Cleaning is a very important step in the restoration of cultural relics. Pottery material is fairly loose. It is a big challenge to clean early excavated potteries having complicated burial environments. Black stains were found all over a Han Dynasty female polychrome pottery figurine, seriously reducing its aesthetic value. After a survey of the object’s condition, traditional cleaning methods were tried, but the results were not satisfying. Laser cleaning techniques were then tried on different areas of the pottery figurine. The LQS mode was chosen with an energy of 150mJ, a frequency of 3Hz, and a spot size of 3~4mm. In some areas cleaning was effective, but in other areas it was not. The different effects were due to the relationship between the black stains and the base of the object, as well as the the energy of the laser. Laser cleaning turned out to be useful for potteries in certain cases, and could be used with other cleaning methods to achieve optimal results.
