When placing the enamel container over a fire or in an oven to reheat food, can the lid also be kept on?

While the body is heat-resistant enamel, the accompanying lid is EVA resin that only withstands up to 70℃^[1][2]. Generally, enamel is a material made by applying glass glaze to a metal surface and baking it at high temperatures, so it withstands the strong heat of a fire or oven without difficulty. On the other hand, EVA resin, which helps create a flexible seal, can easily expand or warp when exposed to heat.

For NODA HORO storage containers, whether to separate the lid must be determined by 2 different ways depending on use. Thanks to the lid withstanding down to -30℃, food can be kept with the lid closed when storing it in the refrigerator or freezing it in the freezer^[3][4]. However, when placing the container directly over a fire or putting it in an oven to cook, the lid must be removed. To prevent deformation, high-temperature drying in a dishwasher or boiling water sterilization should also be done only with the body, leaving the resin lid out.
