Granite is a deep rock (plutonite) that consists mainly of feldspar, quartz and mica. It was formed by the solidification of magma at a depth of more than 2000 m below the earth's surface. Granite is a rock that is common worldwide and is mined in blocks and has no stratification.
Appearance: Usually medium to coarse-grained with a homogeneous structure, with granites whose crystals are about the same size, while the crystals of other varieties are unevenly grained. Its colour spectrum ranges from light grey to bluish and greenish, as well as from reddish to yellowish, depending on the composition.
Properties: Granite is considered hard rock and is ideal for outdoor use due to its hardness and weather resistance. Granite is considered resistant to de-icing salt, frost and acid. It is insensitive to paint abrasion and can be sanded and polished.
Use in construction: pavement/garden slabs, paving and curbs, façade cladding, roof shingles, interior wall and floor coverings, kitchen worktops, gravel material, monuments and fountains.
Examples of well-known granite varieties: Flossenbürger Granite, Tittlinger Granite, Kösseine-Granite.
