GRANITE

                                                                                    GRANITE
The word “ Granite” comes from the Latin granum, a grain, in reference to the coarse- grained structure of such a holocrystalline rock. Granite is nearly always massive, hard and tough.
Granites are also an increasingly popular choice for practical and hard-wearing surfaces in today’s home. They make wonderful kitchen countertops and tiles for floors and walls.
Brihadeeshwar temple stand amidst fortified walls that were, it is Said, added to the temple complex
That Temple is made up of about 1,30,000 tons of granites.
Brihadeeshwar temple was completed in 1003 CE.

Brihadeeswarar Temple is first among all buildings, which make use of granite fully and it finished within five years from 1004 AD to 1009 AD.
The Peruvudaiyar Kovil is a Hindu temple dedicated toShiva, at Thanjavur in the Indian state of Tamil Nadu. It is an important example of Tamil architecture achieved during the Chola dynasty. It is also known as Periya Kovil, Brihadeshwara Temple, RajaRajeswaraTemple and Rajarajeswaram, The temple is part of the UNESCO World Heritage Site known as the “Great Living Chola Temples”.

PROCESS:

                Dressing

               Cutting/Sawing

                Surface  Grinding and Polishing

                Edge Cutting Trimming

Dressing:

Stone dressing: once a block of granite has been broken down to the appropriate size required, the sides have to be roughly smoothed off before polishing can begin. Stone dressing was usually carried out at stone-cutting and polishing works, rather than at the quarry itself.

Originally, rough dressing was done with a blocking hammer or a dressing pick, with puncheons and chisels for finer work. A more efficient dressing tool was the bush hammer, or patent axe.

Cutting/Sawing:
The rough blocks arriving at the stone yard from the quarry are irregular in size and shape is inspected to identify the most efficient way to cut them into slab from while minimizing wastage.

Once the initial inspection is complete, the block is primarily sawed into slab form by means of large circular diamond-tipped blades, wire or monoblade saws which cut one slab at a time or by a frame saw with multiple blades that cut each block – depending upon its size – in a single operation into a number of slabs.

Surface  Grinding and Polishing:

The polished granites tiles are packed in a systematic manner to avoid the breakage of tiles.   Then these are ready for export to national and international market.

There are no of workers working in the polishing factory.  The workers are divided on their work done, cutting men is separate one who has experience in cutting the blocks the polishing worker is been appointed separately for polishing the granite tiles.      The polishing process required high technique machineries for cutting and polishing.  The water is required in the cutting and sizing the granite tiles.

Edge Cutting Trimming:
