Natural Stone Fabrication
The natural stone or dimension stone (for example,
granite) is shaped using cutting and finishing equipment in the shop of the
fabricator. The edges are commonly put on by hand-held routers, grinders, or CNC
equipment. If the stone has a highly varigated pattern, the stone may be laid
out in final position in the shop for the customer's inspection. Then the
countertop assembly is installed on the job site. Initial slab fabrication
usually takes place at or near the quarry of origin, with blocks being sawn to
thickness and then machined into standard widths, before being surface polished
and edged. This method removes the need to ship waste material, and reduces the
time needed to prepare client orders. A wide range of details may be
pre-fabricated on premises, allowing for easier and faster
installation of different stone elements.
||Polished - a
glossy surface which brings out the full color and character of the
||Hone - a
satin smooth surface finish with little or no gloss. This is recommended
for commercial floors.
||Thermal - a
surface treatment applied by intense heat flaming.
Sawed - finish produced by sawing with a diamond toothed saw.
- a surface finish resulting from the gang- or frame saw process.
Hammered - a mechanical process which produces textured surfaces.
Texture varies from subtle to rough.
Types of Natural Stone
is a common and widely occurring type of intrusive, felsic, igneous
rock. Granites usually have a medium- to coarse-grained texture.
Occasionally some individual crystals are larger than the groundmass, in
which case the texture is known as porphyritic. A granitic rock with a
porphyritic texture is sometimes known as a porphyry.
Granites can be pink to gray in color, depending on their chemistry and
mineralogy. By definition, granite has a color index - the percentage of
the rock made up of dark minerals - of less than 25%. Granite is usually
found in the continental plates of the Earth's crust. Granite is nearly
always massive, hard and tough. Granite has gained popularity
for use as a construction stone more widely used for granite countertops,
granite floors, granite tiles, granite tubs, granite showers, granite fireplace
hearths, granite columns, granite statues and granite building stone.
is a metamorphic rock composed of crystallized carbonate minerals,
most commonly calcite or dolomite. Geologists use the term marble to
refer to metamorphosed limestone; however stonemasons use the term more
broadly to encompass un-metamorphosed limestone. Marble is commonly used
for sculpture and as a building material.
White marble has been prized for its use in sculptures since classical
times. This preference has to do with its softness, relative isotropy
and homogeneity, and a relative resistance to shattering. Also, the low
index of refraction of calcite allows light to give "life" to marble
sculptures of the human body. Construction Marble is a stone which is
composed of calcite, dolomite or serpentine which is capable of taking a
polish. Granite is nearly always massive, hard and tough. Granite has
been a popular building stone for centuries and more recently marble has gained
popularity and is used for marble countertops, marble floors, marble tiles,
marble tubs, marble showers, marble fireplace hearths, marble columns, marble
statues and marble building stone.
is a fine-grained, foliated, homogeneous metamorphic rock derived from
an original shale-type sedimentary rock composed of clay or volcanic ash
through low-grade regional metamorphism. The result is a foliated rock
in which the foliation may not correspond to the original sedimentary
Slate is frequently grey in color, especially when seen in masse
covering roofs. However, slate occurs in a variety of colors even from a single
locality; slate can be found in many shades of grey, from pale to dark, and may
also be purple, green or cyan. Slate countertops and sinks
have become very popular for homeowners, kitchen designers and contractors.
Slate tiles, roofing tiles, slate building stones, slate fireplace hearths,
slate tubs and showers are also gaining popularity for homeowners and
Soapstone, also known as steatite or soap rock is largely composed of the mineral talc and is thus rich
in magnesium. It is produced by dynamo thermal metamorphism and metasomatism, which occurs in the areas where tectonic plates are
sub ducted, changing rocks by heat and pressure, with influx of fluids,
but without melting.
It has been a medium for carving for thousands of years. Soapstone is
used for inlaid designs, sculpture, coasters, and kitchen countertops
and sinks. There is a natural beauty of the design in the soapstone
which is one reason it's gained popularity with commercial construction, as well
as residential home and business building architects and designers including
soapstone countertops, soapstone tubs and showers, soapstone fireplace hearths,
soapstone flooring, soapstone tiles.
is a sedimentary rock composed largely of the minerals calcite and/or
aragonite, which are different crystal forms of calcium carbonate. Like
most other sedimentary rocks, limestone is composed of grains;
however, some limestone does not consist of grains at all, and are formed
completely by the chemical precipitation of calcite or aragonite or
Limestone has been used as a building material for hundreds of years
including sills, caps, wall caps, pavers pool coping, Treads, garden steppers,
statues and garden walls & tumbled edging but as commercial and residential
building designers and architects turned their focus to bringing the outdoors
indoors, designers began using limestone for limestone countertops, limestone
sinks, limestone flooring, limestone tubs, limestone showers, limestone tile,
limestone fireplace surrounds and more.
