Based on comments I'm not sure if this is bad or good for seasoning?

Not OP but I believe OP is showing this as a bad thing. Mom has been incorrectly cleaning the pan so the patina is all gone. The patina is part of what makes cast iron so good to cook with and takes a lot of time or some effort to build up. So itβs sort of like getting something nice and trashing it.
Ready to season. Looks great!
Talk about "burn a' the steak", this is heresy! ππ±π€πΌ
What grit did you use for this? I've always been curious about sanding down the rougher surfaces, but haven't pulled the trigger since I've read conflicting results about seasoning after the fact.
Steel wool and elbow grease is what it looks like to me.
Isnβt steel wool too fine for removing bumps?
For finishing, sure. But Iβd be looking around 600grit for my first pass.
I dunno for sure, but that looks like something in the 400 grit range followed by steel wool.
It's a lot of work tbh. Enough so that I don't do it any more.
But, it does improve the cooking surface. You sand down and season with flax oil, and you've got a great surface that even eggs won't give you too much trouble cleaning up.
It doesn't have to be perfectly smooth, mirror finish. And some small pits are okay. No need to really grind the hell out of a pan, you just want to kinda even it out so there's less texture, with the end point being where you decide is good enough.
Back the last time I did one, I used an orbital sander with 200/400/600 progression, then hand sanded to 800, and it was more than smooth enough. Going past that is diminishing returns. I've seen people do a mirror finish and it wasn't worth the time imo. Even 800 is kinda extra tbh. You just don't want highly visible scratches.
There's no reason to sand it down. It just makes the pan worse.
Nah the nice machine finished cast irons with the smoother finish are soooooo much better, take longer to get a good seasoning on them but when seasoned are fantastic
How does seasoning stick on a smooth surface?
Strictly speaking it's still porous at the microscopic level
Same as it does on a rough surface.
You get the oils polymerizing, which is going to stick to pretty much anything, no matter how smooth it looks. The surface isn't microscopically smooth, there's still roughness.
However, it wouldn't matter if it was perfectly smooth. The bonding between the iron and the oils isn't purely mechanical. It bonds on a molecular level, meaning that the little bits on the atoms of the polymerized oil make sweet, slippery love to the little bits on the atoms of the pan.
A smoother surface is actually better. You don't have as irregular a surface on the polymer, and there's less gaps where they contact the metal. Which, ideally, you'll be applying very thin coats and prevent gaps, but it's never a perfect process.
Sanding down a pan before seasoning improves the bond, improves the cooking surface, and makes it easier to season.
You ever use a stainless steel pan of some kind and have oil get solid-ish on it? It leaves that layer of brownish, maybe amber stuff that's slick and hard to scrape off. It's the same thing. You can polish stainless still to a mirror finish and that will still happen, and it'll still be difficult to remove.
When it comes to that, a rough surface is more likely to chip, flake, or otherwise fail.
Your best seasoned pan is going to be sanded smooth, then seasoned with food grade flax oil (though it is by no means the only option, it's the best drying oil that's food grade). You'll cycle it three to five times, depending on your freedom to do so. Then you'll have very low stick, heat resistant surface.
Now, nothing is perfect. If you can't get flaxseed, stuff like canola that's semi hardening will work almost as well (most of the time, you can't tell the difference until or unless you abuse the hell out of the pan). If you can't get that, any oil that's safe to eat will get the job done to some degree, so long as it's heat reactive at oven temps. Which, if you can't get flaxseed, the chances of being able to source anything that unusual isn't likely to begin with.
Same way it sticks on every carbon steel pan which are all smooth.
I'm well aware that it doesn't necessarily improve anything, which is why I've never sanded my Lodge pan down. However, I also don't see how it would make the pan worse, which is why I'm asking how it impacts the ability for seasoning to adhere, the only thing this could possibly do to make the pan worse. I use a 1950s Wagner for my cast iron cooking now, and I much prefer its polished surface to that of a stock Lodge. I've done plenty of my own Googling to find anecdotal experience with sanding down the surfaces and did not find definitive answers on sanding, so if you have any sources on it being strictly worse or personal experience I'd be happy to learn more.
Iβve been cooking with cast iron for decades, first with rough lodge pans then for the last 15 years after sanding them smooth. IMO smooth cast iron is far away the better cooking experience. Trying to get stuck bits out of the rough surface is a nightmare. With a smooth surface and a nice metal spatula (Dexter is the brand I use) nothing ever sticks and the seasoning sticks perfectly well. Iβd just recommend getting carbon steel pans to anybody that doesnβt have smooth cast iron yet, as theyβre much lighter and perfectly smooth out of the box.
Agreed. A few weeks ago I spent the time to sand smooth 3 of my lodges and they are way more nonstick after 3-4 uses than they were before and way easier to clean. I just used 80 grit on a dynafile, took about 15 minutes to sand them smooth (wear a mask). Then 2-3 runs through the oven to re season and they were good to go.
I used a random orbital sander and it took a pretty long time to get it as smooth as I wanted. Still worth it for a pan that will last forever!
This hurts. I have that same pan and I love it. Poor thing.
Nice and smooth!
Ready to wash in a dishwasher.
Why would she commit such a crime...
