I accidently turned on the wrong burner this week and my 1-month old Le Creuset casserole was the victim of high heat for about 15 minutes. There was nothing in the pot & now there is a medium gray discoloration on the bottom of the pot the size of the small buner (about 5 inches). I wiped it with a rag & a very thin brownish residue came up, but the discoloration appears to now be baked in.
Does anyone know if this discoloration will affect the cooking qualities or the enamel? Can this be cleaned in any way? Will Le Creuset cover this under their warranty? Thanks in advance for any guidance
