PURPOSE:To prevent iron from oxidizing, corroding, and deforming by using calcined calcium obtained from the crustacean, fishes and sellfishes, etc. CONSTITUTION:The calcined calcium is manufactured by thermally calcining calcium parts of the crustacean, fishes and sellfises, etc., at about 600-200 deg.C. The calcined calcium, its dissolved liquid, and its electrolyte liquid are used for iron, iron-dissolution liquid and iron electrolytic liquid. Consequently iron, the iron-dissolution liquid, the iron electrolytic liquid, etc., are be prevented from oxidizing, corroding, and deforming.
