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 [micro]m to 25 [micro]m across. When the grains were heated to between 60[degree]C and 80[degree]C 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.
