 The microstructure especially, with its composition of densely packed fibrous crystals in a felted mass formation, contributed to the mineral's toughness and difficulty in carving.Due to this toughness and unique manufacturing techniques, the jade objects studied suggest an organized labor structure consisting of skilled laborers and an education in the handling of particular tools.Likewise, stylistic features and carving techniques seen throughout different Chinese cultures suggest a fluid transmission of knowledge between cultures rather than a border-bounded knowledge isolating cultures.
