Glasses with the base composition 8 BaO·8 SrO·34 ZnO·50 SiO₂ were studied with respect to the crystallization of a phase with the composition Ba_0.5Sr_0.5Zn₂Si₂O₇. Some glasses were doped with gold and/or antimony oxide. All glasses exhibited solely surface crystallization. If the glasses contained both antimony and gold, they showed red coloration after different heat treatments and the crystal growth velocities were enhanced, depending on the chosen temperature, by around a factor of 30. Crystals were proven to be oriented statistically, while in all other glasses of the system under consideration, i.e., in those which did not contain both gold and antimony, an orientation of the crystals with their c-axes perpendicular to the surface was obtained. This effect is explained by a continuous nucleation in front of the growing crystals.

对于组成为Ba _0.5 Sr _0.5 Zn ₂ Si ₂ O ₇的相的结晶，研究了基本成分为8 BaO·8 SrO·34 ZnO·50 SiO _2的玻璃。。一些玻璃掺有金和/或氧化锑。所有玻璃仅表现出表面结晶。如果玻璃中同时含有锑和金，则在经过不同的热处理后，它们会呈现红色，根据选择的温度，晶体的生长速度可提高约30倍。事实证明，晶体在统计学上是定向的，而在其他所有晶体中所考虑的系统的玻璃，即在不同时含有金和锑的玻璃中，获得了其c轴垂直于表面的晶体取向。这种作用可以通过生长晶体前面的连续成核来解释。
