In this paper, the mechanism of the change of saturate colour of photochromic grey glass has been studied. It was suggested that the rechange of the (AgX)n colloid grain is the direct reason for the change of the saturate colour. The reason that causes the rechange of the (AgX)n colloid grain has also been analysed. Through controlling the heat-treatment condition and the content of Cu0 in glass, suggested measures that control the final saturate colour of photochromic grey glass are listed.
