Briefly compares Oriental and Western lacquer in terms of their chemical composition, materials and methods of manufacture, care and handling, and how these factors influence strength and durability of the object. Discusses special environmental requirements of Oriental lacquer and steps to take to preserve and protect it in the West, including humidification of rooms and cases, limiting light, avoiding washing and oiling of surface. Notes how cracks in the lacquer, often hidden by repairs which have discolored, are a sign of structural weakness in the wooden support. -- AATA
