Petromax cast iron pan, with handles. Cast iron, which optimally transfers and stores heat, before use is recommended to be cleaned with hot water, then it can be used immediately. The first few times you use the pan, do not cook any acidic food, because it can damage the protective coating of the fire pan. Suitable for outdoor cooking on an open fire in an oven, over a campfire or on a suitable grill or stove at home. Caution: Protect your hands with heat-resistant gloves or a napkin when touching the hot pan. Recommendations: • Do not pour cold liquids (such as water) on the cast iron parts of the hot pan, because the cast iron may crack or otherwise be damaged. • Do not allow the fire pan to fall on a hard surface, because cast iron is a brittle material that can crack.
