Is granite fire resistant?

This blog post will answer the question, “Is granite fire-resistant” and cover topics like the fire-resistant properties of granite and frequently asked questions related to the topic.

Is granite fire resistant?

Yes, granite is fire resistant. It can withstand extreme heat.

What exactly is granite?

Granite is the most abundant intrusive rock in the earth’s lithosphere, and it is best known for its mottled pinkish, gray, and black decorative stone. It has a rough to medium-grained texture. 

Feldspar, mica, and quartz are its three primary minerals, which may be found as silvery muscovite, dark biotite, or both. Feldspar is the most common mineral, with quartz accounting for more than 10percent of the total. 

Because alkali feldspars are frequently pink, pink granite is frequently utilized as an ornamental stone. 

Granite is formed by the crystallization of silica-rich magmas deep inside the Earth’s crust. From the hydrothermal fluids released by crystallizing granite rocks, several mineral deposits emerge.

What Effects Do Extreme Temps Have on Granite?

It is not affected by extreme heat. Granite is one of the most durable countertop materials available, and it may last a lifetime if properly cared for. 

You may assume that removing pans from the stove and placing them on your granite counters is safe – after all, how can a 351-degree pie plate harm rock that was once molten lava? The fact is that it isn’t possible. 

Your granite will be fine on its own. However, since granite is somewhat porous, it must be covered with a non-volcanic, man-made sealer to avoid stains and produce an easily cleanable, disinfectable surface. 

As a consequence, overheating the sealant may result in complications.

Is it true that heat may harm granite countertops?

Granite is among the most long-lasting kitchen countertop materials available. Under normal conditions, the heat from a hot skillet or pot will not harm a granite surface.

Mineral hardness is measured using the Mohs scale. On the Measurement of Hardness scale, granite is a 6 on the scale. 

The toughness and density of granite materials are indicated by this rating. Diamond is the hardest mineral discovered in nature, with a hardness of 10.

The Process of Granite Formation

Granite is an igneous stone that is formed by a process of tremendous heat followed by cooling to produce tough and solid granite. Granite has a unique resilience to heat harm due to the way it is formed. Even when exposed to direct heat, granite will not melt.

Please keep in mind that Granite has a melting point of 2210o to 2300o F, while you grill your steak at 350o to 450oF. 

When you consider that steel melts at 2498 degrees Fahrenheit (1370 degrees Celsius), you may feel more at ease with granite’s heat resistance characteristics.

The Heat Resistance of Granite

Granite will not be harmed by heat. Even if the pan is placed directly on the granite counter, a hot pan up to 1,200 °F will not harm it. A source of tremendous heat over a sustained length of time might harm the surface of the granite. 

In the worst-case situation, the harm would be a minor weakening of the granite, which might lead to staining or gouges.

Normal kitchen operations such as baking in the microwave and cooking on the stove will not create hot enough pans or pots to harm granite, but the hot pots may remove the sealant layer from the surface, leaving it prone to future stains.

The heat is drawn away from the goods by granite. This implies that putting a hot casserole dish on a granite countertop will cause it to cool faster since the granite absorbs heat from the hot dish. However, granite countertops are not recommended for this use.

Heat coasters should be used to set hot pots or plates on the kitchen counters.

What Effects Do Extreme Temp Changes Have on Granite?

Granite may be damaged by extreme temp variations if it is exposed to them directly.

There is a chance of harm to granite countertops if they are used in outdoor kitchens that are subjected to heavy heat in the summer and high cold in the winter. 

The great news is that there are several really high-density granites on the market that can survive the rigors of outdoor use. For outside kitchens, granites that can tolerate harsh weather should be chosen.

Granite’s advantages and disadvantages

When it comes to selecting a kitchen countertop surface, there are several aspects to consider. Whether granite has reached the top of your list, read the following article to see if its benefits and drawbacks make it a viable option for your kitchen.

