the white sandstone powder was used so that after their hardening it proved necessary to patinate them together with traces left by pockets („crabs”) using mineral dyes with 1 per cent addition of epoxy resin solution acting as hardener. The illustrations show the doorway in state after preservation operations.

Opis:
The aim of the research was to examine the possibilities and ways of application of S. Z. Lewin’s method in limestone reinforcement. The method constists in limestone impregnation with the solution of carbamide and barium hydroxide. As a result of the chemical reaction in limestone pores the insoluble barium carbonate is precipitated; it is to play the function of the reinforcement. ' At the first stage of the research work the experiments, as described by S. Z. Lewin, were carried out. They dealt with the cementation of powdered chalk in reinforcing solution. Results of these experiments, however, proved to be a failure: after the six-month period of impregnation the cementation of limestone powder did not occur. The second stage consisted in extending the scope of the research. It included the influence of temperature and duration upon the processes of barium carbonate precipitation and limestone powder cementation as well as the effects of the duration of impregnating solution action on mechanical and physical properties of limestone. Moreover, derivatographic and X-ray structural analyses of impregnated limestone were made. As a consequence of the above experiments it was stated that the efficiency of the process of barium carbonate precipitation in room temperature was very small ((about 26 per cent after 30 days). It increases proportionally to the growth of temperature, being sufficient at 95°C. The increase of limestone strength was not stated on the grounds of influence of duration of the solution action (up to 3 months) in room temperature. Absorbing and capillary capacities of limestone, however, decreased and this proved the partial seal of limestone pores caused by barium carbonate. The application of barium hydroxide solution (free of carbamide) brought similar results. In the latter case the chemical reaction of barium hydroxide with calcium carbonate took place. The above-mentioned results were confirmed by X-ray structural investigations. It should be stressed that the cementation of limestone powder and chalk did not occur although hardening solutions of raised temperature (up to 95°C) were being used. Because of negative results of the tests carried out we cannot apply S. Z. Lewin’s method in limestone hardening. This method seems to be sufficient only for protecting the stone against the destructive components of atmosphere (chiefly S 0 2). There are two possible explanations of this situation: in his publications S. Z. Lewin did not make the conditions of limestone hardening clear enough or he might have used some additional substances which caused crystalline barium carbonate to emerge. Crystalline barium carbonate is capable of making crystalline concretions with calcite. In this case both the cementation of limestone powder and thereby reinforcing of limestone should occur.

Research aimed at elucidating the causes of m igrations of thermoplastic resins — employed as solutions for reinforcement of porous stones — has been taken up. Solutions of butyl polymethacrylate have been used for the purpose, the limestone from the region of Pińczów being saturated with them in the tests concerned. The impact exerted by the degree of polymerization of resins, solvents and concentration on capillary ascent o f solutions, the degree of saturation of the stcnes, their drying capacity and finally on the process of migration of resins in the course of drying has been studied. The results of the investigations have made it possible to determine the paramétrés chesking the process o f migration of butyl polymethacrylate to the surface of Pińczów limestone. As has been ascertained, the main cause deciding about the course of migration is viscosity of solutions. Its degree may be adjusted by way of employing polymers with a higher degree of polymerization or by enhancing concentration of the solutions. The first route has been recognized as more efefctive since it provides for multiple repetition of the proceeding by means of diluted solutions what is of great significance from the viewpoint of conservation practice. Now as regards the solvents used, the best results have been obtained in the case of white spirit. Due to the specific phenomena accompanying its evaporation, solutions with a low degree of viscosity may be applied and the effect of structural reinforcement duly achieved. If aromatic hydrocarbons used as solvents, the viscosity of the solutions should amount to 10+15 cP. On the grounds of the results obtained an attempt has been made at elucidation of the phenomena of migration what enables selection of adequate paramétrés providing for structural reinforcement of the monuments built, or made, of porous materials.

