Disclosed is a carbonate bath and an inorganic salt bath, in which a dissolved solution is a reducing bath. A bath containing a carbonate-based material contains magnesium hydride. Further, the bath containing the inorganic salt substance contains magnesium hydride. The carbonate-based material can be produced, for example, by mixing sodium bicarbonate, citric acid and a salt. Inorganic salt-based substances mainly include one or more of chloride, sulfate, nitrate, sulfide, hydroxide, borax, boric acid, calcium oxide, potassium bromide, alum, metasilicic acid, and anhydrous silicic acid.
