Abstract
ABSTRACTSpectrographic analyses were made of the gases evolved when enameling iron, ground‐coat enamel, and iron enameled in ground coat were heated in vacuo at various temperatures. Below 1200°F the gases from enameling iron contained hydrogen, water vapor, carbon monoxide, carbon dioxide, and nitrogen. Between 1200°F and 1600°F. the gases from enameling iron contained carbon monoxide, carbon dioxide, and nitrogen. The gases from dried ground‐coat enamel slip at temperatures not exceeding 1600 F consisted principally of water vapor. The gases from ground‐coat enameled iron (reboiling gases) contained hydrogen, water vapor, carbon monoxide, carbon dioxide, and nitrogen.
