Granite Surface Texture
Granite has a crystalline, granular structure, with a range of colors and consisting mostly of quartz, feldspars and minerals. Due to the fact the granite was formed over millions of years it has plenty of strength, permanence, solidity, quality and hardness. This of course makes it a great choice for a counter top surface. Most granite used for countertops is polished to a high gloss finish, however most granites have certain natural characteristics such as ” pitting”, “fissures” or “dull spots”. To fully appreciate the beauty of the rock you must first understand the geology behind it.
“Pitting” is normally due to the fact that granite is a natural product that has crystalline structure, sometimes resulting in small spaces between the varying mineral crystals. In some cases, certain tiny crystals may also be removed during the polishing process causing the pits to become more visible. Therefore this “pitting” cannot be avoided in all granite types. The good new however the pitting will not become worse with regular use or with the passage of time.
Like pitting, fissures/hairline cracks may also be noticeable in some granite colors. These are usually more visible in the larger quartz crystals. These surface fissures should not be confused with structural cracks that pearmeate the entire slab. Fissures are a natural result of the heating and cooling of the stone during its formation millions of years ago. Fissures will not grow or expand over time.
The composition of quartz, feldspars and other minerals will determine the final appearance of the polished granite surface. While the overall appearance will be that of a high gloss finish, some components within the granite may not accept the same level of polish as the rest of the crystals, which can result in “dull spots” or “water marks”. Often these spots are visible on the crystals which are present in some granite.
Some granites exhibit more pits, fissures and dull spots than others, and they may also be more or less visible depending on the lighting conditions present in a room. Pits, fissures and dull spots do not compromise the integrity of the granite in any way; they are natural characteristics and will not impair the function or durability of the material. They are an expression of nature.
