Matched copies of the book Cooking the Greek Way, which had been printed in Czechoslovakia on acidic paper, were evaluated. Nonaqueous treatment of two of the copies with magnesium methoxide dissolved in chlorofluorocarbon solvent had been found in 1967 to have decreased the susceptibility to embrittlement, as evidenced by the results of the accelerated aging, followed by folding endurance tests. Retesting of the same books in 2019, after 52 years of room temperature storage, showed that the deacidification treatments had achieved the following benefits in comparison to the untreated book: (a) higher brightness; (b) higher folding endurance; (c) tensile breaking length higher in the cross-direction of the paper; (d) substantial alkaline reserve content, (e) an alkaline surface pH in the range 7.1–7.4, and (f) higher molecular mass of the cellulose. Remarkably, some of the folding endurance results matched those of unaged samples evaluated in 1967. Scanning electron micrographs showed no differences between the treated and untreated books.","PeriodicalId":21154,"journal":{"name":"Restaurator.

The pH at the edges of the alkaline paper lowered from 7.5 to 6.4 after 5–10 years and to 5.8 after 10–15 years after publication. The pH bottomed at 5.4 at the edges and at 7.0 in the centre of the sheet. Acid paper showed higher pH at the edges than in the centre of the sheet. The edge pH of the alkaline paper of books stored on an above-ground floor was lower due to more exposure to incoming open air with pollutants compared to paper stored in the basement. Elemental analysis suggested nitrogen oxide deposition, but could not prove sulphur oxide deposition at the edges of the paper. The position-dependent acidification is presumed to relate to the deposition tendency of air pollutants contained in open air, and accordingly the edge pH dropped dramatically. In the 1980s, alkaline paper was increasingly used in the production of books, and it was assumed that no more book acidification was to occur; however, this study concludes that even in alkaline paper, acidification processes will take place over time.","PeriodicalId":21154,"journal":{"name":"Restaurator.

Four VOCs sorption materials were tested for their ability to eliminate HP gas evolving from the treated substrate. This was tested by measuring the change in HP concentration in aqueous solution and in an enclosed air space in the presence of MicroChamber® Interleaving Paper, Corrosion Intercept® film, Zorflex® activated carbon cloth (ACC) and iron sulphate-impregnated paper. Detection with the colour indicator Quantofix® test strips and a Dräger X-am® 5100 single gas detection device showed that ACC is by far most efficient in decreasing the HP concentration. ACC was also effective in preventing paper discolouration in test objects that had been HP-treated for lead white conversion and then were stored sandwiched between ACC. Although ACC may not eliminate all HP from the substrate, it can diminish its negative effects on the treated object and protect other objects in the vicinity.","PeriodicalId":21154,"journal":{"name":"Restaurator.

A possible solution to this problem lies in labelling these documents with codes that are invisible to the naked eye. A possible method could involve use, e.g. of the oxides of lanthanum, dysprosium, samarium, gadolinium and niobium, which have good responses in the XRF spectrum and are normally not present in archival materials. This study is concerned with the impact of these oxides on the properties of lignocellulosic materials. The identification tags were printed on three different kinds of paper supports (Whatman No. 1 filter paper, paper according to ISO 9706 and sulphite pulp). The colour change, average degree of polymerisation, the pH values of an aqueous extract and selected mechanical properties after application of the tag and artificial ageing were studied on all the samples. The measurements showed that the studied oxides do not have a negative effect on the monitored properties of the paper supports and do not affect their long-term ageing behaviour.","PeriodicalId":21154,"journal":{"name":"Restaurator.

Four Chinese handmade papers, Yingchun, Zhuma, Yuanshu and Longxucao papers were used as model substrates of mulberry bark, ramie, bamboo and Eulaliopsis binata papers, respectively. Two forms of the paper samples, paper sheets and their comminuted powders, were used in this study. The results showed that their XRD patterns belong to the cellulose-I type and Iβ dominates the cellulose microstructure of these paper samples. Moreover, it was found that the microstructures and CrIs of cellulose of these papers were changed by the grinding treatment. This work suggested that the sheet form of the handmade papers is suitable to determine CrI by XRD, despite the contribution of non-cellulosic components in the papers. The order of CrIs for these paper sheet samples was Yingchun, Zhuma, Longxucao and Yuanshu papers. Besides CrIs, differences in cross-sectional areas of the crystalline zone of cellulose can be used for comparing different types of handmade papers. It was also found that the CrIs and crystallite size of paper cellulose varied between the sheet samples and the powder samples, illustrating that the pulverisation has a negative influence on the microstructure of the handmade papers.","PeriodicalId":21154,"journal":{"name":"Restaurator.

Our words may reach you at home, during quarantine, at your workplace which may have changed, or at your studio with fewer projects as planned in your order book. We do hope that you stay healthy and that your professional prospects have not worsened considerably. Securities which we have taken for granted have suddenly vanished and our perspectives have shifted. However, one realization seems to prove true more than ever before: the importance of scientific research. We clearly see that it is not only essential to conduct research, but to also share research results and to base decisions on the outcome of transparent studies. In this respect, we want to thank our authors, reviewers and our board for making this publication possible – even during times of constraints and instability. Those of you who have visited our journal homepage will have noticed that the design of the page has changed. We think that searching the homepage has become more convenient and while currently, it is still partly under construction with new changes and guideline upcoming, we hope that you enjoy our new homepage as well! It is always worth visiting because in each issue there is one open access contribution, carefully selected to highlight research results published in RESTAURATOR. The current issue features contributions that had to wait for being printed a bit longer than usual due to our last year’s thematic issue on the history in conservation and teaching. The topics of the current issue range from a technical note on improving paper stability after converting blackened lead white with hydrogen peroxide by Raab et al. to a novel labelling technique to proof ownership by Krejčí et al. and to an analytical study to research the crystallinity of various handmade Chinese papers as a fundament to evaluate the crystallinity’s role in durability of paper.","PeriodicalId":21154,"journal":{"name":"Restaurator.
