No, you should not put a hot pan or pot directly on a quartz countertop. While quartz is generally heat-resistant, the resin binders used in its manufacturing are sensitive to extreme heat. Placing a hot pan on the surface can damage the resin, leading to discoloration or other cosmetic issues. If the heat exceeds 150 degrees Fahrenheit, it can cause permanent damage, such as burns or even cracking. To protect your countertop, always use trivets or hot pads.

The frequency for sealing granite countertops depends on several factors, including the type of sealant used, the color of the granite, and how heavily the countertops are used. As a general guideline, resealing is often recommended every 12 to 18 months, but some sources suggest it could be as often as every few months or at least once a year.

The type of sealant is a major factor: water-based sealants may need reapplication every six months to a year, while more durable solvent-based sealants can last for five to 10 years. Additionally, factors like heavy kitchen traffic, frequent use of acidic cleaners, and lighter granite colors may require more frequent sealing to prevent staining.

To determine if your countertops need resealing, you can perform a simple water test. Place a few drops of water or a wet paper towel on an inconspicuous area of the granite. After 10 to 15 minutes, check the spot. If the water has beaded up, the seal is still intact. If the water has been absorbed and darkened the stone, it's time to apply a new coat of sealant. You can choose to seal the granite yourself or hire a professional to ensure it's done correctly.

Marble countertops don’t necessarily crack easily. However, they are more susceptible to damage than some other types of countertops. For example, they can develop etching from acidic liquids, such as lemon or tomato juice. Marble can also chip at the edges if you drop a heavy pan. A faux marble countertop isn’t as delicate as the real deal (depending on the material you’re painting over), but it can still get scratched if you’re not careful. Use hot pads and cutting boards to protect the countertop.

For most homeowners, quartz and quartzite countertops are similar in price. The average quartz countertop installation costs $80 to $220 per square foot, while quartz countertops cost $70 to $200 per square foot. Of course, there are outliers, like if you choose a highly customized, rare natural stone with high-end finishes.
