DEFINITION: Quartzite is a type of metamorphic rock that is formed from sandstone under high heat and pressure. It is primarily composed of quartz, which gives it a unique crystalline texture and appearance. Quartzite is extremely durable and resistant to heat, scratches, and other types of damage, making it a popular choice for use in kitchen countertops and flooring.

Quartzite is available in a range of colors, from white to gray, and may contain other minerals, such as mica, feldspar, or iron oxide, which can give it a distinctive color or pattern. Quartzite is a hard and dense material, which makes it difficult to work with, requiring specialized equipment and expertise for cutting, shaping, and polishing. It is also non-porous, which makes it resistant to water damage and staining, and easy to clean and maintain.
