The kinetics of copper‐potassium ion exchange of potassium aluminosilicate glass have been investigated in molten CuCl at 550°C in air and nitrogen. The presence of oxygen dissolved in molten CuCl has a great effect on the Cu‐K ion‐exchange kinetics, i.e. ion exchange in nitrogen is controlled by the interdiffusion process of Cu + and K + in the glass, whereas ion exchange in air seems to be controlled by the Cu + →Cu 2+ oxidation reaction.
