I bought my first cast iron skillet and it was described as unseasoned. The brand is "Palm."
I started seasoning it following the instructions
here. I would rinse with water, dry it in the oven at 200-300F and apply 1-2 layers at a time and wait a couple days to a week in between seasoning sessions. After I reached about 5 layers I took a break from seasoning it for about two weeks. When I went to start seasoning it again recently I noticed that my paper towels would turn black when wiping. Is this normal? When I seasoned it before I didn't notice anything wiping off on the paper towels and now it seems like a dramatic difference. I'm worried that I did something wrong. I'm not sure if I should continue the process or start over. I haven't used it to cook anything yet.

I'm wondering if anyone has experience this before and if it is normal? How should I proceed? I'd really appreciate your thoughts.
