Glossary of Terms

Brushed Finish
Obtained by brushing a stone with a coarse rotary-type wire brush.

Chiseled Edge
A process of mechanically chipping the tile edge, thus giving the stone a rustic, aged appearance.

A process of end-cutting blocks of stone which yields a less-linear, more rounded, “wavy” pattern.

A trade expression used to indicate the filling of natural voids in stone units with cements or synthetic resins and similar materials.

An aggressively-textured finish, achieved by exposing certain types of stones to intense flame.

Gauged & Ungauged
Refers to slate cleft out of blocks into tile. Gauged slate is ground or sawn to produce a more uniform thickness. Ungauged slate is hand-cleft and can have variations in thickness up to 5/8 of an inch.

Honed Finish
A smooth, satin (but not shiny) finish on the stone.

The space between tiles that is filled with grout.

Metamorphic Rock
Rock altered in appearance, density, crystalline structure, and in some cases, mineral composition, by high temperature or intense pressure, or both. Includes slate derived from shale, quartz-based stone from quartzitic sand, and true marble from limestone.

Polished Finish
A high-gloss finish attained by machine-grinding and buffing the stone.

A finishing process of blasting the surface of stone with sand, which yields a rough, porous finish.

Sedimentary Rock
Rocks formed of sediments laid down in successive strata or layers. The materials of which they are formed are derived from preexisting rocks or the skeletal remains of sea creatures.

Large, thin, flat pieces of stone cut from large blocks of stone. Usually 2 centimeters (3/4 inch) or 3 centimeters (1-1/4 inch) thick, slabs are often fabricated into kitchen counter tops or used as cladding on vertical surfaces.

Tumbled Stone
Marble, travertine, and slate tumbled in a solution of water, sand and river rock, producing tiles with an old-world, weathered look.

A process opposite of cross-cutting, where the vein in the stone is shown as a linear pattern.
