Definition Of

Textiles made of organic fibers, include anthropologic knowledge about lifestyle, art idea, mythology, daily life and religious traditions of the culture made them. These tangible examples of Cultural identity of the society important for transfer traditional knowledge from next generation. Textile Cultural artefacts responsibility and interest of conservation and restoration science professionals can find from archaeological excavations or gathering from urban areas and given to museums from collectors. Historic textiles are hard to found well preserved and hard to passing it onto the next generation compared to artefacts made from inorganic materials because of they made of organic materials. Every country on the earth has their own definition of Cultural Heritage and preservation laws. Under this diversity in the field of conservation and restoration science, it is necessary to establish standard definitions and use a common language at academic field likewise in every profession. Ethical codes and principles made for conservation of Cultural Heritage are a guide for conservation professionals. Politics of conservation practices change by technology development. In recent years, by analytical research, has been noticed that active conservation activities can damage the cultural heritage hence passive conservation activities like documentation and preservative conservation becomes priority. Descriptive scanning model based on screening of literature related to textile conservation was adopted for this paper.

AbstractCultural heritage objects composed of inorganic materials, such as metals and stones, support microbial life. Many factors affect the growth of microorganisms: moisture, pH, light, temperature, nutrients. Their colonization relates closely to the nature of the substrata as well as to the characteristic of the surrounding environment. This chapter contains an overview of the complex relationships among microbial growth, materials, and the environment. It emphasizes issues on bioreceptivity of stones and the factors influencing biological colonization, focusing on the biological alteration of inorganic heritage objects and on the agents of biodeterioration. It outlines the effect of biofilms and lichens in terms of degradation of substrata and includes a discussion on an important topic, the bioprotection of stones by biofilms and lichens. In summary, this chapter aims to discuss these issues and review the recent literature on (i) biofilms and lichens colonizing inorganic materials, (ii) the limiting factors of this colonization, (iii) the deteriorative aspects, and (iv) the protective effects of the colonization.

A specific European standardisation activity in the field of conservation of cultural heritage is essential to acquire a common unified scientific approach to the problems relevant to the preservation and conservation of the cultural property. The scope of CEN TC 346 is to establish standards in the field of the processes, practices, methodologies and documentation of conservation of tangible cultural heritage to support its preservation, protection and maintenance and to enhance its significance. This includes standardisation on the characterisation of deterioration processes and environmental conditions for cultural heritage and the products and technologies used for the planning and execution of conservation, restoration, repair and maintenance.  Up to now sixteen EN standards were published according to a matrix-based method in which three main topics have been developed. First is dealing with general guidelines and methodology. Second topic is regarding Evaluation of methods and products for conservation works. The work was focused on a general draft “Surface protection for porous inorganic materials-laboratory test methods for the evaluation of the performance of water repellent products”. The evaluation is based on the measurements of different parameters appropriate to assess the performance of the product using standardized and reproducible methods. Third topic is regarding Indoor/outdoor climate-Specifications and measurement. The purpose of the work was to develop standards and recommendations relating specifically to the climate and its influence on the preservation of heritage. Standards developed will assist professionals involved in environmental diagnostics and in the investigation and control of the climate for preventive conservation and maintenance. The assistance includes the choice of methodologies and instruments and the interpretation of results.
