Black Lacquered Papier-mâché and Turned Wooden Furniture: Unravelling the Art History, Technology and Chemistry of the 19th-Century Japanning Industry

A set of 19th-century furniture in black lacquer, on papier-mache or on turned wood, has been subjected to an in-depth observational, historical and chemical study. The results show four different technological approaches: two for the papier-mache objects and two for the wooden chairs. The cyclic labour-intensive lacquering procedure of repeated stoving and polishing lacquer on papier-mache with mother-of-pearl inclusions is reflected in the cross-sections. Pinaceae resin and heated oil are frequently found, conform with surviving recipes. A variant of the old form of varnish', as historically described, was likely used. In the two pairs of wooden chairs, the lacquer layers are thinner than on the papier-mache items. They contain copal and show different stratigraphies. These observations can be the starting point to relate technological and chemical variations to different origins. New art historical findings on lacquer production and trade in England, France and Belgium, and the study of contemporary recipes, frame the analytical results in a historical context. [GRAPHICS] .
