Sandstone is a sedimentary stone that is typically the result of quartzite stone being eroded and redeposited by either wind or water. Sandstone mostly consists of quartz, silica, iron oxide and calcium carbonate and are durable, weather, acid and thermal resistant and have crushing strength. Sandstones are most highly craftable and manageable, they can at most take a honed polish, and are used as garden and commercial landscapes, exterior wall cladding, panels, pillars, sculptures, arches,etc. They come in an array of colors & shades and can be chiseled and dressed to a smooth surface in various attractive shapes. The color of sandstone varies, depending on its composition. The most common sandstones have various shades of red, caused by iron oxide (rust). In some instances, there is a purple hue caused by manganese.
