scene; your shiny new kitchen is now fully installed with the pièce de
résistance, a shiny granite worktop being the final part of the jigsaw. But
have given a thought as to where that shiny (and very heavy) slab of stone came
a light-coloured igneous rock with grains large enough to be visible with the
unaided eye. It forms from the slow crystallisation of magma below the earth's
surface, and is composed mainly of quartz and feldspar with minor amounts of
mica, amphiboles, and other minerals. This mineral composition usually gives
granite a red, pink, gray, or white colour with dark mineral grains visible
throughout the rock.
comes from numerous countries but mainly Italy, Norway, Brazil or India and
arrives in a slabs of approximately two metres by three metres.
of Yosemite National Park, in California’s Sierra Nevada mountains, is dominated
by granite, while closer to home Aberdeen is known as the Granite City thanks
to many of its building from the mid-18th to mid-20th centuries being built
from locally quarried grey granite, which can sparkle like silver because of
its high mica content.
Granite is found
close enough to the surface that it can be cut from shallow quarries, and in order
to get it into transportable blocks small holes are drilled in the shape of the
desired block size. Carefully planned explosives placed into these holes create
just enough blast to separate the block of granite from the bedrock without
breaking the block itself which, if everything goes to plan, lands on a bed of
soft sand so that it doesn’t crack or split at a bad angle.
raw blocks are then transported to the quarry’s onsite fabrication facility to
be cut into slabs of either 2cm or 3cm thick using giant circular saws or with wire
blades that are not unlike an egg slicer; and it can take up to an hour for
these blades to go through 30cm of stone.
Once the cutting
is done, the surfaces must be polished to bring out the natural colours and
patterns and make them smooth to the touch and this is done by running the
slabs horizontally through polishing machines.
machines have large, diamond polishing pads that slowly bring out the shine in
the stone with each new layer of polishing. Much like wood, granite much be
polished with progressively finer pads to get a quality finish, and this
process just polishes the top surface of the stone leaving the slabs with rough
slabs are polished, they are put into bundles of six or seven slabs and almost
always in the order that they were cut from the block to create batches that
have consistent patterning and colour. After that they are put in a shipping container
bound for the UK where they are distributed to natural stone specialists such
our job to “fine tune” whichever piece of granite has been chosen by the
purchaser. We ensure that the correct template is made for the granite to be
machined to fit into your new kitchen; and in our manufacturing facility our
technicians get busy with the latest in computer aided design to plan out the
best way to cut each unique slab to make the most of its pattern and size.
combination of our three automatic
Terzago saws, waterjet CNC machines and an automated polishing line we trim the
granite to size before stone routing machines cut and polish custom edges.
this process is complete, our skilled technicians inspect each piece making hand-polishing
finishes and finalising any details that could not be crafted by the machine. After
all of that, the granite worktop is loaded onto one of our trucks for delivery
