Processing Granite — From earth to kitchen.
By · CommentsGranite counter top process.
Getting granite countertops installed in your home is a relatively simple process when looked at from the perspective of what you as the consumer can see from beginning to end. Simply put, you call us, select your slabs, & agree on the particulars, then a couple of weeks later they are installed.
There is however a lengthy process involved in getting the stone from its natural state in the earth all the way to your kitchen countertop.
The process of turning stone into decorative and functional building materials has been more or less the same for centuries. On the other hand, the equipment has changed dramatically in that time, and the production time greatly reduced.
The process starts at the stone quarry where large blocks are cut from the earth often in a stair step like pattern. Various types of sawing & cutting methods are used. There are wire saws which are long steel cables with diamond sections embedded in them. These cables are passed through “core holes” which have been drilled horizontally and vertically to a meeting point in the invisible corner of the “bench” to be removed. Then the cable is run through a drive, continuously going deeper into the stone.
Core drilling, as mentioned above, coupled with “blasting” is another method of freeing large blocks of stone in this first step of the process. Some quarries use expanding liquid rather than explosives in the core holes—this is for the more fragile stone to keep from fracturing the blocks. Read More→
