The main minerals in granite are quartz, feldspar, hornblende and mica. These minerals are extremely hard, making granite one of the hardest materials found in nature, second only to diamond. Because granite is so hard, it resists scratching, chipping, and discoloration due to heat, making it ideally suited for countertops in your home. It can be used in virtually any application in your home, including kitchens, baths, bars and fireplaces. Because granite is a natural product, there are an almost endless array of colors and patterning available. Some display small crystals that are uniform and consistent throughout the slab, while others show elegantly flowing movement or large, random crystallization patterns. Granite now comes in several different finishes, including, polished, honed, leather-ed, antiqued, flamed, and brushed.
Quartzite is a natural stone with properties similar to granite, including hardness and durability. The peculiarities of this stone’s formation make it highly resistant to heat and water, meaning it will remain damage-free for a long time. Additionally, it has a high resistance to the acids that cause etching. It’s Low Maintenance if you have sealed your quartzite countertop, it will be easy to clean and maintain. Use mild dishwashing soap and warm water to clean spills and you’ll get a spotless countertop ready to use. Avoid chemical-based cleaners as these can damage the sealant.
Marble is composed of calcite, making it relatively soft. Pure marble is almost entirely white though it can vary in color from white to black. Impurities such as silica, iron oxide and graphite give it its characteristic rich veining, clouding and color. Because marble forms under varying degrees of heat and pressure, it exhibits a broad range of denseness and hardness. Marble is typically specified for use in baths and as fireplace surrounds due to its relative softness. Generally, marble is not suitable for kitchens because it does scratch and chip easier than granite or quartz. However, because marble develops a patina as it ages in the home, it can make beautiful “old fashioned” looking kitchen countertops.
