You May Want to ask:
1,Can these be used inside the bottom of an air fryer?
Yes,It can withstand heat up to 464f
2,Have you ever use it in the microwave? Is it safe to use?
Yes. I've had one in the microwave since I received them months ago.
I keep one on the glass to protect it from accidentally dropping something that would break it.
It is also good for removing small hot bowls.
3,Can these mats be used inside a pot to cushion canning jars?
They are solid and heat cannot get through like it should. They make a product for an instant pot, a round silicon mat made to let heat go through it.
That would be a much better option for canning jars.
4,Can I put hot dishes or pot/pan on it? It is really heat resistant?
Yes, I take things out of the oven using these daily. I have taken pots right off hot oven burners and sat them directly on these on the countertop.
