Several years ago, I bought a 5 qt. DO at an HEB supermarket here in Texas. The cookware is sold under the Concinaware branding (which might be branding for the store; I don't know for sure.) Anyway, after years of use and a lot of cleaning of the the bottom, the enameling is flaking off. I won't use it in that condition lest we ingest enamel flakes, but I was wondering if I could use it as a cast iron DO if I blast off the remaining enamel inside. The outer enamel coating is in great shape. My concern is that there might be some noxious element used in the process of enameling CI that could remain in the CI pores after removing the enamel.
Does anyone have any experience with this? I'd appreciate your thoughts and comments.
