Why granite discoloring?

Answer 1

The colors are due to the various minerals present. The white is dues to the presence of minerals such as quartz and albite (a feldspar). The pink is the result of potassium feldspar. The dark portions are due to the presence of hornblende and/or biotite.

Answer 2

Granite contains quartz, amphibole, micas, and both plagioclase feldspars (generally white to gray in color) and orthoclase feldspar (usually pinkish). The amount and color of the various minerals present in a sample can affect its color. Granites are typically pinkish/gray.

In the trades the term granite is used more loosely, often describing any coarse grained igneous rock. In those cases as well, mineral content determines the color, and the colors are widely variable.

Answer 3

Granite can become discolored due to exposure to certain chemicals, oils, or acids that can react with the minerals in the stone. Other factors such as improper cleaning techniques, high heat, or moisture can also contribute to discoloration. To prevent discoloration, it's important to clean granite surfaces regularly with a pH-neutral cleaner and avoid using harsh chemicals or abrasive materials.

Answer 4

It is light in color because of the abundance of silicate minerals like feldspars and quartz.
