“Heatproof” countertops

 

Countertop

To my dismay, I read in a Professional Builder magazine this morning that quartz countertops were “heatproof”, suggesting that you can place your pots and pans directly on the countertop.

“A quartz countertop provides an attractive and hardy work surface that’s also a heatproof landing for hot pots and pans on either side of the cooktop.” 

This is misleading and simply not true.  Check the product information of any of the quartz countertop manufacturers (Silestone, Cambria, etc.) and you will find explicit warnings not to place hot pots and pans directly on the quartz surface as this can result in thermal shock.
The same is true for granite.  Even laminate and solid surface products are not heatproof.  While you may have done it in the past without dramatic results like thermal shock, scorching, cracking, or de-lamination, placing hot pots and pans on any of these surfaces will void your warranty.
Protect your investment and use a trivet.
