Abstract
Washi, or Japanese paper, has been the most widely used documentary heritage restoration material in the West since 1960s. Currently, Japanese paper is marketed under the basics principlesof stability, compatibility and quality, although information on physical-mechanical, chemical properties and their long-term stability is not always available. Therefore, to improve washi knowledge, this study aims to characterize the physical-mechanical, chemical and fibrous properties of four papers commonly used in paper restoration: Sekishu Thin, Kozo Natur, Kuranai and Ohban Bunkamisu. As well as the effect of the application of these as a manual lamination treatment, in two cartographic documents (make by mechanical and chemical pulp) with serious acidity problems, dated in 1924 and 1898 each one. The study determined the grammage, pH value, mineral matter content, tensile strength and elongation, and optical properties of each paper and lining documents with washi, before and after accelerated aging to evaluate the stability of the treatment.
