Stone Processing
Stone is a tactile and
versatile material and it is an exciting experience to watch finished
stone emerge in multiferous forms from a piece of rock. The processing
of natural stone starts at the quarry where a section of solid rock is
found and blocks are separated from it with as little damage to the
stone as possible.
Heavy equipments are used to transport the blocks of stone from the
quarry to the processing yard where they are sawed into tiles, slabs.
Secondary sawing reduces the slabs into dimensional masonry. More
intricate work can be carried out on profiling saws and planing and
polishing machines and of course by hand. Hand working of stone,
however, retains an essential place in the last stages of processing,
when highly skilled masons work the more detailed stones to their
finished form.
Sophisticated methods bring better results than brute force and modern
technology can be applied. The aim of using latest technology programs
is to make the sector more internationally oriented and to solve the
problems of quarrying and processing so that the material which is of
high quality and needs little care could be more widely used in
buildings and other construction works. The natural surfaced blocks are
cut into pieces of varying thickness and sizes, as required. The surface
is then given the required textures with different finishes.
Honed or polished surfaces are achieved by grinding the cut face with
successively finer grades of abrasives. Sandstone and limestone are
often available in honed finish. Marble and other harder limestones can
be polished. To achieve the true color and pattern of natural stone,
polished surface is the most popular among different types of stone
surfaces as it does not change the nature of the stone.
