Quartzite is an extremely hard rock that is not water or acid soluble.
What is hareder granite or sandstone.
But it s incredibly difficult to carve making it a less obvious option for building masonry projects where heritage isn t a consideration.
Marble basically classifies into four groups which include.
Limestone tends to be more evenly colored than sandstone or granite and its very fine grain makes it relatively easy to cut into all sorts of decorative shapes.
Granite is available in white black grey orange pink colors.
The hardness of granite and sandstone is varying between 6 7.
Both granite and quartzsite are natural stones but quartzite is a much harder stone.
Granite is a very hard granular crystalline igneous rock which consists mainly of quartz mica and feldspar and is often used as building stone sandstone is defined as a rock which is composed of sand sized grains of various minerals mostly of uniform size and often are smooth and rounded.
As a general rule though an igneous rock will tend to be better welded together than a sedimentary rock and thus harder in the sense of more durable.
Marble is relatively hard but not as hard as granite.
Granite is extremely hard and less affected by the freeze thaw cycle the forces of abrasion and the surface exfoliation processes that are all a part of physical weathering.
Slate is a metamorphic rock that is dense strong acid resistant and.
Its color range is a bit more limited than granite or sandstone.
Depends on the cementation of the sand grains in the sandstone.
But granite is an igneous rock which means that it has crystallized and solidified from lavas molten state.
Granite is harder longer lasting and easier to clean.
The hardness of marble is 3 4 and that of sandstone is 6 7.
A quartzite a highly silicified and well cemented sandstone would be harder and more durable than a feldspar rich granite.
Dark gray blue gray pale gray cream and tan are usually the easiest to find.
In addition if you have granite that is an unusual color it may lose value if it goes out.
Granite and sandstone both are used in interior and exterior home designing projects.

Sandstone is easy to work and install.
They both have different physical properties depending upon its nature.
Groups a b c and d.
The types of marble are breccia marble carrara marble calacatta marble cultured marble polished marble honed marble sand marble whereas types of sandstone are grey sandstones crystallized sandstones hard sandstones carbonate cemented sandstones and ganister.
Granite can provide a financial benefit as well as homeowners generally recover 100 percent or more of the installation costs when selling their home.
A gravestone made of granite will therefore resist fracturing cracking and chipping longer than a sandstone marker found in the same location.
