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. If you were to put such high heat on quartz, the resin is very likely to burn and the countertop's coloration would be significantly impacted.
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.
Your coffee pot, a bowl of soup, or mug of hot tea won't damage quartz surfaces.
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.
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.
Crockpots are not going to injure, stain or burn your quartz countertop. Most crockpots have legs or stands, and if you take the inner crockpot out and rest it on the table top, as long as it's not over 400-425 degrees, you are safe.
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.
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.
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.
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.
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.
If the scorch marks don't budge, smear a paste of baking soda and water on the affected area and let it sit there for a few minutes. Wipe off the paste and lightly scrub the surface to remove the marks. If the burn mark is severe you may require specialist heat damage repair.
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.
Dwyer quartz countertops are some of the most wear-resistant on the market. They are also heat, stain, impact, and scratch resistant.
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.
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.
Windex is considered a base and has a pretty high pH level, which means it could be damaging to quartz. Some cleaners say it's okay to use in small quantities, while others warn against it. For the safest and most sure option to keeping your quartz clean, skip Windex and opt for a mild cleaner like dish soap.
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.
Overall, quartz has a strong heat resistance and won't change shape or color when exposed to routine heat. Still, excessive and prolonged countertop heat can damage quartz, so you'll want to use a trivet or pad between the countertop and any hot cookware or heat source, such as electric frying pans or curling irons.
