Boron oxide is also called "boric anhydride". The chemical formula B2O3 is dissolved in hot water and only slightly dissolved in cold water. Form boric acid in water. Form volatile metaborate in hot water vapor. In the molten state, a variety of metal oxides can be dissolved to obtain colored boron glass. Alkali metals, magnesium and aluminum can reduce it to boron.
