The recrystallization in glasses presents a crucial characteristic for the procedure of melting processes as an inconvenient temperature performance can trigger off crystallizations interfering in production process.
Consequently knowledge about the temperature ranges preferred for recrystallizations is absolutely necessary.
In this analysis a glass sample is heated in a gradient furnace over a longer period of time so that crystallizations can be formed in a temperature-dependent way.
After that the sample is analyzed microscopically, crystal phases are determined and characteristic temperatures are registered (see also liquidus temperature).
