The primary method of quarrying this kind of stone is by splitting. Until scarcely a hundred years ago, sawing and polishing granite was done with great difficulties and using quartz sand and steel. Only since Corundum (a gem with a hardness on Mohs scale of 9) can be synthesized and used as an abrasive, it is economically feasible to saw granite into slaps.
In quarrying, rock fragmentation is very important since the rock sizes produced by a blast must be match the post process machinery such as hauling trucks and rock crushers. Normally, tight space blasting patterns are used to obtain good fragmentation. with the use of explosives this results in excessive chargin and an increase in a number of risks such as fly rock, rock vibration, noise and other issues …

The method produced a large amount of stone cheaply. An alternative method of blasting used more recently in some Scottish quarries (e.g. Locharbriggs and the new Dunmore quarries) uses the rapid conversion of liquid carbon dioxide into a gas to produce the relatively slow heaving action necessary to move the sandstone without shattering it.
