04-09. Silver #1.

From the mines of Potosi to the cathedrals of Spain – silver! Silver was a rare and precious material throughout the middle ages. It is also a mineral and the crystal of week #15 of this 52-weeks exploration of the geometry of Nature.

Silver is an element. It is also a crystal that belongs to the isometric-hexoctahedral system family – crystals that are made of 48 equal triangular faces.

All black and white, a very “minimalist” and regular symmetry, an interesting moiré pattern coming from the visualization of the Van der Waals force that defines the attraction field between molecules – Silver will be an unusual mineral to visually explore for a week.

This first image is coming from a resource by R. Wyckoff: structure of a silver crystal.
