Lacquerwork technologies comprise multiple techniques depending on countries, time, and traditions. Carved Asian lacquers applied on wooden objects consist of multiple thin uncolored or pigmented layers spread over the surface. To radiocarbon (14C) date these types of objects, often only the wooden structure is used. Here we report on a set of carved lacquered objects that were dated based on stylistic form, 14C dating of the wooden structure and of the Asian lacquers. THM-Py-GC-MS and micro-Raman spectroscopy were used to confirm the molecular composition of the lacquers and helped assessing the pretreatment protocol. The lacquers analyzed contained between 20 and 50% wt carbon, thus 2–5 mg of sample were necessary for 14C dating. The dates obtained on wood and lacquers showed a reliable correlation. The results suggest that, in most cases, it is sufficient to sample a part of the lacquer layers to date an object. We advise to perform an acid pretreatment followed by a successive solvent immersion with an increasing polarity. Dating different components of a lacquered object can also help to understand previous restoration interventions that frequently occur for ancient lacquered objects. Ceramic, metallic, and other objects covered with Asian lacquers can also be dated using this approach.

漆器技术包含多种技术，具体取决于国家、时间和传统。应用于木制物品上的亚洲雕刻漆由覆盖在表面上的多个薄薄的无色或着色层组成。为了对这些类型的物体进行放射性碳（14 C）测年，通常只使用木结构。在这里，我们报告了一组根据风格形式、木质结构和亚洲漆器的14 C 年代测定的雕刻漆器。THM-Py-GC-MS 和显微拉曼光谱用于确认漆的分子组成，并帮助评估预处理方案。所分析的漆含有 20% 至 50% wt 的碳，因此14 C 测年需要 2-5 mg 的样品。在木头和漆上获得的日期显示出可靠的相关性。结果表明，在大多数情况下，对部分漆层进行采样就足以确定物体的年代。我们建议先进行酸预处理，然后进行极性逐渐增加的连续溶剂浸泡。对漆器的不同组成部分进行年代测定也有助于了解以前对古代漆器经常发生的修复干预措施。陶瓷、金属和其他覆盖有亚洲漆的物体也可以使用这种方法来确定年代。
