摘要
文物清洗是文物修复中极为重要的一环。针对质地疏松、时代久远、埋藏环境较为复杂的出土陶器,表面清洗是一种较大的挑战。本次清洗的对象是馆藏的汉代彩绘女陶俑,陶俑身上遍布黑斑,严重影响了其观赏价值。为有效清除表面黑斑,尝试运用激光清洗技术进行清洗工作。确定采用LQS模式下,输出能量为150m J,频率为3Hz的系统光学参数,并选择光斑直径在3~4mm的范围,用激光垂直照射液膜法进行清洗。结果发现部分区域清洗效果较好,而部分区域清洗效果一般。造成不同效果的原因,主要在于黑色污染物与基底之间的关系以及激光能量的选择。实验结果证明,激光清洗陶器表面的黑斑是可行的,与此同时也可以结合不同的清洗方法来达到最佳的清洗效果。
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.
