Platonic solids are the five convex geometric solids (tetrahedron, hexahedron, octahedron, dodecahedron, icosahedron) that exhibit the greatest possible symmetry and whose faces consist of congruent, regular polygons - the triangle, the square or the pentagon. An equal number of edges of equal length meet at each corner of the solid, two congruent faces meet at each edge and each face has the same number of corners.

The dodecahedron above was made from precious metal and colored parchment for a private collection.

A model is sketched out at the kitchen table in order to get closer to the idea and identify possible difficulties in advance.

Using goldsmith craftsmanship, a frame is constructed from 925/- silver tubing
and hollow spheres. The challenge is to assemble and solder the tubes at
the right angle.

30 sides are each 50 mm long. The tube diameter is 4 mm, the diameter of each of the 20 balls is 6 mm. The device is now galvanised with fine gold plating.

After a series of colour samples, the roughly cut pieces of parchment are dyed according to the spectral colours.

The pentagons are folded to make them more precise and the holes for the seams are drilled.

Twelve pieces of parchment are first loosely attached to the scaffolding, field by field, with silk.

The stitch is tightened and knotted.

When light falls through the different coloured parchment fields, a different play of colours appears in every direction.
