All our shells are 100% natural products. Seashells and
freshwater shells are produced by animals as a protection
against the environment. When the animal leaves the shell, the
empty shell is washed to the shore, where it is collected. We
combine the shells with lights to highlight the form, the
structure, natural colors and materials.
Shells are made of calcite and aragonite. The materials are
combined in a way that it inhibits transverse crack propagation
and makes shells very strong and resilient with a Young's
modulus of 70 GPa . Most shells are made of three layers: 1) The
outermost layer of the shell is a colorful material called
periostracum is a thin organic coating or "skin" of the shell.
2) The
prismatic layer in
the middle.
3) The innermost layer of some
shells is nacre (also known as mother of pearl).
Nacre is very strong and iridescent. (Iridescent means that the
object appear to change color as the angle of view or the angle
of illumination changes. (soap bubbles are another example for
this phenomenon). The iridescent and transparent features of
nacre makes it very interesting for decoration and lighting.

The iridescent nacre (also known as mother of
pearl) is visible. |
When the light source is bright, the inner structure of the
nacre is visible. The light from the lamp is warm white color. |
