中文摘要：为研究汉代髹漆工艺中是否含有淀粉粘结剂,利用淀粉粒分析方法提取了长沙风篷岭汉墓出土的漆器残片中的残留物。实验结果显示:在偏光显微镜下观察到具有十字消光特性的淀粉颗粒,粒度大小在13至25μm,且有加热糊化的现象,加热温度在60至80℃,加热时间大约在30min以内本实验证实在汉代漆器制作过程中使用了淀粉作为粘结剂,为研究汉代漆器的制作工艺提供了新的科学方法

英文摘要：Starch grains analysis was used to study the residues of lacquer binder in lacquer fragments excavated from the Fengpengling site,Changsha.Starch grains possessing a distinctive Maltese cross effect were observed using a polarizing microscope.The grain size ranged from 13 am to 25 am across.When the grains were heated to between 60℃and 80℃for about 30 min,the grains showed gelatinization.These results indicate that starch was mixed into the binder during production of the lacquer pieces.This research provides a new method for studying the Han Dynasty lacquer craftsmanship.
