Granite is generally more heat-resistant than Silestone. Both granite and Silestone (a brand of engineered quartz) are popular choices for countertops, but they have different properties when it comes to heat resistance.
Granite is a natural stone formed under high heat and pressure, which gives it excellent heat-resistant properties. It can withstand high temperatures, such as hot pots and pans directly from the stove or oven, without being damaged or discolored. However, it's still a good practice to use trivets or hot pads to protect the sealer and avoid potential thermal shock.
On the other hand, Silestone is made up of a combination of natural quartz crystals and resin binders. While it is durable and resistant to many household chemicals, it is not as heat-resistant as granite. Exposing Silestone to high temperatures or placing hot objects directly on the surface can cause thermal shock and lead to discoloration, cracking, or damage to the resin.
To maintain the quality and appearance of both granite and Silestone countertops, it's essential to use heat-resistant pads or trivets when placing hot items on the surface, even though granite can handle heat better than Silestone. Always check the manufacturer's guidelines and recommendations for proper care and maintenance of your specific countertop material.
