A rare Italian teaching set of 8 glass models, representing the different shapes of the mineral crystals, ca. 1930’s.
Internal silk threads materialize the crystallographic axes, in different colours. Cube side length 12,5 cm (as reference for measures), a couple of airlines in 2 sides of the cube (but stable) and a broken red thread in 1 model, otherwise in great condition.
Most of them still have traces of the paper label for their inventory (that of course can be easily removed).

Established in 2005 in Italy, Nautilus tries to be a modern wunderkammer, where antique science and natural history meet, inspiring wonder. I mainly love antique scientific and medical instruments, but my interest extends to unusual or rare technologies and natural history.
