Is granite a homo or heterogeneous mixture?

A granite countertop is a heterogeneous mixture. Granite, the main material in a granite countertop, is a type of metamorphic rock that contains minerals such as quartz and feldspar. Quartz and feldspar are two different types of minerals which make up granite. Therefore, because there are two different types of minerals in one substance it makes it heterogeneous.
