Appreciations of anitiquities are generally based not only on uniqueness and qualities but also on the additional change of their original forms through time and circumstances. Even fading and spalling sometime gives special impression on anitiquities. In the present paper falling behaviours of dust on the antiquities are focused and investigated together with considering their rolling up motions. It is found that even though velocities of falling dust are estimated as well bellow as several centimeters per seconds, high strain rate deformation well over several hundred per sec may be associated in the events. Fading and spalling on the anitiquities seems to proceed steadily over several hundreds of years, but impact mechanics might be involved as elemental processes.
