Cleaning is an important step in the conservation and restoration of ancient ceramics, and the removal of hard attachments on the surface is a technical difficulty. However, ultrasonic cleaning, steam cleaning and chemical cleaning have technical limitations. In this work, sand-blasting cleaning was carried out on different surface attachments of ceramic samples to scientifically evaluate the safety performance and cleaning effectiveness of this cleaning technology. Color difference analysis and microscopy were used to test and evaluate the effects of sand-blasting cleaning on ceramic samples. The results show that sandblasting cleaning was safe for the cleaning of porcelains but had certain damage on potteries and overglaze colors. Comparative tests were also carried out to evaluate the effectiveness of sandblasting cleaning, ultrasonic cleaning and steam cleaning on the cleaning of several kinds surface attachments at different parts of porcelains, including the body, glaze, cross-section and crack. The effectiveness of sand-blasting cleaning was thus verified.
