Building stone that has been smooth cut, or dressed, into squared or rectangular blocks.
(1) In granites or marbles, a layer or sheet of the rock mass that is horizontal, commonly curved and lenticular, as developed by fractures. Sometimes applied also to the surface of parting between sheets.
(2) In stratified rocks, the unit layer formed by sedimentation; of variable thickness, and commonly tilted or distorted by subsequent deformation; generally develops a rock cleavage, parting, or jointing along the planes of stratification.
(3) The top or bottom of a joint, or natural bed/surface of stone parallel to its stratification.
A hard sandstone of characteristic blue, gray and buff colors quarried in the states of New York and Pennsylvania.
Textured surface obtained by brushing a stone with a coarse rotary-type wire brush.
A limestone containing not more than 5 percent of magnesium carbonate.
The lightweight outer skin of a building that does not carry any weight nor support the building, but which protects it from weather elements.
A natural rounded stone, large enough for use in paving. Commonly used to describe paving blocks, usually granite, which are generally cut to rectangular shapes.
A crystalline rock composed predominantly of one or more of the following materials: calcite, dolomite or serpentine, and capable of taking a polish.
A stone forming part of a corner or angle in a wall. Also a dedicatory stone laid at the formal inauguration of a building's construction, prominently located but not necessarily at the corner, and usually bearing the date of erection and often an inscription.
All stone cut or machined to given sizes, dimension or shape, and produced in accordance with working or shop drawings which have been developed from an architect's structural drawings.
Stone pre-cut and shaped to dimensions of specified sizes.
A limestone rich in magnesium carbonate, frequently somewhat crystalline in character. It is found in ledge formations in a wide variety of color tones and textures. Generally speaking, its crushing and tensile strengths are greater than the oolitic limestones, and its appearance shows greater variety in texture.
