Hey all, new user here, so I apologize if this has been done too much before.
I've got this old pan that I think (based on some quick internet research) is cast iron, possibly enameled at one point--see the shiny bits in the second pic. The bottom says "Chef Skillet - 9 inch - Made in USA - %" with an X at the base of the handle.
Following another site's instructions, I soaked it in vinegar and water for about 1/2 an hour before realizing the shiny stuff is not coming off (though it did remove a lot of rust).
So, does anyone recognize it? Any help much appreciated. :)
