An investigation was made of the gases evolved during the firing of vitreous coatings. The is shown that the principal gases evolved during the firing were carbon monoxide, carbon dioxide, and hydrogen. The blistering that is often observed in the early stage of firing when vitreous coatings are applied to low-carbon steel was found to be caused by evolution of the carbon gases formed by the oxidation of the carbon in the steel.
