This SCANPAN Coppernox 24cm dutch oven expands on traditional cookware with its unique construction. The base is impact bonded with a copper wedge for rapid and even heat distribution. To assist with heat retention and elimination of hot spots, the copper wedge is enveloped by 2 layers of aluminium with stainless steel surrounding the entire piece. This combination provides optimal heat diffusion and control. The sturdy lid with stainless steel rim and tempered glass insert allows you to view the cooking process. The range features cast stainless steel handles with soft touch and comfortable silicone inserts and a internal mirror polished 18/10 stainless steel finish with capacity markings. The range is suitable for all energy sources, including induction. Do not use harsh scourers Routine Cleaning - After cooking, do not put cold water in hot pan, wait until cool, remove all food and fat residue using hot soapy water and nylon cloth/brush Heat tint or streak marks can be caused by excessive high heat.
