Cu + ⇌ R + (R = Li, Na, and K) ion exchange experiments were conducted for 20R 2 O·10Al 2 O 3 ·70SiO 2 glasses in molten CuCl at 550°C in air and nitrogen atmospheres. The depth profiles of the copper incorporated into glasses were determined with an electron microprobe X‐ray analyzer. The total amount of diffusing copper, M t , strongly depended on the type of alkali ion in the glass and the ion‐exchange atmosphere; i.e., M t increased with increasing cationic size in the order Li < Na < K and M t was greater in air than in nitrogen. The Cu ⇌ R + ion exchange kinetics are discussed in detail.
