Scientific paper

Mare soil and orange and black pyroclastic glass were reduced in hydrogen gas at temperatures of 900 to 1100 C. The experiments support studies of regolith maturation, lunar volcanism, and the production of oxygen on the moon. The most reactive component in the high-Ti soil was FeO in ilmenite, which was completely reduced to iron metal at all temperatures. Vitreous orange glass crystallized and was partially reduced to iron metal, pyroxene, and minor olivine. Initially devitrified black glass was similarly reduced and converted to iron metal, pyroxene, and minor olivine. The degree of reaction in both glasses increased with temperature.
