If you were to put a hot pan or pot on a quartz countertop, the countertop could become very damaged. Quartz is made up of mostly quartz mixed with resin. The resin in the quartz is highly affected by heat, and this is why placing a hot pan on quartz is so strongly discouraged.
Quartz countertops are made with up to 90% quartz. The rest of the material is pigments and resin. Since the resin can only withstand approximately 150 degrees, placing very hot materials such as a pan directly out of the oven will burn the countertop and cause permanent damage.
Unlike natural stone, Quartz countertops should not be exposed to hot pots and pans. A quartz countertop can withstand up to about 150 F before it takes damage. The most common result is a discolored ring on your countertop if a hot pan touches the quartz countertop surface.
In the Kitchen
Quartz countertops are stunning and versatile. They don't scratch easily and don't need to be resealed. When it comes to heat, proceeded with reasonable caution. Your coffee pot, a bowl of soup, or mug of hot tea won't damage quartz surfaces.
Do NOT use crock pots or electric skillets while in direct contact with your Quartz surfaces. Always place them on a trivet or cutting board to protect your countertop. As with any natural stone, certain exposure to heat may cause cracks due to thermal shock.
The low threshold makes quartz more likely to burn or break when in contact with heat. Therefore, you can put a hot mug of coffee on your countertop, but a searing hot pan or boiling pot of water could leave a burn mark.
Sudden changes in temperature can cause the Quartz to crack which is why high heat appliances used in the bathroom such as hair straighteners or curling wands must be placed on heat resistant mats- often sold with the product.
Harsh, abrasive cleaners, pads, and sponges should be avoided since they can permanently harm countertops. Scrubbing too hard can leave a dull surface or cause superficial scratches. Oven cleansers, grill cleaners, paint removers, dishwashing detergent, and other high pH cleaners should not be used on quartz surfaces.
However, whilst Quartz worktops are quite heat resistant - placing extremely hot saucepans right out of the oven on the worktop surface is not recommended. Instead, we recommend that you use a heat pad (or trivet) to avoid damaging your worktop.
Placing Hot Appliances on Your Countertop. While quartz may be highly heat-resistant, prolonged exposure will damage the resin causing it to discolor. Temperatures above 300° F can spell bad news for your countertop. Besides, sudden extreme changes in temperature may lead to slab cracking.
Once installed, you can expect your quartz countertops to withstand heat up to about 300 degrees Fahrenheit. If exposed to temperatures above this range, the resin binders within the quartz slab can change their chemical state — often impacting the color of the quartz.
The quartz itself can often withstand temperatures of up to 300 degrees, but you don't want to damage the resin coating either, as this can cause burn marks on your counters or even small cracks. Additionally, exposure to anything below freezing (32 degrees Celsius) can also crack quartz countertops.
Use Trivets and Mats
If you put hot objects such as pots or pans on the counter, it may break the fabricated quartz's seal and lead to an array of other problems. Make sure you protect the work surfaces by using trivets and mats under any hot object.
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 is often cited as the most durable natural countertop material and is known for resisting cracks and chips. However, as a manufactured material, quartz rates a bit higher on the hardness scale and is slightly more resistant to damage.
We mentioned that it is important that you use only gentle chemicals on your quartz countertops. Some of these include dish soap, Simple Green, Magic Eraser, denatured alcohol, Rug Doctor Cleaner, or Hope's Surface Cleaner.
Conclusion. Clorox wipes should never be used to clean your quartz countertops because the solution used in the wipes can potentially damage the surface. Instead, use warm water and mild soap, white vinegar and water or a quartz cleaner.
Avoid using both alkaline and acidic cleaner because they will break down the bonds between quartz and resin and cause long-term damage to the surface. Harsh and acidic cleaning agents such as vinegar, lime, lemon are going to erode the sealant of the countertops' surface over time.
This will dull the finish of your countertop. Chemicals such as drain cleaners, paint strippers, or products containing Hydrofluoric acid, Methylene chloride, or trichloroethylene will also discolor quartz countertops. You can use the same sponge and circular scrubbing motions as you would for cleaning water stains.
Generally, quartz can withstand heat up to around 250 degrees Fahrenheit or 120 degrees Celsius. Placing a cup of tea or coffee directly onto a quartz surface shouldn't present a problem. However, we'd recommend exercising caution and using coasters and hot pads if you plan on placing hot items on your quartz surface.
Installing or even repairing the countertops isn't cheap, so you should avoid risking standing on them. In addition to damaging the countertops when you stand on them, you also risk voiding the warranty.
Quartz is Easier to Maintain than Granite
This countertop achieves a high level of durability without any sealant. As opposed to Granite, which requires re-sealing each year to maintain a less superior guard against the common hot pan, spilled wine, and dirty hands. An easy to clean countertop is the new kitchen dream.
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.
Unfortunately, the polyester resin in quartz can be easily damaged by heat from the toaster oven, electric frying pan, oven, crock pot, or any other appliance that produces a lot of heat.
