A large quantity of wall paintings from Buddhist monasteries and cave temples, discovered in central Asia at the end of the 19th- and early 20th centuries during expeditions by Sir Aurel Stein, are kept at the British Museum. The conservation and mounting of this collection is shown in two case studies, namely two painting fragments from Dandan-Oilik (782-787) and one painting from Ming-Oi (8th or 9th century). This text provides information on the paintings' provenance, method of construction and decoration, iconographical content, condition when entering the collection, and storage method. Their treatment made use of cleaning poultices in equal volumes of acetone and industrial methylated spirits (IMS). The acrylic silane mixture Raccanello E 55050 gave best consolidation results for both Dandan-Oilik fragments; the composition and technique of application of the reattachment paste are described as well as the storage containers adopted. The same informative details are provided concerning the treatment of the Ming-Oi painting, with emphasis on the steps taken for realignment and consolidation.
