I have had a 10.25 inch Le Creuset skillet for a few years now. I love it a lot. It's enameled on the outside and black on the inside and I've always just assumed (like an idiot) that the interior was raw cast iron. Everything supported this conclusion. It worked like cast iron. It built up seasoning. I've seen it rust when I left water standing in it when I first got it.
So last week I realized the pan had a lot of crap burnt into it. It was not smooth and there was a thick layer of black scaly material that would not come off no matter what (soft abrasives, wood/plastic scrapers etc). So I figured what the hell, cast iron, I'll reset it.
I proceeded to use 100 - 150 and 200 grit sandpaper to take the surface off the interior of the pan. I got down to what looks like mostly raw cast iron. I polished it beautifully smooth and then seasoned it as I would a regular cast iron pan. It seems to work fine however...
...then I started reading about "satin black enamel" and I'm afraid I just sanded all the glass free from my pan. I'm afraid to cook in it. I'm afraid I've fractured the essentially glass coating on this (unusual?) pan and now using it could leach shards of glass into my food. I don't even know what I actually did. Has Le Creuset EVER made pans with raw cast iron interiors?
I know Le Creuset has a lifetime warranty and I have a few other pieces of theirs that I love/use all the time and am thankfully not too dumb to use (so far). But I need my pan and I love it too and I'm heartbroken imagining that I ruined it.
