Homeowners don't need to worry about damaging their countertops with everyday use because granite is quite heat resistant. Placing a hot pan on a well-maintained granite slab will not cause it to crack or weaken. Just remember that repeatedly placing a very hot pan on the same spot may cause granite to discolor.
Granite is naturally heat resistant, and heat damage would occur only if the granite was heated unevenly. So briefly putting a hot pan down on your granite countertop isn't going to cause long-term damage. That said, we don't recommend putting hot pans on granite countertops — not for the granite's sake but for yours.
How to Protect Your Countertop. You can put hot pans on granite with no worries if you place something underneath them. A trivet, pad or potholder will absorb the heat from the pan before it reaches the surface, preventing damage to your countertop and preserving its beauty.
Use Trivets or Hot Pads for Hot Items
This is why it is so important to keep heat from coming in direct contact through the use of trivets, hot pads, or other types of pads creating a layer of protection between hot pans and countertops.
Granite is so heat resistant that you can place a hot dish directly on it without leaving marks or stains. When it comes to heat-resistant materials, quartz is your second-best bet. You can't easily scorch quartz, but you will want to use a hot pad before placing a dish directly on it, or you could damage the quartz.
Granite. One of the most heat-resistant options for kitchen countertops is granite. This natural stone is formed underground through a natural process incorporating high pressure and temperatures. Typically, the heat generated by cooking will not be high enough to cause damage.
Granite will resist damage from heat. A hot pan up to 1,200 degrees Fahrenheit will not damage granite, even if you place the pan directly onto the granite counter. An extreme heat source over an extended period could damage granite surface.
While granite itself is heat-resistant, it will need to be sealed. The products it can be sealed with can weaken with heat, thus cracking. That is why we recommend that you use trivets if you are going to put a hot pot or pan on a granite countertop.
In general, a granite top is fine to use an air fryer on, but if you were using it constantly you might want to consider a protective board under it just to be safe.
Silicone is an inexpensive yet effective way to protect your countertops from a hot dish fresh from the stove. Silicone has a low thermal conductivity, meaning that it transfers heat much slower than some other materials (like metal or glass), leading to excellent heat resistance.
If after a few minutes the water has soaked into the granite, then it's time to reseal the stone. DON'T: Use harsh or abrasive cleaners and sponges. Windex; acidic cleaners, like vinegar, lemon, lime; or anything with ammonia or bleach should be avoided.
Granite is a stone that's strong enough to support the weight of small appliances and cutting boards. However, it's prone to damage from sharp objects like knives. Avoid using your granite surface as a cutting board. This can cause chips, scratches, dings, and other damage.
Note: Some experts will recommend sealing granite countertops every “6-12 months” or “3-5 years”, but there is no hard and fast rule.
DO NOT put hot pots, pans or appliances such as toaster ovens and slow cookers directly on your counter top's. Such items can cause serious damage to your stone or quartz counter tops.
Your granite countertops are a beautiful and integral part of your home—they facilitate meal preparation, homework projects and more. Keeping your countertops functional and crack-free should be at the top of your list of things to do, so it's important that you don't stand or sit on them.
Spills are not the only way liquids can seep into the granite. Containers such as olive oil bottles are often hard to keep completely dry, and the layer of olive oil on the bottom of the bottle will discolor the granite with prolonged contact. Leave these types of containers on a shelf or in a cabinet.
Any typical oil will work, for example vegetable or olive oil. Apply a small amount of oil to a soft, clean cloth, and buff the granite using circular motions. Don't forget to polish the edges of your counter! Oil will give your granite a nice shine, and also help it repel water.
Placing hot appliances on the countertops
Even if your countertops are tough, heat from heat-producing appliances such as ovens can destroy them. So always work at preventing damage to the countertops as much as possible. You can easily do this by placing a barrier between the appliances and countertops.
Heat Resistant: Granite countertops will not melt, blister, nor change color when exposed to heat. Unlike Quartz, Granite is one of the most heat-resistant countertops on the market. If you take a hot pan out of the oven, you can place it directly on your countertop surface without any harm!
Even when subjected to a direct flame, granite holds its structure–of course, firing a blow torch at your countertop for any reason isn't recommended. Because of their high heat resistance, any realistic amount of heat applied to granite countertops in your kitchen will not cause them to chip or crack.
Typically, granite has higher heat resistance than quartz with the former up to 450 degrees and the latter up to 150 degrees. Despite these levels of heat resistance, both materials must not be in contact with hot objects for long hours as it stains and discolors its surface.
The only instance when cracking could happen is when temperatures rapidly change from one extreme to another. For instance, if someone placed an ice bucket on the countertop and then set down a boiling pot of water in the same spot without letting the granite warm up or cool down, it could potentially crack.
If the granite surface immediately takes in most of the water and develops a dark mark or ring, you need to seal it once every few months. If it takes a few minutes for your stone countertop to soak up all the water, you only need to seal it once every year or two.
Generally, quartz is less expensive than granite, but many factors influence the total price of a project. In this article, we'll look at the differences between natural granite stone and engineered quartz stone and the factors that affect pricing so you can determine which material is best for your design project.
