Glossary

Antiqued

A term that describes the various ageing / distressing processes used to achieve a worn look on the stone.  The effect of the various antiquing methods will vary dependant on the stone and the country of origin.

Brushed

A method of finishing the stone which gives a very slightly textured surface and a subtle softened edge.  The effect of brushing can differ dependant on the stone type.

Calibrated

A term that indicates that the tiles are of a uniformed thickness.

Fissure

This is a thin line of mineral veining which normally contrasts with the base colour of the stone and can often be mistaken for a crack in the tile.

Flag

Used to refer to a large stone tile which has a greater depth.

Fossils

Fossils are remnants of past animals or plants.  These are generally apparent in Limestone and Marble, and occasionally in Sandstone.

Free Length

Free lengths have a fixed width and varying lengths ranging anywhere from either 500mm or 600mm up to a maximum of 1000mm, laid as a random brick bond.

Honed

This is a smooth non reflective matt finish given to the stone.

Honed and Filled

This term relates to the stone Travertine, which has surface pits and holes.  The holes are filled at source using a resin and are then machined down to a smooth matt surface. 

Minerals

One or more minerals bind to form a rock.  These are non-living solids that are found in nature and may be sensitive to prolonged exposure to moisture.  Quartz and Calcite are the most common minerals l found in stone.

Opus

This a repeating modular pattern that normally combines four different tile sizes to create a random effect.  Please note that the stones available in a random pattern are sold to the nearest full modular pattern.

Polished

This is highly reflective gloss finish applied to the stone, most commonly found in marble.

Porcelain

Porcelain tiles are ceramic tiles commonly used to cover floors and walls, with a water absorption rate of less than 0.5 percent. The clay used to build porcelain tiles is generally more dense and less porous than ceramic tiles.  Porcelain is generally available in three finishes, Honed, Polished and Grip/ anti slip.

Riven

A textured surface, cleft face which is achieved by splitting blocks of stone along natural laminations.  This is normally found in Slate and Sandstone.

Slip Resistance

This relates to the amount of a grip a tiles has, commonly required for commercial areas rather than residential.  The tile is normally tested using the Pendulum or Ramp test.

Splitface

A method of hand finishing which gives a highly textured tactile surface giving a 3D effect.  Splitface products come in varying materials and are often used for feature walls available in cladding wall panels.

Tumbled

A method of ageing the stone, the tiles are tumbled to give a rounded antiqued edge finish.  On certain products this finishing process can leave the surface of the stone slightly more textured.

Uncalibrated

This term relates to varying thickness between tiles normally found in Riven Slate and Sandstone.  Grading would be required prior to fixing and more adhesive is normally required for bedding up.

Unfilled

This term normally relates to Travertine due to the surface pits and holes.  An unfilled finish leaves the pits and holes exposed.  Unfilled Travertine will need to be slurry grouted across the surface of the stone in order to ensure that the holes are filled.
