The problem with quartz on the backsplash is mostly the area behind a range. Most of the damage is from the heat coming out of the rear vent of the range when roasting at high temps or running the self-clean cycle.

If you bought a range that has the option of ordering with a stainless backsplash, you can then do the quartz elsewhere.

Heat from high frying in the back burner could also be an issue.

See the vent in the back, that is usually what causes the scorching.

Here are the type of risers that might be available with the range you are considering.

Another option is to pull out that whole cabinet run, so you have a lot more space behind your range. You don't see this often because most people don't have the space in their kitchens.

Well I am not sure if this helps but I will have an induction cooktop not gas, still splashes will occure when frying but not flames close to the backsplash.

Quartz can be used behind range/cooktop as long as you follow the range/cooktop installation guide and adhere to the clearances. Most issues with quartz occur with ranges that vent out the top back. Not only can it scorch but it can crack. Also be aware that heat resistant does not mean you can set a hot pot right on the counter.

Most induction ranges vent the oven out of the back -- it's the heat from the ovens, not the flames on the top, that cause the damage.

I think all materials have their needs for upkeep, and it's not realistic to expect any material to never change or get damaged as we live with it.

The quartz manufacturers and vendors are kinda talking out both sides of their mouth with the marketing. It's heat resistant! But always used coasters and trivets. It's durable and the look lasts forever! But it changes color in the sun. It's scratch resistant! But don't scrub too hard or you'll need a professional to restore it. Etc.

We have had hot oil splashes as well as lemon juice, turmeric, and coffee and nothing has stained our quartz. It does have two small chips but my understanding is that a sharp edge profile is to blame for that.

Since we have a tile backsplash can’t comment on that. Although we use trivits some quite hot pans have found there way onto the countertop without damage so its not too wimpy.

You might want to compare solid surface countertops. They definitely are non-porous, will not stain and any scratches can be easily buffed out. I got a matte finish plain solid white but it comes in many colors and patterns. Corian is the most well known, but there are many other brands. I used LX HiMacs Arctic White and had an excellent fabricator, which is important with any countertop material.

Quartz is not heat resistant. Quartz slabs are factory made. They contain crushed quartz particles, 33.5% plastic resins by volume, and dyes. It’s the resins that melt when coming into contact with heat.

If you have an oven/stove, the oven’s heat exhausts out of the top rear vent. That’s what will scorch and damage a quartz backsplash. Doesn’t matter whether the unit has a gas or induction cooking surface.

To mitigate the issue, have the builder install a fireproof wall behind the stove. That is, steel studs…not wood, with cement board in front of the steel studs. My contractor did this in our kitchen, even though we have a rangetop with separate wall ovens…and have ceramic subway tiles behind the rangetop.

To be especially safe, use a sheet of stainless steel behind the oven…as others have suggested.

Be forewarned. Quartz counters can be damaged by simply placing the lid from a hot pot, directly onto the counter. There were some threads a while back, where a family member did that, and left burn marks on the counter. You must always use trivets with quartz.

ok then some manufacture just lie about their quartz's heat resistant properties ? https://www.caesarstoneus.com/blog/how-heat-resistant-is-quartz-countertop/

Yeah, it says in there 150 (I presume F since it's the US site). Cooking involves much higher temps than that!

Did you read that link?

They tell you exactly how "heat resistant" it is. I drink my tea hotter than the temp they list as "high heat" for their quartz.

Everyone will have a different definition of "high heat".

I don't see where they are lying?

"Quartz countertops are heat resistant. But how much heat can it take?

Are quartz countertops heat resistant? Yes but not heat proof!

While a quartz countertop is heat resistant, it can be damaged if exposed to too much heat.

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.

Mistakes happen, so you may place a hot pan on your quartz countertop and see immediate scorch marks on your countertop, usually brown or yellow. This does not mean that the countertop is completely ruined. It is an indication of a resin burn, which professionals can usually – though not always – repair.

You may also notice that moderately hot pans and pots may cause discoloration on your quartz countertop if left on the surface for long periods, which is why a hot pad or trivet should be used."

This is true for all quartz brands.

I would never place a truly hot pan off the stove, or out of the oven, on any counter.

That is why trivets were invented!

I have Taj Mahal quartzite, a natural stone, that is very durable and probably quite heat resistant, but I would never take a chance with hot items. Stone counters can also be affected by thermal shock, which will crack the stone. Yes, a rare occurrence, but not worth taking a gamble and then having to spend thousands of dollars replacing the counters. If I couldn't find a matching slab for a repair, I would then have to spend $20K+ to replace all the counters. Using a trivet is so much easier!

Where is the lie?

I suggest getting samples of the exact material you are considering, and testing it yourself. Keeping in mind that not all quartz is the same, like not all stone, etc is the same.

Take a very hot pot right off the burner and set it on the sample. Whack the sample with the pot, cut on it with a serrated knife, leave nasty stuff on it overnight, basically do your worst. Then see how easy or hard it is to fix the damage.

There are so many threads asking if this or that material is going to stain, scorch, chip, scratch, etc. Nothing is 100% impervious. Everything will stain, scorch, chip, scratch, etc. You need to figure out what it will take to do it, and how that compares with how you and your kids, “helpful” guests, absent-minded Aunt Millie, will treat the material. Not when it is brand new, but after a year when you’ve gotten careless.

Best to figure it out with the actual material you have in mind.
