Granite is formed by the solidification of magma in high temperature and high pressure conditions. Granulometry is medium-large and occasionally includes mega-crystals. From a physical point of view, granites are extremely compact and have high hardness (6-7 on the Mohs scale) and mechanical resistance values. Granite is resistant to wear, exposure to atmospheric agents and pollution; granites are widely used in the modern building industry, especially for flooring/paving and monuments. Polished or brushed, this hard-wearing and attractive material is often used cooking tops in many kitchen suites.
