Glossary of Terms

Glossary is usually defined as an alphabetical list of technical terms in some specialized field of knowledge. This knowledge base glossary provides a collection of knowledge base documents that define many technical terms. These terms are arranged alphabetically, but you can quickly jump to a specific term by selecting its first letter from the index of the knowledge base glossary below.

SAND BLASTED
A matte-textured surface finish with no gloss, finished by application of pressure
SANDSTONE
Arenaceous sedimentary rock composed mainly of quartz with feldspar as a possible minor component. Sandstones are clastic in origin (opposed to organic or chemical) and the binding agents are mostly calcite, clay and silica. See quartz-based stone
SAWED EDGE
A clean-cut edge generally achieved by cutting with a diamond blade, gang saw, or wire saw
SAWED FINISH
A finish obtained from the process used in producing blocks, slabs, or other units of building stone. It varies in texture from smooth to rough, and is typically named for the type of material used in sawing, e.g. diamond sawn, sand sawn, chat sawn, and shot sawn
SEALING
1. To make a veneer joint watertight with an elastic adhesive compound. 2. Application of a below surface treatment to retard staining
SEDIMENTARY STONES
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
SERPENTINE
Hydrous Magnesium Iron Phyllosilicate [(Mg, Fe)3 Si2 O5 (OH)4] The main mineral composing most green marbles and ophicalcite. Serpentine-based rocks are called Serpentinite. A hydrous magnesium silicate material; generally dark green in color with markings of white, light green, or black. Considered commercially as a marble because it can be polished
SETTER
An experienced journeyman who installs dimension stone
SHALE
A fine grain sedimentary rock formed by the compaction of clay, silt or mud. It has a finely laminated structure which causes the stone to split readily, especially on weathered surfaces. It is commonly sold as slate though shale is not as hard as slate. It may be red, black, brown or gray
SLATE
Low-grade regional metamorphism of pelitic sediments of shale, mudstone or fine-grained tuff
SOUNDNESS
A property of stone used to describe relative freedom from cracks, faults, voids, and similar imperfections found in untreated stone. One of the characteristics encountered in fabrication
SPALL
A chip or splinter separated from the main mass of a stone
STUNNED CRYSTALS, (MARKS)
Permanent damage occurring on the crystals of true geological marble when subjected to high stress. They appear like whitish, deep marking under the surface of the stone
