How Much Heat Can Granite Take?

I just got a new egg table with a granite top. I was wondering how much heat the granite can handle.  For example, can I put a hot platesetter/woo/AR/etc. on the granite without damaging it?

The granite I have is SenSa Floresta Verde (apparently discontinued). Their website says it can handle temps above 300 C (572 F), and many times the items will be hotter than that.

Perhaps I can make a landing zone with something that can handle more heat?

Open to any suggestions. Thanks!

    I have a 1.5" granite slab on my challenger cart. I put it on there all the time. Now the grease drippings do leave marks.

    The granite will take the heat, but would you really want to mark up a nice granite top with your plate setter?

    @HofstraJet   I used a piece of granite as a pizza stone for years.  It can take the heat.  However, if I had your table, I'd have a sacrificial piece on top on some rubber feet as my "dirty counter".

    I looked at the website. Seems itts not the granite that is at hazard from the heat, it is the stain resist treatment. Maybe buy some ceramic blanket or fiber board as a hot pad. Folded up welding blanket seems like it might work.

    I think that the risk is too great. An unseen void or vein that causes expansion differently and pop you have a ruined piece of granite.  A huge cost to replace.  It might be okay over 99% of the slab but that one spot you can't even see could cause irreparable damage.

    I use a granite landscape paver for a landing pad (pictured just to the right of my grill gripper). It's about 2 1/2" thick and about 6x6" square. It's plenty thick to take some heat and lets enough air get to the plate setter or other indirect piece to let it cool pretty quickly. I also use it to prop up tongs or spatulas to stay clean when I'm tending the cook. It also keeps the table a little cleaner and can be easily washed up when it's as dirty as shown.

    Not all granite is the same. It will have quarts and Mica and all kinds of minerals mixed into it. Something 350-400 might be fine. Hotter and I'd rather have something on it like a hot pad or cooling rack to keep it out of direct contact.

    Do you have any left over floor tiles gathering dust somewhere?

    I bought a metal trivet at Ikea, 15 years ago, it has taken everything I've put on it, including my PS at 600º dome. I think it was $5.

    Not sure how nobody mentioned burning off the sealant on the granite? I would be more worried about that than the granite itself.

    I am curious, what are you doing that you will have items hotter than 572º on the table top?  I can see pizza and naan bread cooking at high temps, but don't see a need to deconstruct the stone setup during those cooks.

    In cooking, often we implement steps for which we have no explanations other than ‘that’s what everybody else does’ or ‘that’s what I have been told.’  Dare to think for yourself.

    Get a piece of extra granite or even a big ceramic tile from Home Depot just in case. I agree with what @Toxarch said. And get this for the sealant. You can get it at Amazon.

    Best stuff hands down. It's good for everything. Granite and all types of stone, stainless steel, wood, glass, tile, just don't put it on your floors...slicker than owl sh*t. I've been using this on my outdoor kitchen (and everything indoors) for years. Still not one stain on my outdoor granite. Even after grease spills etc. No, I'm not paid by them and I don't work there...

    $19 shipped from Amazon for the Bee's Wax polish. Shipping is too high.

    Yeah - that's a good point. I was thinking of hot platesetters, but I would be putting a PS there before searing, so the PS would be at around 300 or so as it would come from the indirect phase.

    I think out of an abundance of caution I will get a spare piece of granite or big thick tile just so I don't run the risk of ruining the tabletop. Thanks everyone.

    If you're going to get a floor tile, you might be interested in adding some rubber feet ... provides additional heat protection and scratch protection.  I had an 18" tile for about a year, then switched to a 24" tile in February.  Contrary to concerns, neither of them cracked from heat or weight.
