As an igneous rock, granite is formed under very high heat and has a crystalline structure instead of a layered structure like sedimentary rock. Tile made from it is quite dense, with a strength similar to porcelain, says Dave Gobis, executive director of the Ceramic Tile Education Foundation.

Granite is a good choice for kitchen countertops; using tile rather than solid granite cuts the expense drastically. Make sure tiles are spaced closely to minimize grout staining; you can use tinted grout to achieve a more seamless look as well. Both the tile and the grout should be properly sealed.
