Default #8 lid weird coating

I recently picked up an unmarked 5qt dutch oven with a weird coating on the inside of the lid. It's impervious to heat (Weber gas grill cranked on high, 2 hours at 900+ degrees on an IR thermometer). 48 hours in an electro tank does nothing. 2 days in a lye bath (easy-off method) didn't even make the rag turn black. Wire brush on a 10000 rpm angle grinder seemed to wear the brush down but did nothing to the coating. 100 grit silicon carbide sandpaper just makes the finish dull. Cracks in the middle were there when I got it, so I want the stuff off since I have no idea what it might do if it leaches into food. I've never seen an enameled lid with a coating that wasn't glossy or with a coating on the inside but not the outside which makes me think the coating wasn't a factory job. Any idea what this stuff is?

Kryptonite? Sandblasting should be given a try. Nothing to lose.

I have the same Griswold lid only mine is marked. It is an enamel finish that is the same color as the iron. Only the inside of the lid is enameled. You are wasting your time trying to remove it. It was marketed as a "clean easy" lid.

Looks like all I need to do is season it and forget it. Thanks for the info.

Gotta get the bare metal up on top to look like the rest of the dutch oven though.

I know that this is an old topic, but I was trying to find an answer. My lid coating is severely pitted. I would love to remove the coating and see the condition of the metal underneath. If its not too bad, I will season the lid and start using it.

Has anyone come across a method for removing this coating yet?

The only enamel I have ever seen removed was on an old cast iron bathtub. Only a section was removed due to cracking and some rust that got underneath.

They took what looked like a dull chisel, pretty much rounded off with no edge at all, and started tapping at the broken edge of the enamel. When they reached a point where it wouldn't chip off easily anymore, they stopped. They then sandblasted the exposed cast iron, acid etched the entire enameled surface, used a body filler type substance to fill in the scratches and chipped off area, and then sprayed on a new coating over the whole tub.

I am not sure you will be able to cleanly remove all the enamel.

Seems as though it would have been easier, and WAYYYY cheaper to buy a new tub.
