利用裂解-气相色谱/质谱（Py-GC/MS）分析了琉球国木木寺墓中发现的一具木棺中的3块木片，并利用多接收电感耦合等离子体质谱（ICP-MS）测定了其中一块木片的87 Sr/86 Sr同位素比值，以确定漆器的制作材料及其产地。衍生Py-GC/MS分析结果表明，该生漆是由东亚产漆树（Toxicodendron vernicifluum）和东南亚产漆树（Toxicodendron succedaneum）的汁液中提取的。其中一个被认为是木棺剥离件的大碎片的膜层和木基的87 Sr/86 Sr同位素比值<0.710。然而，膜层的Sr浓度为35.0ppm，显著高于生漆汁液。这是可能的，Sr同位素比值的膜层反映了截面分析观察到的黑色颜料。从两块碎片的87 Sr/86 Sr比值来看，这幅漆画很可能是在有黑颜料和木材的地方完成的。木棺很可能是在日本的主要岛屿上建造的。同时，发现一块漆有漆树的木片，表明琉球王国与周边国家有着多种贸易关系。
Three wood chips found in a wooden coffin discovered in the Mumujyana graves of the Ryukyu Kingdom period were analyzed by pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS), and the87Sr/86Sr isotope ratio of one piece was measured by multi-collector inductively coupled plasma mass spectrometry to determine the materials used to produce the lacquerware and their provenance. Results from the derivative Py-GC/MS indicate that the lacquer was produced from sap of bothToxicodendron vernicifluum, which grows in eastern Asia, andToxicodendron succedaneum, which grows in southeastern Asia. The87Sr/86Sr isotope ratios of the film layer and wooden base of one large chip, which is considered to be a stripped piece of the wooden coffin, were <0.710. The Sr concentration of the film layer, however, was 35.0 ppm, significantly higher than that of raw lacquer sap. It is possible that the Sr isotope ratios of the film layer reflect that of a black pigment observed by cross-section analysis. From the87Sr/86Sr ratios of two parts of the chip, it is likely that the lacquer painting was done where the black pigment and wood were available. It is likely that the wooden coffin was constructed on the main islands of Japan. Meanwhile, the presence of a chip lacquered withToxicodendron succedaneumdemonstrates that the Ryukyu Kingdom had diverse trade relationships with surrounding countries.
