The dissolving phenomenon of SiO_2-La_2O_3(CeO_2)-K_2O system glasses were studied in this paper. The fused glasses were powdered into particles of 35-60 meshes and lg of them were immersed in 50cc water of 303,323 and 343 K and agitated for 10,20,40 and 80 min.. Then the amount af K ion dissolved in water was measured by 0.1 or 0.01 N HCl. The results were as follows. (1) Log of amount of K ion dissolved in water was linear function of log of dissolving time and the reciprocal of dissolving temperature. (2) The amount of K ion dissolved in water depended on the concentration of SiO_2,rather than the concentration of K_2O. (3) The amount of K ion dissolved in water was more than the amount of Na ion and Li ion on same conditions.
