Actually,a pure quartz sandstone,quartzite in india is basically a metamorphic and non-foilated rock.Sandstone gets converted into quartzite through pressure and heating that occur due to tectonic compression inside orogenic belts.Generally white to grey in color,this natural stone also exists in different shades of red and pink because of varying proportions of iron oxides(Fe2O3) in it.Nevertheless,quartzite does occur in other colors,such as orange,blue,green,and yellow. Once used for making stone tools during the prehistoric era,quartzite stone currently finds applications in numerous fields,not just because of its color variants,but excellent properties.The angular shape and hardness of the stone make it apt for making railway ballast.In comparison to granite,quartzite from quartzite manufacturers is more durable and resistant to stains and harsh weather conditions,hence extensively used in the construction sector as well as interior and exterior designing projects.
