Abstract(s)
Oriental lacquers have been used as coating
materials for thousands of years for wooden, ceramics,
leather and metal objects. Lacquers are natural polymers
obtained from three species growing in different regions of
Asia: Rhus vernicifera (China, Japan and Korea); Rhus
succedanea (Vietnam and Taiwan); and Melanorrhoea
usitate (Myanmar and Thailand). The identification of
lacquer films is important for conservation and restoration
purposes, as well as for art history studies because it may
help in determining the origin of the lacquered objects. In
this work, pyrolysis-gas chromatography/mass spectrometry
using a filament-type pyrolyser was successfully applied
to the characterization of oriental lacquers. A method to
identify the three kinds of lacquer was developed and
applied to the study of two lacquered shields imported from
Asia in the sixteenth century. The materials that constitute
the shields were also examined by Fourier-transform infrared microspectroscopy and details of the lacquering
technique are reported
