Abstract Experimental work carried out by Jena University Observatory in collaboration with chemical institutions has shown that pyroxene glasses are very promising candidates for identifying silicate grains in the surroundings of very young objects in molecular clouds, e.g. BN objects and T Tauri stars. The experiments are of importance for gaining optical data that are needed for establishing source models and for understanding the mineralogical status of the grain material. In this paper, steps gone toward both goals in recent work of the Jena dust group are reported.
