Because of granite's unique composition and creation
Because of granite's unique composition and creation, it is extremely durable, not excessively prone to chips or scratching, and can withstand extreme heat which is why it is especially popular in both residential and professional kitchens. Granite, once sealed, is resistant to stains, molds, and bacteria. It is easy to clean requiring only a damp cloth with simple soap and water.
While most granite choices need to be sealed in order to look their best and protect the granite, if you are considering black granite there are a few things to keep in mind. Unlike other colors of granite, black granite is extremely dense and uniform in appearance and are typically the least susceptible to water absorption. In addition, there have been reports of overseas factories chemically treating Indian Absolute Black Granite in order to achieve deeper, darker black granite. In these cases, the granite is more sensitive to food stains, chemicals, UV rays and cleaning products.
