Rock description

The removable bench height in Burgpreppach ranges from 1 to 3 meters. The color ranges from light gray to light brown. Its color comes from limonite , a complex iron compound. It is a fine-grained, fine-pored sandstone , which is largely weather-resistant due to its pebbly bond. It consists of 93 percent quartz and fragments, its share of alkali feldspar is 1 percent and the secondary mixture components are 2 percent of muscovite , rutile , tourmaline , opaque iron ore and limonite. Weathering can cause surface sanding.

Use and structures

This sandstone is suitable for solid buildings, masonry, stairs and floor coverings, wall panels and facade panels. Burgpreppacher sandstone was used in Bayreuth on numerous buildings and on the castle and church in Erlangen , for the residence, cathedral and bridges in Bamberg and also for the Viktoriaversicherung building on Lenbachplatz in Munich. The stone was also used on the Reichstag building in Berlin and the Hamburg City Hall . Its fine grain makes it suitable for stone carving work .
