SAND SAWN FINISH
Stone surface left as it comes from a gang saw; moderately smooth, granular surface varying with the texture and grade of stone.
A sedimentary rock consisting usually of quartz cemented with silica, iron oxide or calcium carbonate. Sandstone is durable, has a very high crushing and tensile strength, and a wide range of colors and textures.
A clean cut edge generally achieved by cutting with a diamond blade, gang saw or wire saw.
A finish obtained from the particular process employed to produce building stone. Varies in texture from smooth to rough and is coincident with the type of materials used in sawing; characterized as diamond sawn, sand sawn, chat sawn or shot sawn.
A foliated metamorphic rock (recrystallized) characterized by thin foliae that are composed predominantly of minerals of thin platy or prismatic habits and whose long dimensions are oriented in approximately parallel positions along the planes of foliation. Because of this foliated structure schists split readily along these planes and so possess a pronounced rock cleavage. The more common schists are composed of the micas and other mica-like minerals (such as chlorite) and generally contain subordinate quartz and/or feldspar of comparatively fine-grained texture; all gradations exist between schist and gneiss (coarsely foliated feldspathic rocks).
A lengthwise cut of a large quarry block of stone approximately 5'x 8' in size.
SNAPPED EDGE, QUARRY CUT or BROKEN EDGE
Generally refers to a natural breaking of a stone either by hand or machine. The break should be at right angles to the top and bottom surface.
SPLIT FACE (SAWED BED)
Usually sawed on the stone bed and split by hand or machine so that the face of the stone exhibits the natural quarry texture.
Obtained by sawing to accurate heights, then breaking by machine to required bed widths. (Normal bed widths are 3 1/2".)
A variety of limestone regarded as a product of chemical precipitation from hot springs. Travertine is cellular with the cells usually concentrated in thin layers that display a stalactitic structure. Some that take a polish are sold as marble, and may be classified as travertine marble under the class of "Commercial Marble."
Any stone used as a decorative facing material which is not meant to be load bearing.
