Your granite countertops were formed deep within the earth as some of the hardest minerals within molten magma slowly cool and compress. This network of extremely dense interlocking-crystals is what makes granite so durable. Granite is primarily composed of feldspar, quartz, and mica but can also include a number of other minerals all contributing to your granite contertop's unique color, veining, and brilliancy.
Feldspar: The mineral that comprises the white portions of granite is feldspar.
Quartz: Quartz is the light-grey portions found within a granite slab.
The extreme denseness and strength of granite make it an ideal choice where durability is key.

Granite Counter Top Seams:
Granite countertops do not necessarily need to have a sealer applied to them. Due to the nature of natural stone surfaces granite is porous and is susceptible to staining. Properly applied sealers block liquids, dirt, and grime from seeping into the surface of this investment in your home. These granite sealers are applied at the time of installation.
Not all granite sealers are alike. It's important to understand what is being applied. Many cheap granite sealants need to be applied annually. While other can are backed by a manufacturer warranty and can last for several years.
