A good example is granite which is a very hard plutonic rock.

Is granite volcanic.

Granite is a light colored igneous rock with grains large enough to be visible with the unaided eye. All magma develops underground in the lower crust or upper mantle because of the intense heat there. Ask students how they can determine this. Volcano contains quartz mica feldspar garnet and biotite.

Volcano granite is a kind of multi colored black granite quarried in brazil. Because this stone has areas of quartz which are very hard and other areas of the slab which are softer due to the high concentration of mica it is normal for the edge detail to have some wave to it after fabrication. Volcanic rocks cool quickly so the minerals do. Plutonic rocks such as granite cool slowly in a relatively undisturbed environment permitting the growth of large mineral crystals which can easily be seen by the unaided eye.
