Thank you for viewing. This is an authentic copper saute pan (sautoir) made in Villedieu, France, a town famous for its copperware. It has excellent heat conductivity due to the classic combination of copper and tin, and is a cooking utensil that has been used for many years in professional settings. Product Features and Appeal 【Professional-Grade Thickness and Heat Retention】 With a diameter of 18cm and a weight of approximately 1.1kg, it is made of thick copper plate. This provides high heat retention, improving the finish of delicate sauces and sauteed dishes. 【Classic Tin-Lined Specification】 The inside is lined with tin, which has excellent thermal conductivity. Tin is a material favored by professionals, but this product shows wear and tear of the plating due to use. 【Versatility of the Sautoir Shape】 The wide bottom and raised sides are suitable for a wide range of cooking methods, including sauteing, reducing, and searing. Size Details Diameter (outer): Approximately 18 cm Depth: Approximately 5.5 cm Weight: Approximately 1.1 kg Engraving: VILLEDIEU FRANCE Condition and Notes (Important) Frequency of use: Used for a long time. Inside (tin): There are areas where the tin plating on the inside has peeled off due to years of use. There are parts where the tin has completely peeled off, exposing the copper. Please check the photos. Cooking acidic foods with the copper exposed may cause the copper to leach out, so please consider re-tinning (re-plating) after purchase. Outside (copper part): There are many copper-specific discolorations (dullness) and scratches from use. Handle: The iron handle shows discoloration, rust, and uneven color due to use. **Not compatible with IH (induction cookers).** Be sure to use it with a gas stove.
