It features four holes of about 5 mm each on the top to encourage circulation. This results in a higher amount of iron dissolving. Compared to items without holes, the iron leaching amount increases by about 30-40%. Compared to solid iron without holes, the leaching amount doubles. High-temperature tempering type is unique to Iron Maru. This high-temperature tempered type significantly increases the iron leaching amount by up to 10 times, while also slowing down rust progression. Each Iron Maru is polished by hand, making it an excellent companion for iron supplementation. For heatstroke prevention, while "hydration" and "salt" are commonly thought of, "iron" is equally important, though not widely recognized. A deficiency in iron can prevent hemoglobin production, affecting oxygen transport throughout the body. When trying to supplement iron from food, it is often in the form of ferric iron, which is harder for the body to absorb. In contrast, the iron leached from Sky Iron Maru (ferrous iron) is efficiently absorbed by the body, making it very effective. Usage is simple. Just add an appropriate amount of water to a pot or kettle and place the Sky Iron Maru inside. It works effectively in miso soup, tea, stir-frying, and even in pickling. Adding it to a rice cooker results in fluffy rice while also supplementing iron. Usage methods: - When boiling water (tea, pot, miso soup, rice). - Using it in eggplant dishes prevents discoloration. - Adding it while boiling black beans results in a beautiful black color. - For purging sand from clams and shellfish. Usage instructions: - Fill cooking utensils with an appropriate amount of water, bring to a boil, and then add the Sky Iron Maru for a while. - After cooking, remove it promptly and rinse with water. -