  • Sustainability.
  • Heat Resistance.
  • Scratch Resistance.
  • Seams.
  • Undermount Sinks.
  • Crack
  • Sealing
  • Maintenance
  • Price
  • Exotic Options.

I will now elaborate on the guidance given above.


Did you know that over the course of many centuries, a single quarry site may provide stone for hundreds of residential projects? In its natural condition, granite is also almost perfect as a countertop material. 

Once mined, it just requires little processing to be ready for use in your kitchen. Engineered materials, on the other hand, have a complex manufacturing process that often involves toxic substances and detrimental emissions into the environment.

Heat Resistance.

When subjected to heat, granite will not melt or blister. They’re one of the most heat-resistant surfaces available. Hot dishes from the oven may be put straight on the counter surface without causing damage. 

When utilizing appliances that release heat for extended periods of time, such as Crockpots, experts suggest using a trivet.

Scratch Resistance.

On the Mohs scale of mineral hardness, granite has a 7. This implies that only a small number of minerals may scratch it. While cutting on granite is possible, it is not advised since it can dull your blades and may leave a metallic residue that is hard to remove.


Granite countertops in a normal kitchen will need 2-3 seams. The typical slab size may vary depending on the hue of granite you pick. The standard size for a room is 9 feet by 5 feet. 

Large islands are usually constructed without seams. Expect seams where the counters curve in a different way if you have an L or U-shaped arrangement. 

The great news is that several fabricators will create custom hue epoxy to bind the seams together, making them almost undetectable. The seam should be around 1/8″ thick.

Undermount Sinks.

In granite countertop installations, undermount sinks are typical. Crumbs and spills may now be wiped straight into the sink instead of getting stuck on the edge of a surface mount sink. 

Several varieties of sinks are available, including stainless steel, and solid surface. The sinkhole will be cut and polished to fit the form of your selected sink.


If you see a crack or fracture in your countertops, contact the fabricator who placed them to arrange a repair appointment. In most cases, a color-matched epoxy may be used to cover the gap and will be nearly undetectable. 

In a pinch, superglue may be used to fill chips. If you’re using large cast iron cookware, exercise caution while putting them in an undermount sink. 

The most typical location for chips is around the cutout’s edge. However, a rise in the number of damaged dishes is a more plausible situation.


Granite is a porous substance, but this isn’t always a negative thing. Liquids that have been left on the surface for an extended length of time will ultimately absorb. 

They will, however, vanish exactly as they absorb. You may use various poultices to speed up the procedure depending on the material that has to be eliminated. 

Many, on the other hand, will dissipate without the need for solvents or cleaning agents. Before installing granite countertops, many fabricators will use a sealer to prevent them from soaking liquids too rapidly.


Granite is said to be a low-maintenance countertop material. It is unlikely that it will need to be fixed or resurfaced. Sealer technology has advanced significantly over the years, and most will survive for more than ten years before having to be reapplied. 

When they do need to be renewed, most homeowners may do it themselves by simply applying the product and wiping away the excess. It’s a great idea to ask your dealer which sealer was used the first time and reapply the same one.


Granite countertops in a normal kitchen cost between $3,000 and $4,000 on average. Corner profiles, overall square footage, and backsplash are all variables. 

Don’t be deceived by the common misconception that granite is all pricey. Granites in the lower price range will be less expensive than laminate in the higher price level. 

Though granite counters are not considered ‘low-cost,’ there are a number of economical choices starting at $30-$55 per square foot. When comparing prices from multiple businesses, be cautious. 

Make sure you’re comparing apples with apples in your comparisons. Material, construction, and installation should all be included in your final quotation.

Exotic Options.

Consider unusual granite if you want something genuinely one-of-a-kind. Price is decided by supply and demand, as it is with most things in life. 

Some quarries are difficult to reach or can only be mined for a limited amount of time each year. If these conditions occur at a quarry containing one-of-a-kind stone, the price will go up. Some granites have a price per square foot of above $400.
