A mechanical process which produces textured surfaces that vary from subtle to rough.
Placing mortar on stone units with a trowel before setting them into position.
An external corner formed by two stone panels with one head.
The first step in the finishing process of a stone tile. Coarse abrasives pads are mounted to the bottom of rotating wheels that under extreme pressure and rotation speed are applied to the face of the stone. This process grinds the stone to a uniform and consistent thickness of ±1 mm tolerance, which is crucial for the installation of tile in a thin-set application. Calibration is applicable only to dense stones that can take a honed or polished finish, such as limestone, marble, and granite tile. The term is often erroneously applied to slates, quartzites, and other cleftface stones, where the precision of the calibration process is not possible. Sawn-back or ground-back techniques are applied to these types of stones, and are correctly called "gauging," which is not as precision-oriented as calibration.

Rough-surfaced stones such as slates that are cleaved or separated along a natural seam are referred to as natural cleft. These types of stones were formed as a result of metamorphic foliation.
COF - coefficient of friction
Most manufacturers will have a rating system that is based on or supported by the American Society for Testing & Materials (ASTM). Many times you can find these ratings on the tile sample or in the product catalog. One rating system measures Slip Resistance, which is measured by its Coefficient of Friction (COF). The higher the COF the more slip resistant the tile. This is important when selecting a floor tile for areas that get wet, such as your shower or bathroom floor. Other ratings listed by the manufacturer might include: scratch resistance, moisture absorption, chemical resistance and breaking strength.
color body porcelain tile (aka. thru color porcelain tile)
Technically-advanced glazed porcelain. The porcelain body and surface glaze are colored with the same pigments. The result is a glazed tile with consistent color throughout the body. The tile is fired in a kiln at approximately 2,000 degrees, creating a hard, non-porous, impermeable tile with a water absorption rate of 0.5% or less.

The time required for the thin-set below the tile to become hard and set.
DCOF - dynamic coefficient of friction
Dynamic coefficient of friction (DCOF) is the frictional resistance one pushes against when already in motion. According to the ANSI A137.1–2012 standard, ceramic tiles selected for level interior spaces expected to be walked upon when wet must have a minimum wet DCOF AcuTest value of 0.42. Tiles with a lower value are not necessarily restricted to dry areas only, but rather are restricted to applications where they are kept dry when walked upon. In the case of residential bathrooms, the common use of bathmats can accomplish this. Similarly, in entranceways, the use of entrance mats can accomplish the same.

manufactured stone / agglomerate stone
This is a synthetic stone made from natural stone chips suspended in a binder such as cement, epoxy resins or polyester. Some of the most popular types of manufactured stone products are those made mostly of quartz. The natural quartz gives the product depth and radiance while at the same time strength and consistency. Manufactured Stone is strong, it has four times the flexural strength of granite, so there's less chance of chipping or cracking. It's also called Agglomerate Stone. The most well known agglomerated stone is poured-in-place terrazzo, used in building for thousands of years.

Colorless or colored glaze with low gloss
Tiles of different sizes that can work together in a pattern.
As the density of the tile increases, the amount of moisture that tile can absorb becomes less. Tile density means that, as the weight or the density of the tile increases, it becomes a stronger tile. Tile density and moisture absorption have an indirect relationship to each other. What this means is that as the density of the tile increases the moisture absorption rate becomes less. Tile density and moisture absorption is important for you to understand when selecting tile for different applications.

slang term referring to thick–bed mortar consisting of sand and cement.
A product of nature. A stone such as granite, marble, limestone, slate, travertine, or sandstone that is formed by nature, and is not artificial or manmade.
Tile is usually referred to by its nominal size, not its actual size. During the firing process, ceramic tile will shrink, on average, by about 10% in size. For example a 12" by 12" floor tile will actually measure 11-7/8 inches square. Currently, the most popular ceramic floor tile are the larger sized tiles such as 13" by 13", 16" by 16" and 18" by 18" sizes.

A tile finish that features softly rounded edges, thus giving the tile a pillowed look.
A high-gloss finish attained by machine-grinding and buffing the stone.
Porcelain tile is made up of 50% feldspar and is fired at a much higher temperature than regular ceramic tile. This makes porcelain tile much harder and more dense than other tile products. Because of its highly durable make-up, porcelain is more resistant to scratches and can withstand temperature extremes. Also, because porcelain is non-porous, it's very stain resistant, has very low water absorption ratings (Less than 0.5%) and thus can be used for interior and exterior applications as well as heavy-use and commercial areas. Finally, because porcelain's color goes all the way through, small scratches or chips are less noticeable.

Tile density means that, as the weight or the density of the tile increases, it becomes a stronger tile. Moisture absorption means that, as the density of the tile increases, the amount of moisture that tile can absorb becomes less. Tile density and moisture absorption have an indirect relationship to each other. What this means is that as the density of the tile increases the moisture absorption rate becomes less. Tile density and moisture absorption is important for you to understand when selecting tile for different applications.
