Nucleation rates were measured in a ZrF{sub 4}-BaF{sub 2}-NaF-LaF{sub 3}-AlF{sub 3} glass (ZBLAN) using an optical technique. The results were compared with a similar glass having a slightly different composition. The difference in the nucleation rate is explained by classical nucleation theory using calculated free-energy differences between the ZBLAN liquid and the BaZrF{sub 6} crystal, which is found as the precipitating phase.
