Metamorphic Rock Created when other kinds of rocks are changed by great heat and pressure inside the earth. Marble, slate and quartzite are examples of metamorphic rocks.
Large pieces of stone, in a block form that have been extracted from the earth and cut.
The typical natural stone floor tile sizes are 12″x12″, 13″x13″, 16″x16″ and 18″x18″.
For millions of years, a combination of heat and pressure created blocks of natural stone, including granite, Marble, Travertine and Limestone and slate. As the earth’s crust began to grow and erode, it pushed minerals up from its core, forming massive rock deposits, which we refer to as “quarries”.
The amount and size of the pores in a stone,travertine is very porous and granite is not.
