ABSTRACT

Two artefacts in royal custody, an étagère (inventory number HGK401) and a writing desk (inventory number HGK1249), that display specific aspects of Swedish Rococo furniture in an exciting combination, are re-examined through scientific means. Microscopy of cross sections, wood species identification, scanning electron microscopy with energy dispersive X-ray spectroscopy, X-ray fluorescence microscopy, and pyrolysis-gas chromatography-mass spectrometry analyses reveal some of their physical and chemical characteristics. The results show that the original wood includes hinoki, and the actual urushi ware originates from at least two different artefacts, of which one was made in Japan. A specific mixture of saps hitherto only confirmed on historical Ryukyu Island urushi artefacts was detected. Blue coloured urushi is verified.

摘要

通过科学方法重新审查了两件皇家保管的文物，即étagère（库存号HGK401）和写字台（库存号HGK1249），它们以令人兴奋的组合展示了瑞典洛可可式家具的特定方面。横截面显微镜，木材种类鉴定，带能量色散X射线光谱的扫描电子显微镜，X射线荧光显微镜和热解-气相色谱-质谱分析揭示了它们的一些物理和化学特征。结果表明，原材包括丝柏，实际泽漆器皿至少来自两种不同的人工制品，其中一种是在日本制造的。迄今仅在历史悠久的琉球岛urushi人工制品上确认的特定汁液混合物被检测到。已验证蓝色urushi。
