This jar is flattened and rounded in form, with a bulging belly and a constricted neck, and is fitted with a matching, flattened, round lid featuring an inner tongue-and-groove structure. The vessel walls are extremely thin, and the entire jar is transparent green in color, crystal-clear and jade-like, with an elegant form. It was used by aristocrats for storing spices. This glass vessel was produced using Western techniques introduced during the Wei and Jin periods. Unlike traditional lead glass with relatively low transparency, this new technology incorporated higher sodium and calcium content, greatly enhancing the vessel's transparency and malleability.
