Krensheim Muschelkalk: complete guide
Krensheim Muschelkalk is a German shelly limestone in grey-beige tones. It is chosen for outdoor and indoor settings that call for a robust stone with a natural, lively appearance.
History and origin
It comes from southern Germany, where the Triassic shelly limestones known as Muschelkalk are among the most traditional building stones. The name refers to the fragments of shells and marine organisms compacted in the rock. These limestones have long been used for façades, urban paving and stairs. Marmi di Carrara supplies it on request.
Look and veining
The grey-beige background is rich in shell fragments and small cavities, with variations towards grey-blue or yellow-beige depending on the bed. The slabs are lively and never identical. Honed finishes highlight the fossils, while bush-hammered or sandblasted ones make the surface more uniform and non-slip.
