footprints for eternity
A natural stone is a real piece of the earth's 140-million-year-old surface. Traces of this early period were repeatedly covered in sand by storm surges over the course of time and solidified by diagenesis of the sandstone.
You can discover these traces today in Obernkirchener Sandstein® in the form of the typical wave surface from the bottom of a shallow body of water. This makes the Earth’s history an intrinsich part of your project.
