Korosteleva K., Sizova A. Tibetan Birchbark Manuscripts in the Serindian Collection of the IOM, RAS: Restoration and Identification // Written Monuments of the Orient. Vol. 10, No. 1 (20), 2024, p. 29–61
The article presents the Tibetan birchbark manuscripts kept in the Serindian collection of the IOM, RAS. The five birchbark manuscripts exhibit common codicological and paleographic characteristics, and the texts within them demonstrate a functional congruence, primarily associated with the rituals of consecration and empowerment. The objective of the conservation efforts was to flatten the birchbark fragments to both identify and preserve the inscribed texts. The fragments were sufficiently moistened in the birch sap as a plasticizer instead of regular water, given that it is a natural substance inherent to birch bark. The birch sap for conservation was hand-harvested from an ecologically pristine area. The soaking process in warm birch sap softened the fragments, and they were also cleansed of surface impurities. Damaged areas of the birchbark fragments were reinforced using Japanese conservation paper. For subsequent use and preservation, the fragments were stored in envelopes made of high-quality Melinex polyester film. Owing to the restoration work, five Tibetan birchbark manuscripts were described and transliterated.
