It seems that this item (maybe all cast iron items?) is pre seasoned. Is this a kashrus problem? Any solution?
Thanks.

For most pre seasoned cast iron, put it through a self clean cycle in your oven to remove the seasoning, then toivel, dry immediately and thoroughly to avoid rust, and re season.

For this item I'm not sure the handle would tolerate a self clean cycle (really want to say I'm not sure the handle would handle it)
Don't ask stupid questions and you won't get stupid answers

If produced in the USA, the seasoning is almost for sure vegetable oil. Vegetable oil does need a hechsher because of keilim issues, but it's extremely unlikely the cast iron piece became treif from treif fats directly. I know some rabbonim who say it doesn't need any kashering.


COR holds they do not need kashering, mostly because the seasoning process in the factory includes heating the oiled pan at temps of ~500 degrees for an hour. thats sufficent for libun kal, so the pot is already kashered. the black residue is not food, and can be considered as burnt and destroyed
https://cor.ca/view/873/cast_iron_cookware_preseasoned.html

CRC says hagalah
https://www.crcweb.org/Sappirim/Sappirim%2022%20(Jan%202012).pdf

the ou says libun (gamur?)
https://oukosher.org/halacha-yomis/i-bought-a-brand-new-pre-seasoned-cast-iron-skillet-must-this-pan-be-kashered-before-it-may-be-used/?category
they argue that the black layer needs to be removed. and the simplest way to do that is to leave it in the oven on a self clean cycle.

they don't deal with the libun/hagalah question, but i'd assume that if you sanded it down fully, they'd agree that hagala/libun kal is enough.

The ok holds libun kal, based on the psak of R Weissmandel a"h

Doesn't seem to be certified. If you get an authorized letter from the company there is makom lhakel according to Rav Moshe. AYLOR

Right, but if one is willing to rely on RSM that they are all ok as is, it would seem that this is the best one to get, no?

Curious why removing seasoning is not breaking the kli? It’s really unusable in this state as it will rust, maybe no tvilah, probably no Bracha, and maybe you have to wait until after seasoning?

It needs to be broken to the point that it needs a maaseh uman. Is seasoning a maaseh uman?
I wonder what people who type "u" instead of "you" do with all their free time.

Probably. Just because you can learn from google doesn’t mean it’s not skill. Most car trouble can be done that way- so is it ok on chol hamoed🤔

IMO, anything one can learn from a cursory Google search is not a maaseh uman. A maaseh uman is something that requires umnus, i.e., expertise/craftsmanship/professionalism/experience...
It's like comparing following a recipe in a cookbook to making a dish that only chefs can pull off.
Same re car repair: depends if it is simply following instructions or needs actual expertise.

The kli isn't broken by taking off the seasoning. It can be used for many things until it rusts (and rust can be removed presumably).

most people assume replacing a battery or doing an oil change is umnos although the previous generation did it themselves.
I’ve seen many mechanics don’t know what to do when replacing certain parts without looking it up

If you can’t use it for its intended purpose, then it’s not the kli That you had in the beginning, so you really broke it by removing the seasoning. So what if I can use it to store screws in?

it is very much halachikly still a kli for tumah/tahara purposes which is what counts.

What is the source for that? I assume that if you have a hot water urn which can still function to hold water if you remove the heating element and replace it you would not have to toivel , Please correct me if I’m wrong

Iirc this is discussed in poskim, a kli that can no longer hold nuts let's say because it has big holes but it can now hold bigger fruit
