The study recommends new measures to better preserve such artifacts. One, for instance, involves use of an “air curtain” that would blow across the space to separate the figurines in the Qin Museum from the outside environment. The air curtains would keep pollutants and heat away from the inside of the pits. A layer of cool air would also be used in the bottom of the pits to help form a blanket of stagnant air around the relics for protection from the environment.
