印石,是中国印章的重要物质载体。在元代之前,人们多是采用金、银、铜、铁、玉、象牙等做为印章的材料。因为这些用材质地坚硬,只能由专业匠人刻制,这在很大程度上制约了中国印章艺术的发展。一直到了元代,一些文人书画家尝试用花乳石刻印,这个革命性的创举,宣告了石质印章时代的到来。 India stone, is an important material carrier of China’s seal. Before the Yuan Dynasty, most people used gold, silver, copper, iron, jade, ivory and other materials as seals. Because these materials are hard, can only be engraved by professional craftsmen, which to a large extent restricted the development of Chinese seal art. It was not until the Yuan Dynasty that some writers of calligraphers attempted to engrave flowers with flowers of milk stone. This revolutionary initiative proclaimed the arrival of the era of stone seals.
