Quarry tile production has its “roots” in the brick
making industry and uses raw material very similar to that used
in the manufacture of brick products. “Natural” and “durable” are
the words best used to describe hard-fired - high quality - quarry
tiles.
These low absorption tiles are manufactured then hard fired in
kilns at temperatures sometimes exceeding 2,000 degrees Fahrenheit.
Not all quarry tile is manufactured to such high quality standards
as to be considered “vitreous” or low absorption.
Metropolitan
quarry tile meets this standard. They are suitable for the most
demanding installations and are often the tile of choice for areas
such as commercial kitchens.
Quarry tiles are not produced in a quarry as might be suggested
by the name. They are manufactured. High quality quarry tiles are
made from a mixture of natural ingredients including clays and
shales.
They are extruded through a die and cut. This extrusion
process creates a much tighter/denser body than can be achieved
through other processes. The die also creates a ribbed back on
the tile to improve mortar adhesion. Once extruded, the tiles are
sent through a drier and fired in a kiln.
Because high quality quarry tiles are extruded and unglazed, they
are both naturally appealing and very practical. These tiles are
slip resisting and are an excellent choice for areas subject to
heavy spills and moisture. They also perform well in outdoor applications
- even in extreme climates.
High quality quarry tiles also have a tight die skin surface making
them resistant to soiling*.
Quarry tiles get their color from the choice of natural raw
materials put into the “mix” to create the tile.
Quarry tiles with a base of shale generally have a red or
brown color. Tiles with a base of clay generally have a gray
or beige
color. Some quarry tile is produced with a shade variation
from tile to tile.
This classic architectural look (sometimes
known as flashing) is achieved through controlling the flow
of oxygen and gases in the kiln. Whether monotone or with
color variation, all quarry tile colors have a natural look
that
matches well with other design elements.
This combination of features, along with the thickness of
the tiles - most quality quarry tiles are either 3/8” or 1/2” thick – makes
them the right choice for demanding commercial and residential
applications indoors and out.
*For areas susceptible to heavy spills and moisture you may choose
to seal the tile with a penetrating sealer.
