The study presents a visualization of the sequence of formation of eutectic grains during solidification in volume and directional solidification of model organic materials from the system of salol (faceted phase) - camphor (non-faceted phase) and carbon tetrabromide (non-faceted phase) - hexachloroethane (non-faceted phase). It has been proved that the faceted phase may act as a substrate for nucleation of the non-faceted phase, while the non-faceted phase in a eutectic grain is of polycrystalline character. The directional solidification of non-faceted/non-faceted eutectic enabled disclosing various structural defects, while solidification in volume explained in what way the, so called, halo effect is formed.
