Heat Resistance: Quartz and Granite. Granite fully melts at approximately 2400 degrees F (an unlikely home temperature scenario). It also does not support combustion, nor does it crack or discolor when objects are placed onto its surface. Although quartz counters do not technically melt, low cost versions can sag or warp when subjected to heat. Most tend to discolor due to resin burn, should any hot object (typcally over 150 degrees F) be placed directly onto their surface (such as a hot pot, pan, or dish). Such damage is NOT repairable. For mid-to-high priced quartz formulations with higher temperature resins and very high ratios of solids to resin (make sure to ask if there is a temperature rating), the burn point can be up to 440 degrees F. However, the reduced quantity of resin can result in deep cracking if hot objects are placed onto their surfaces- especially near sink cutouts or edges. This type of damage is also NOT repairable. Our advice is to simply avoid placing any hot items directly onto either quartz or granite countertops. There's no reason to take a chance on damaging the surface of a quartz counter, or to burn yourself by leaving a hot spot on a granite surface!
