Whinstone is a term used in the quarrying industry to describe any hard dark-coloured rock. Examples include the igneous rocks, basalt and dolerite, as well as the sedimentary rock, chert. Description: Massive outcrops of whinstone occur include the Pentland Hills, Scotland and the Whin Sills, England.

On the Mohs Hardness Scale sandstone is rated as having a hardness between 6 and 7. The hardness of sandstone varies depending upon its composition. What rock is harder than sandstone? To understand why quartzite is harder than sandstone it helps to understand a bit about the rock cycle. Is sandstone hard to cut?

Cores of other sandstone types fracture with sharp edges or shatter into small sharp fragments. Crystallized Sandstones are white and sugary and in many cases very hard and brittle. Is sandstone a hard rock? Most sandstones are made up largely of quartz grains because quartz is a very hard and chemically-resistant mineral. Quartzite is a name

The hardness of sandstone may be difficult to test. If the sand grains have not been cemented well or have been cemented by calcite, the sandstone will seem softer. The individual quartz sand grains will still have a hardness of 7, but the rock may crumble or disaggregate in your hand, making it look soft.

Framework grains are sand-sized (0.0625-to-2-millimeter (0.00246 to 0.07874 in) diameter) detrital fragments that make up the bulk of a sandstone. Most framework grains are composed of quartz or feldspar, which are the common minerals most resistant minerals to weathering processes at the Earth's surface, as seen in the Goldich dissolution series. Framework grains can be classified i

The hardness of this sandstone can be determined by breaking the core as well as by examining the broken core's edges. The edge of this kind of sandstone core is relatively weak & crumbles with minor impact. Cores of other types of sandstone fracture with sharp edges and shatter into small as well as sharp fragments.
