This is a Staub Picot Cocotte Round 20cm Dutch oven in mustard. I purchased it and used it a few times for cooking on a wood stove, but I am selling it because I no longer use it after moving. There are white stains on the bottom of the pot, which were created during cooking. They are caused by the adhesion and sedimentation of trace amounts of magnesium, calcium, and minerals. Most of these are components found in tap water, seasonings, and ingredients such as vegetables, so they are not harmful to the body. Compatible with gas, induction, and oven. Material: Cast iron (enamel processing) Size: 20cm, top width 26cm (including handles), bottom width 17.5cm Height: 14.5cm, Weight: 3.6kg, Capacity: 2.2L Care instructions: After washing with hot water, dry over low heat, apply vegetable oil to the inside of the pot, and heat again over low heat to season the pot.