The methods of application — by Polish and Soviet research workers ■— of methyl-cellulose for strengthening old paper of historical value are described. The author’s own investigations aimed at determining the usefulness of various types of methylcellulose in conservation practice. The tests concerned were made with both new and impaired paper i.e. that subject to the process of artificial aging. Their results have shown that the applied kinds of methyl-cellulose exert a positive impact on enhancement of the strength of new paper and that subject to aging at 105°C. If the temperature of 165°C applied, the effects are less satisfactory. Good results have been obtained with Tylose C-300 and C-600 employed for the strengthening of impaired paper. Moreover, as has been ascertained, the said agents also have protective properties.

Opis:
For some time conservators have been propagating a new method of reinforcing historic stone objects by means of the so-called stable silica. According to the explanations of the author (Dr Bąkowski) the method consists in the saturation of the stone with water glass and with the addition of special catalysts which bring about a production of insoluble crystal silica in pores. This transformation exerts a major effect upon a mechanical strength and resistance to aging. In order to evaluate the proposed method objectively the reinforced samples have been studied in detail. During laboratory testings the following determinations have been made: the content of reinforcing substances and their distribution in the structure of samples, ability of capillary drawing-up of water and water absorption, mechanical strength, content of soluble salts in water and their ability to produce efflorescences and bring about a sample destruction. Studies have been made to examine resistance to frost. Additionally, crystal mircrostructures in reinforced limestone have also been investigated. The results of the studies made have shown : — only a slight increase in the sample mass as a result of the reinforcing (3.7% rise), — considerable sealing of surface pores, — a lower water absorption (by 25—30%). It should be pointed out that this kind of increased resistance might also be obtained by saturating the samples with water glass without catalysts. A slight effect of desalting and long drying-up upon a mechanical strength has also been noted. The examination of the distribution of a reinforcing substance in the structure of the samples has shown that it is uneven, mainly in the zone close to the surface. The content of soluble salts in water is considerable and came to 1.96 per cent. This quantity was made of sulphates, chlorides, nitrates and sodium carbonates. Of interest is the fact that the quantities were found out after a two-stage desalting done by the author of the proposed method. The studies made show that strengthening substances found in the examined samples consist of amorphous Si02, silicates and an unidentified crystal phase with a reflex of 4,46A. On the basis of the studies carried out it may be staled that the method proposed has not shown the advantages ascribed to it and so cannot be employed in practice in the conservation of stone historic objects.

Opis:
Nos 3 — 4 of the 1981 edition of “Ochrona Zabytkow” (pp. 172—180) contained an article by Ryszard Mirowski entitled “Properties of Pinczow Limestone Reinforced with a “Stable Silica” Technique”. The article quoted results of studies on samples of limestone hardened by means of the method recommended by Zdzisław Bąkowski. As can be seen form the publication, results obtained were negative. Finding the preservation of stone monuments an important problem, the author of the present article decided to give a few comments to accomplish the above-mentioned paper. Dr Z. Bąkowski elaborated a method to preserve stone by employing “stable silica” to sandstone monuments. The first objects on which the method was applied came from Faras, i.e. the Nubia sandstone was the subject of preservation. Positive results were obtained. Then objects from magma rocks were presered and also in that case the technique gave good results. Of utmost significance are results of the studies published by R. Mirowski confirming the fact that multi-directional mineralogical- petrographic studies must be made prior to the conservation of carbonate objects, which would allow for the use of various preservation techniques. This procedure has been employed by Dr Z. Bąkowski with a great ssuccess in the recent years.

Opis:
The author discusses two Japanese polysaccharides from the viewpoint of their application as the doubling binder for paintings on silk and silken fabrics — the non-gluten wheat starch shofu and the seaweed glue funori. Detailed research concerned the quality of the wheat starch. Subsequently, the author compared the properties of the two polysaccharides. Following studies concerned the rheology, resistance and rigidity of the binder as well as the artificial aging of samples of silk fabric and Japanese paper containing the glues in question. The aging of both natural binders was conducted in a climatic chamber for 24 days in a temperature of 65°C and with a humidity of 55% RH, as well as by means of exposure to a xenon lamp for 240 hours. The results indicated the extremely stable optical properties of the funori glue and its positive impact upon the resistance of silk. Research conducted with the aid of SEM (electronic scanning microscope) indicates the way in which the glue spreads on the surface of the fabric.
