Granites are found deep inside the earth's crust and thus the place where the mining of granites takes place is called "QUARRY". Blasting of dynamites, use of drilling machines and huge JCBs are very common while extracting the granite blocks from those Quarries. It takes very strict supervision, policies and regulations to extract the blocks as it is one of the most injury-prone step while manufacturing granites. Brave employees work day and night keeping different measure of precaution in account. After the blocks of those granites are extracted they are read, examined and measured before they are shipped to the manufacturing plants.
After the granite blocks are shipped to the manufacturing plants; blocks are re-measured, the second step is to figure out or examine the flaws in the block and clean them away by cutting the flawed part of the block. Flaws in the block can be either a crack (also referred to as lines), patch (a discolored area in a block).
After chipping is done, supervisor of the manufacturing plant belonging to blades and cutting department will now use some math's calculation and then figure out about how to cut the granite slabs from the block to have more extraction and less waste. In other words, its supervisor's job to see and plan the ways on how to cut the slab from the granite block to have more clean and bold slabs. After getting the knowledge on this, granite blocks are then laid below the heavy blade machines which then cut those slabs in the desired thickness and height.
After cutting the slabs from the granite blocks, those slabs are then sent to the grinding and polishing department for the further process. Slabs are laid under the heavy hydraulic press with the rotators at the edge. Those rotators have grinding panel attached to them and those rotators spins over the slabs so that the fifth step, epoxying can be processed.
Desired color epoxy is then applied over one side of the granite slab. Epoxy varies from color to color. For e.g.: for black granites, black epoxy is used whereas for red granites, red epoxy is used and for few granites like sadarahalli, transparent epoxy or in other words, colorless epoxy is used. After applying those epoxies granite slabs should be dried so as to let the raw granite slabs absorb the color of the epoxy.
NOTE: Epoxy is applied over granites to have two specific touch namely;
i. Glossy Finish (it gives a shiny and smooth texture feeling)
ii. La potra Finish (it gives shiny and leather texture feeling)
Epoxy is not applied over granites to have two specific genres namely;
i. Hund (Only the grinding is done and the granite slab is ready to decorate the floors, stair case, etc.)
ii. Flamed (after grinding, slabs are exposed to high tensile flame to give a rough surficial touch which can be then used in garden flooring or outdoor flooring.
After epoxying, granite slabs are again sent to grinding and polishing department for the further process. Slabs are laid under the heavy hydraulic press with the rotators at the edge. Those rotators have polishing panel attached to them and those rotators spins over the slabs so that the granite is shiny and glossy. The panels vary. To give slabs La Potra finish, the panels are different and to give slabs Glossy finish, the panels are different.
This is how those natural ornaments known as Granites are manufactured and are now ready to decorate your home, office, lawns, schools, etc.
