Stone & Tile – Classifications

Porcelain and Ceramic- are both man made from clay, sand, quartz, and other minerals. They are durable, easy to clean, and fairly easy to maintain. Both porcelain and ceramic can be glazed or unglazed. Porcelain is the stronger of the two due to how it is processed and fired.

Travertine- is a porous sedimentary stone that is formed in hot springs. Travertine is somewhere between marble and limestone in composition, yet it is different from both. The holes or pits within the stone are caused by calcium carbonate and can be factory filled or left unfilled for a more rustic look.

Marble- is a metamorphic crystalline rock formed from limestone that has naturally been exposed to intense pressure and high temperatures. Marble is sensitive to acid and can require more maintenance than other types of stone.

Onyx- is similar to marble and may even be considered as a type of marble by some, due to its mineral content. Onyx is a calcium based sedimentary rock that has translucent properties. Like marble, onyx is sensitive to acid which means it can etch easily.

Limestone- is a sedimentary stone made from calcite and dolomite. Limestone is very porous and can stain easily if not properly maintained.

Slate- Slate is a fine grained metamorphic stone composed mostly of clay minerals or micas. It is formed from shale or mud stone that is naturally exposed to pressure and high temperatures. Slate is more rustic in appearance and is commonly used.

Quartzite- is a dense metamorphic quartz based stone. Quartzite started out as sandstone that, through heat and pressure has transformed into a more durable stone similar to granite but may look more like marble.

Stone Classifications

Granite- is an igneous stone that solidifies when molten rock has cooled beneath the earth’s surface. It is very commonly used in homes especially as counter tops because it’s easy to maintain. Granite is very durable and is one of the hardest stones used in design.

Grout- is a mixture of water, sand, and cement that is used to fill in space between tiles. Grout helps absorb moisture that may be on the stone but will also equally absorb any dirt and debris. Grout can be sanded or non-sanded, sanded grout being more durable and more commonly used.
