Dalski Stone Products : Sandstone
Sandstone is a sedimentary rock that consists of consolidated sand grains (mainly quartz and feldspar) cemented together with a variety of minerals that vary in colour depending on the region in which they are found. The different cementing materials (silicates, iron oxides, limonite, calcite and clays) make one sandstone behave very differently from another. Sandstones containing silica are quite hard, strong and decay resistant, while those that contain calcite resemble limestone in their susceptibility to acid damage, and those containing clay absorb water and deteriorate more easily.
