Washable Fossil Natural Sandstone

Sandstone, the sedimentary rock is composed
of small grains cemented by silica, with felspathic, or calcareous
cementing material. Sandstone is mostly formed in layers and
has varied applications as building stones. The formation
of sandstone is a result of consolidation of sand and held
together by a natural cement, such as silica. The consolidation
takes place when the masses of sand are deposited by wind,
water or other natural forces. The durability of rock depends
on the cementing material. Being homogeneous and soft, sandstone
can be easily carved and chiseled into various artifacts.
The color of the rock is largely determined by the cementing
material iron oxides for example produces red or reddish-brown
sandstone, and the other materials produce sandstone in the
shades white, gray or yellow.
