So much good information in a short video. Thanks!

[@PrudentReviews]

Glad it was helpful!

A very scientific subject explained and demonstrated so anyone can grasp the science. Well done. Thx for doing this, filming it and sharing it with us. 👍👍👍👍👍

[@PrudentReviews]

I'm glad you found it helpful! Thank you for watching and supporting us.

Glad you mentioned thickness of the pans. One hotel where I worked would buy the cheapest aluminum pans and it was like cooking on aluminum foil. Other places had thick gage aluminum pans and I never seen them warp. My preference is thick stainless steel for bakeware. No warping and very sturdy. If my kids can't destroy it, then it's outstanding. I like how my cakes come out evenly when baked in thick pans. As for stove top cookware, I've only seen cheap crap warp. My first pots and pans come to mind. Never have had any warping happen with my heavy disc bottom pots and pans. 30+ years and my kids haven't destroyed it.

Too rapid heating of frying pans (skillets) on Induction Hobs is a very common cause of warping. People can also damage Enamelled Cast Iron cookware (e.g. Dutch Ovens) on Induction Hobs if the initial heating is too rapid. On an Induction Hob it is best practice to begin with a low power setting for the first couple of minutes, after which you can increase the temperature up to what's needed for your cooking (which is typically a far lower temperature than most amateur cooks believe). It is rare that you ever need to cook anything on high heat; low to medium is typically all that's needed.

I cook on high on an induction. If you're searing a lot of meat, then you need that power.

Very helpful, well-presented information. Good job!

[@PrudentReviews]

Thank you

I learn so much from this channel!! Thank you for sharing all of this wisdom. I'm embarrassed to say, I'm 65 and never knew. I don't even think my mother knew. Great channel!

[@PrudentReviews]

I’m glad you found it helpful! 😊

Great video with lots of useful info. Thank you.

[@PrudentReviews]

Thanks for watching!

[@stevenwilgus8982]

I can't believe the density of things I did not know or consider. Holy cow.....this was AMAZING.

[@okidave]

I have a nice carbon steel frying pan I was about to throw away because of concave warping in the interior of the pan. I will definitely try what you demonstrated to get it flat again.

[@staceymalave4991]

Great explanation & demonstrations! 👏 thanks so much for all the precise details! I'm going to get my pan wood & hammer now 😊

[@PrudentReviews]

Let me know how it goes! :)

[@johnreseigh4868]

I have used a wooden mallet to flatten the bottom of the pan. It works well and doesn’t dent the pan.

[@megalattie3824]

Beautifully explained, and very very useful video.. I gave you a "Like"..

[@Finkeldinken]

Ooh, I am going to fix my old crèpe pan that I gave thermal chock by accident many years ago. Thank you!

[@PrudentReviews]

Let me know how it goes!

My 8" All-Clad D3 skillet warped on my induction range after a few days. I always heat it slowly. I did rinse it with hot water when it was semi-cooled down. I thought the temp difference wouldn't be too great. But it did warp slightly after. So be very careful. And be patient when waiting for the pan to cool. Let it fully cool before trying to clean it.

[@JohnnyQuaykersBelmont]

Thank you!

[@Subgunman]

One reason why I like high carbon steel skillets. Aluminum warps too easy plus when used at high heat it releases unwanted chemicals especially those with non stick coatings.

[@taliaperkins1389]

That fixing is only for aluminum pans, right? Steel would need far higher temperatures and like a welding blanket.

[@PrudentReviews]

It will work on most steel pans too. Steel pots and pans are made primarily of aluminum with a very thin steel interior and exterior.

[@Gyro_Pretzeli]

@@PrudentReviews Butc ast iron not, I assume?

[@AriaOnEdge]

The whole towel and mallet thing didn't help at ALL, but when you did the just brute forcing it trying to bend backwards, While i'm assuming it's going to warp again, it's almost back to nearly flat. It's amazing!

[@AriaOnEdge]

I'M BACK. after man handling the pan and straighting it out, I've been careful to not cool the baking sheet before AND after using it it in the oven and it's STILL STRAIGHT!!! and I used it twice now! #1 way to fix a warp is to be careful not to warp it in the first place. #2 might be just bending it back! I"m still amazed, the simplicity and effectiveness of this is 100% real!

[@stevenwilgus8982]

The best practice process is to "always" change heat slowly and "gently". The few times it is done fast is when one is quenching a sword or tool to temper it: otherwise, it's more than best to make temperature changes slowly. This applies to Pyrex, and Corelle ware too by the way. Place warm or hot onto a DRY towel only until it cools down.

[@leedoss6905]

A couple of good wacks in the middle with a brass mallet works wonders. No need for all the elaborate cushions.

[@alonsoperez3637]

What might happen if you fix a warped pan many times after it gets warped again?

[@peaceful3250]

I always put heated water in a hot pan rather than waiting.

[@leannevandekew1996]

Ceramic and Glass ware prevents all these problems. Corningware and Pyrex are excellent.

[@PrudentReviews]

Yes that’s true. But those materials have other limitations.

[@WindLake]

@@PrudentReviews I've heard that Pyrex is good only if the name is in all caps (PYREX), because they sold the rights to their name in lower-case (pyrex) to a manufacturer that produces cheap products prone to shattering. True or not? BTW, this warping video was excellent.

[@PrudentReviews]

@@WindLake I haven't heard that but will look into it. Appreciate the tip! And thanks for watching - glad you found it helpful.

[@theheartoftexas]

@@WindLakeYes, that’s true. PYREX is made from borosilicate glass. This is what glass top stoves and refrigerator shelves are made from. This is the glass that is capable of better withstanding thermal shock. PYREX used to advertise that their dishes could go from the freezer to the oven. That’s because it was made of borosilicate glass. pyrex is made of soda-lime glass. It’s cheap and doesn’t withstand temperature variations well at all. You can easily tell the difference between the two glasses when you are looking at clear glass pieces. The borosilicate glass is clear and white. The soda-lime has a green caste to it. However, there is clear white glass that is very cheap and breaks easily, this is usually used to make cheap glassware. I’m referring to baking dishes. With the opaque, white dishes, or colored dishes, you have to go by the logos. This is why you hear so many complaints about the new pyrex. You hear about people taking a casserole out of the oven, only to have the dish shatter immediately. This is because the soda-lime glass can’t tolerate the thermal shock caused by the change of temperature between the oven and the air temperature outside of the oven. Hope this helps.

[@WindLake]

@@theheartoftexas Thanks for such thorough info.

[@musicalsaber6433]

To the ice in hot water example, water is actually one of the few materials that expands when it freezes, and contracts when it melts, to be a total nerd 🤓

[@nidjeveze4616]

All clad pans for flat stove not good. Best for gas stove.

[@PrudentReviews]

I’ve found they work great on both. Have you noticed issues on flat cooktops?

[@davidcarr7436]

And by my own experience, DO NOT BUY anything from an infomercial!

"Chekov, warp back to 2".
