The whole process might be pretty long and can take several months, up to one year in special cases. Fraunhofer ISC has developed a rapid-screening systems during the last years, which is currently being optimized in collaboration with the BAM in Berlin. The robotic glass melting systems currently running in Berlin allows the melting of 20 samples during 24 hours and is backed up with high throughput RFA, LIBS and DSC devices for chemical composition, glass transition and crystallization characterization. As an additional option, the system can be extended with a robotic in-line characterization module for fundamental glass properties like viscosity, thermal expansion and crystallization behavior. Therefore, the method TOM - Thermo-Optical-Measurement method" was developed at Fraunhofer ISC to characterize physical and chemical parameter of glass. Recent advances include the preparation of larger samples with masses of up to 200 g, an optimized cooling process and a better batch as well as glass melt homogenization system. Further advancements of the system towards the development of glass-ceramics as well as enamel systems are discussed. References: [1] Scholze, H. Glass: Nature, Structure, and Properties. Springer.
