Is granite homogeneous or heterogeneous substance? Granite is a heterogeneous substance. This is due to the fact that it does not appear to be consistently made of one material.
Granite Composition: Granite is an igneous rock that is composed primarily of four minerals. Magma cooling very slowly far under the earth's surface, allows crystals of the four minerals to grow large enough to be easily seen by the naked eye. These minerals are quartz, feldspar, mica, and usually hornblende.he geological definition of granite is any plutonic rock in which the mineral quartz makes up 10 to 50 per cent of the felsic components, and the ratio of alkali to total feldspar is between 65 and 95 per cent.. However you may find that commercial suppliers may not be so specific.
