The beauty and sheer versatility of
natural stone from marble to slate,
limestone to granite has been admired for many thousands of years.
There are three kinds of rock types:
Igneous solidified magma or lava formed
after volcanic activity. Extremely hard.
Examples: granite, basalt.
Sedimentary weathering of existing rocks
produced sediment which settled in layers and
gradually lithified (turned to stone) by compaction
and cementation. Examples: limestone, travertine.
Metamorphic Metamorphism is the
transformation of one rock type into another,
brought about by heat, pressure or chemically
active fluids. Examples: Marble (originally
limestone or dolostone), slate (previously
sedimentary shale or mudstone)
Textures and finishes:
Brushed the stones surface is brushed with
rotary diamond pads, resulting in a textured
finish to the surface and rounded edges.
Cushioned, pillowed where the straight
edges of a tile have been rounded and
softened.
Filled where voids, pits and holes (a natural
characteristic of some stone) have been filled
with a resin to create a smooth surface.
Honed a machine process which results in a
smooth, matt surface.
Lightly polished the surface is polished to a
softly reflective sheen rather than a high gloss.
Polished where the surface is buffed by
machine, resulting in an even, smooth and
highly reflective surface.
Tumbled the surfaces of the stone have been
textured, worn and weathered by contact with
abrasive materials.
Unfilled where the pits and voids within
travertine tiles have not been filled. These can
be grout-filled during installation
