Conserving memories
Through deposition of sediment, fine clay, which
sank on the seafloor, the oilshale in the foreland
of the Swabian Alb was formed within 50 million
years.
It is about 180-200 million years old.
Due to its genesis, it contains a range of organic,
fossil and mineral substances and is thus very
healthful.
Earth and stone as materials represent – through
their attributes like smell, appearance and consistence -
a conjunction to homeland, roots and ancestry of humans.
At least a memory thereof.
