I've scoured the other threads on the topic of seasoning cast iron but can quite find the answer to my problem. I discovered a used cast iron skillet in my grandmother's unused for 20 years kitchen. The seasoning was very warped, uneven, and flaking off in several places. So after an online search I decided to strip it and start over. (I'm foolish for not first turning to chowhound). I rested the skillet on a couple of bricks in my oven and set my oven to go through the self cleaning process. The result is what looks like a rusted skillet. At least its pinkish on the base and around the sides that true tell tale orangish sparkly rust appearance. Did I just ruin the skillet? Or are there some steps I can take to fix this?
