Le Creuset enamelled cast iron can be used at ANY oven temperature, with the exception of those with the black phenolic knobs, which are limited to 260C or 190C (depending on range) purely to protect the knob. "Products with integral cast iron handles or stainless steel knobs can be used at any oven temperature." "Each casserole comes with a signature stainless steel knob ergonomically designed for a much better grip and easy lifting - even when wearing bulky oven gloves. Stylish and long lasting, they add additional shine to Le Creuset Cast Iron Casseroles and are safe at any oven temperature.

le crueset say that with the enamelling process you can get bits that are missed leaving bare iron if you dishwash it then it will probably rust these will be the same probably as for the 200C comment i thought that as well but le crueset say should be used 190C max so to be expected for this sort of product
