在山东新泰周家庄东周时期的一墓葬中，出土了一把具有吴国兵器特征的青铜剑，在该剑的剑格内，发现了一薄层用于镶嵌固定各种形状绿松石的白色物质。为分析此物质，经傅立叶变换红外光谱（FTIR）分析表明，该白色物是一种具有饱和脂肪酸酯类结构和羧酸结构的混合物，与多种关然胶粘剂的标准红外光谱进行比较，结果显示样品的红外谱图与虫胶（漆片）的匹配度最高。同时用附带有能谱仪的扫描电镜（SEM-EDS）分析了该样品，结果表明样品不含元素氮，因而可排除蛋白质胶和生漆类等含氮的天然胶粘剂。

On a bronze sword excavated form East Zhou tombs in Zhoujiazhuang （Zhou Family Village）, Shandong province; it was found that a thin layer of white substance had been used to glue turquoises of all shapes to the sword cross-guard. A FTIR spectrum showed that the sample contained saturated esters and carboxylic acids. In comparison with standard FTIR spectra of many natural adhesives, the FTIR spectrum of the sample matched best that of shellac. SEM - EDS results showed that sample did not contain nitrogen, so nitrogenous adhesives such as protein glues and lacquer would not be the source.
