Architectural stone includes dimension stone and rough stone. Dimension
stone, which is worked and often polished, is used in sculpture
and to produce cut-to-size panels, tiles, cut stone, curbstones,
veneers, and monuments. Rough or roughly dressed stone is used to
produce cobblestones, flagstones, and paving stones.
The rocks most commonly used are granite, limestone, marble, sandstone,
and slate. The stone market is subject to technical and aesthetic
standards, such as those related to porosity, hardness, or resistance.
The sale of rough or processed stone is highly dependent on a competitive
international market, governed by well-established distribution
networks.
Some specifications
Dimension stone has specific form and dimensions.
It is usually extracted from quarries as large blocks, which are
sawn at a plant into cut-to size panels or tiles of different sizes
and processed to produce various finishes.
Cut stone is shaped by hand or using a guillotine
splitter. Rough blocks are processed into cut stone of various sizes.
Cobblestone is small roughly dressed or undressed stone. Flagstones
are large and thin.
