Granite is an extremely impressive stone. Granite is tough, stain and scratch resistant and can handle some serious heat. Granite can withstand temperatures up to 900 degrees Fahrenheit (482.22 degrees Celsius) without causing damage. Experts will tell you that cutting on your counters won’t hurt the countertops at all, it will only dull your knives. Short of trying to cut your granite with a diamond or, more dramatically, smashing it with a sledge hammer, it will not break or even crack. These statements are just some of the evidence available that will prove that you’re granite countertops can last a lifetime.
