Quartz vs. Quartzite Countertops | CounterTop Guides
The resin used in manufacturing quartz countertops is a plastic, so it is prone to melting in heat above 300 degrees Fahrenheit. Where quartz has an advantage over quartzite is that it is less prone to denting and chipping because it is more flexible. Both countertop materials can be scratched by sharp objects, and a cutting board should be used.
