摘要：
Crystallization of a fluoride glass article is suppressed by treating the surface(s) of the fluoride glass article with a solution of a fluorine-containing alkali metal compound or a fluorine-containing ammonium compound such as, e.g., LiPF.sub.6, NaBF.sub.4 or NH.sub.4 BF.sub.4, in a nonaqueous solvent such as, e.g., ethanol, N,N-dimethylformamide or acetonitrile. The treatment can be made at room temperature.
