Granite is used for kitchen and bathroom countertops because of its beauty and durability.
Where does granite come from? Many, many years ago, deep underground, volcanic action melted rock into liquid magma. The magma cooled and solidified, and the result is called igneous rock. Granite is one type of igneous rock. Granite’s crystal structure comes from quartz and feldspars. There are many ranges of colors of granite depending primarily on the feldspars. It may also contain mica or other dark minerals. Granite comes in a variety of patterns from similar grain to multicolored stone with veins or various shades depending on how the minerals are distributed. All of this is what makes granite strong, durable and unique.
Granite is almost always polished to a high-gloss finish when used for kitchen or bathroom counter tops. This brings out the unique features of each piece of stone. Depending on where it was mined, granite can include dull spots, fissures or pitting. These add to the stone’s beauty and one of a kind quality.
As mentioned previously, granite is made up of a different mixture of quartz, feldspars, and other minerals and that is what gives granite its fine appearance. Sometimes, with a high-gloss finish, some of the crystals in the granite do not polish as shiny as other areas. These areas are known as dull spots or watermarks and can sometimes be seen in the darker areas.
Another characteristic of granite is referred to as pitting. Pitting is what happens when there are small spaces between the different mineral crystals in the stone. Sometimes, while the granite is being polished, some of the small crystals are removed, making the pits easier to see. Different steps are taken while finishing the stone to make the pits less obvious, but they cannot be completely eliminated. Just like freckles or beauty marks on a person, pitting makes each granite slab unique and different from any other. Pitting does not worsen over time with normal use.
Yet another characteristic of granite are fissures, which were created during the cooling process when different flows of hot liquid magma came together and became a single stone. These fissures have always been a part of a specific piece of granite and will not increase or grow as time goes on.
Depending on the piece of granite that you get, it may have more or less pitting, dull spots or fissures as each natural stone is unique. How easily each of these characteristics can be seen also depends on the lighting in the room. Lighting conditions definitely affect how the granite appears.
*** Important ***
None of these characteristics, pits, dull spots, or fissures, affect the quality or integrity of the piece of granite in any way. They are naturally caused from millions of years of volcanic heating, cooling and formation. They make the stone unique, add character to each piece of granite, and make it stand out from manmade materials.
