Quartzite, a natural metamorphic rock, forms slowly over time when quartz minerals compress into sandstone which then fuses into its final form under intense heat and pressure. The result is a virtually indestructible stone that is resistant to heat, stains, and scratches, making it ideal for use in bathroom or kitchen countertops. It also comes in many beautiful organic patterns and colors. Proper care for this porous stone includes regular resealing.
