It was completely rusted. that pitting is from rust. you can see where i scrubbed each spot. i should have mentioned this is the second time thru lye and vinegar. that picture is from the first time. it looks the same. the second time
Also i dont think its fire damage as the iron was a normal color

Reminds me of the exhaust pipes on a Harley. I think heat had something to do with the rainbow.

Yes! thats exactly what it looks like. I wonder if this is a plated piece. The iron was very silvery looking. im going to toss it back in the lye
It looks like you scrubbed the pitted areas so much that you removed the thin layer of magnetite that gives bare CI cookware it's grey color. Bare cast iron, when sanded or polished, is as shiny as stainless steel. It will darken with use, but it will take a bit longer than you're used to.
I had a pan similar to that one. Pitted but no bowing, and no wobbles or cracks. After sitting in the e-tank a couple days I seasoned it and made it my daily user for a month. The pits aren't pretty to look at but the seasoning is slowly filling them in and the pan is no less nonstick than any other well seasoned CI skillet.
I also have a piece that was far more pitted than that one. Since all that pitting made the pan worthless I wet sanded it with a 60 grit disc attached to my drill. It was messy and took a couple of hours. The pan is still not collectible due to the obvious sanding job done on it but it is very smooth. The first coat of seasoning looked like there wasn't even any seasoning on the cooking surface at all. The metal was still very shiny. Second coat looked a little more glossy, but still very shiny. Nevertheless, it became nonstick fairly quickly and got darker over (lots of) time.

Turns out it was either the cheap stainless brush I was using or I was bearing down to hard on it. I am 250lb and I can really get on it.
3 others came out with bluing that i did not notice until i took pics. they went back in lye for a few hours got rinsed in water and went into vinegar. when they came out there was no more bluing

I have seasoned them and they still show a tinge of blue. All 3 pieces. Its about 20% of what it was. ill strip them again tomorrow and leave them in vinegar longer this time
