In the southern cave of Leigutai of the Longmen Grottoes, some Buddhist statues became seriously split. In order to protect these Buddhist statues effectively and to explore methods for consolidation of minute crevices, carboxymethyl cellulose was used to seal one of Buddhist statues which had become seriously split. The results showed that this method was not only useful for consolidation of statues with minute crevices, but also was simple, convenient and safe. It therefore is a feasible method for seal and protection in consolidation work.
