Why Granite Cracks

 In this section we should first question that can granite cracks?  Granite does not crack under ordinary and common use.  Granite is most susceptible to cracks during transporting, fabrication and installation.  Granite stone won't flex like laminate and solid surface tops.  Do not stand on or next to the sink, cooktop cutouts, or unsupported overhangs because too much stress or weight may cause this stone to crack.
Granite is really quite strong as a counter surface. It doesn't stain easily and in fact most granite stones will not stain at all. Because granite is all stone and not particularly hydroscopic, takes a great deal of heat, certainly the temperature of a hot pot out of the oven or off the stove top isn't enough heat to cause thermal expansion and cracks. If you do not install it fit tingly, that is supported well around the edges, it could crack and will be break because of extra weight or pounding, this problem will also depend upon the thickness you had installed, apparently the thicker the stone the more abuse it can tolerate in that regard.
Many exotic kinds of granite have fishers in them that are filled with resin and a ground stone mixture; these are typically mounted on a hole backing which allows for the use of such stones in a kitchen or bath at home. These would be the most likely to be weak and fragile, but even these are very strong.

Granite Breakage, Fissures &Cracking

Granite stone is repairable, but the repairs can easily be seen.  One seminar at a surfaces show indicated and advocated misleading the customer.  The seminar teacher said to finish up the repair while the homeowner was out of the room, then commence polishing a different area so that when the consumer enters the room, you should point to the spot you were polishing on and ask if it was good enough! (This is a very unfair deal) How do I care for my granite stone in the kitchen?  A mild neutral cleansing agent like dish soap is fine for cleaning granite from stains.  Do not utilize acidic, harsh antibacterial cleansing agents, citrus cleaners and whiten detergents on your granite.  These cleaners can etch the finish and dim the stone over time.  Wipe up spills as they occur not so long time after it happens.  Sealing granite every six months and from time to time using a good commercial cleaner / polish made specifically for granite is a good practice to save the granite stone from dimming, stains and cracking.
There are natural Fissures, that is to say narrow openings in the stone that look like cracks on it. They are not structural defects and will not weaken the function or durability of the stone.
Real cracks occur when extra weight is applied on top of the stone at narrower areas such as around the sink or an overhang. Even though cracks can happen during install, once secured and glued down the crack will never cause additional future problems.
Cracks may also occur from behind the stone unsightly though. When caulking or epoxy wears or deteriorates around the sink or back splash, this allows water encroachment under the stone. Water intrusion can result in the adhesive to breakdown and the sub-top to swell causing the stone to break.
Now is the turn to ask if granite can be cracked? The answer is: not with regular use. Granite is most susceptible to cracks during transferring and installation. Normal use will not overstress this durable and robust stone.
Granite countertops can crack like most stone products,. However, this may require a great deal of force, usually the kind associated with a large falling body. Most granite countertops are guaranteed for more than twenty years, and except a major disaster such as an earthquake or similar natural disaster, a granite countertop must last as long as the home in which it is installed.
Due to natural calamity
If you live in the part of the country that is tending to tornadoes, hurricanes or floods, your granite countertop stone is in danger. Tornadoes and hurricanes can pick up debris, creating projectiles or missiles that can smash into a granite countertop. Tornado winds have been clocked at over 150 miles per hour in some parts of the country, and these winds can easily change rocks and huge stones and even trees into deadly bullets. While a granite countertop that gets through with these projectiles is not likely to be smashed to bits after one impact or touch or influence, repeated impact can wear away at the countertop, finally causing it to crack.

If you live on a geological fault line, you are equally at risk of cracking your granite countertop. Falling debris and lumber from your home or establishment will most likely and prone to land on your countertop. If enough weight gathers on the counter's surface, it is certain to crack.
Due to surround all sides'heat
Although granite is an igneous rock and is highly resistant to heat, constantly abandoning a granite countertop to heat will damage it, and can cause it to crack over time. Usually, people with granite countertops in their kitchen take pans right off the fire, and put them on their countertop. Finally, a countertop which is treated this way will crack, or at the very least, develop pan burns on its surface.
Wearing and tearing
Having a 90-year old granite countertop may seem improbable, but it is possible. These products are famous for their durability and strength. However, counters that are this old will probably be very worn, due to gathered wear and tear. Constantly rubbing against items and skin will decrease the protective finishing of a granite countertop. Finally, the nonporous surface may give way to the rock core, which can ingest water and erode.

Warranty and maintenance information

Most granite countertops come to the market with two different warranties. One of them covers the finish of the granite countertop, while the other ensures its structural unity. Usually, the one covering the finish of the countertop is meaningfully shorter. Neglecting to follow the care and maintenance tips that the producers provide may void these warranties.
Ordinarily, one of these maintenance tips is using non acidic cleaning agents or detergents. These can quickly eat away a granite countertop's shiny surface. Granite countertops do not require exotic cleaning agents, and usually wiping them down with a wet cloth is sufficient and enough to clean them. Also, owners are insisted on using heating pads or trivets for hot pans. Eventually, using a cutting board for food preparation saves the countertop from unnecessary wears.
