Since the typical characteristics of crystals are often not sufficiently distinctive, the teaching takes place on models. Cardboard models illustrate the ideal external shape of a single crystal. They are dimensioned so that special features such as the shape of a surface, the size ratio of different surfaces or their respective position can be easily recognised – even from a distance of several metres.
