Lodge actually directs consumers to season the cast iron by applying oil/ shortening and putting it at 350-400F for one hour. That is below the level of kash nisraf. Perhaps their preseasoning is done at similar temps.

You don't think straw would burn after an hour at 350?

I think the thread needs to be split from here.

CMIIW but I think it's whether straw will burn on contact with the thing that was at 350 for an hour. And it probably wouldn't.
If you don't care why would you comment?

Rav Belsky ZTL told me in the name of R" Yaakov ZTL otherwise.

Do you have to kasher a Lodge cast iron?
my uncle called OU (iirc) they said stick in the oven on self clean for at least 4 hours it should totally discolor and burn all the seasoning.

Why do I have a feeling that this thread is going to end up as an infinite loop?
I've been waiting over 5 years with bated breath for someone to say that!

What is the level that Rav Belsky writes? Paper will spontaneously combust at around 450 so it would probably burn at a lower temperature than that.

That Lower temperatures with longer times is ok .
It’s a huge chiddush , not the pashtus .

I don't see at as the major chiddush that you do. It is clear in the rishonim that the burning straw is NOT a level of heat but rather a way to be certain that the kli is heated all the way through. More time at lower temperatures will also accomplish that.

מרדכי סוף מס' ע''ז
אבל אותם הבלועות התיר ...אז אין צריכין ליבון גדול דנשירת קליפה אלא רק עד שתהא יד סולדת משני עבריה וגם רגילים לבדוק ע''י נתינת קש מבחוץ לראות אם הקש נשרף בהכי סגי דא''כ שליט הליבון מעבר לעבר אע''ג שלא תשיר קליפתו ומ''מ די בכך דכיון
 דהתירא בלע א''כ די להם בהגעלה ואע''ג דתשמישה ע''י האור כדמשמע בשמעתא והא לא גרע אותו ליבון מהגעלה ואותו ליבון מפליט יותר מהגעלה
This is what's brought down in the ב''י  as well. It seems clear from the Mordechai that יד סולדת משני עבריה & הקש נשרף worked about the same. (It seems clear that the Rem"a didn't agree with  יד סולדת משני עבריה but the Shulchan Aruch Harav did. The PM"G makes a 3rd level) but from the Mordechai it should be clear that kash nisraf can happen at below 440F

This article seems to be more about haystacks than about individual pieces of hay and more due to combustible gas from chemical reactions in the hay than the hay itself.
Quote
When the internal temperature of hay rises above 130 degrees Fahrenheit (55 degrees C), a chemical reaction begins to produce flammable gas that can ignite if the temperature goes high enough.

Fine, so what is the temp at which dry hay spontaneously combusts? We know that paper is at Farenheit 451, or at least we think so because of the book.

They say they are using soybean oil, whose smoke point is around 350, so it's possible they are seasoning at 350, but I would bet they are doing a lot higher.

very difficult to understand. Cast iron is one of the easiest metals to do a libun gamur on since it can withstand very high temps. I've kashered cast iron with libun gamur many times without any issues.
