- 4.3 inch mini sauce pan made from 100% pure iron ore, combining traditional craftsmanship with modern DISA casting technology. After high temperature melting, molten iron is poured into a sand mould. Each pan is unique; the inner and outer walls are not polished, and minor air bubbles or flat pits on the surface are normal. - No chemical coating. The surface uses a vegetable oil carbonation process to prevent rust at the factory. For first use, season the pan: wash with detergent, dry, heat on stove with water for 2 minutes, pour out the water, dry again, then apply oil and spread evenly over the entire surface. - After use, avoid chemical cleaners before a nonstick layer develops. Rinse, wipe dry, and apply a light, even coating of oil. If rust appears, repeat the pre use seasoning steps. With time and use, the pan becomes shinier and smoother and the nonstick effect improves. Early on, some black flakes may fall off from the carbonized oil layer. - The surface has natural fine particles that reduce food contact with the bottom, creating a physical nonstick effect. The thickened bottom provides good heat conduction and heat storage, promoting fast heating, less oily smoke, uniform heat, and energy efficiency. - Specs: size 4.3 x 11 x 2.4 inches; weight 600 g; capacity 241.0 g. - Use scenarios: ideal for single servings of sauces or reheating small portions on a stove; suitable for frying eggs or sautéing small vegetables in a compact pan; convenient for camping, dorm rooms, or travel where space is limited.
