The evolution of gases during the firing or refiring of ground coats on sheet iron or steel may be the cause of certain types of copperheading in the ground coat or in blistering of the cover enamel. The fluidity of the ground coat in the melted state on the ware has an important bearing on its ability to free itself of the gases. The calculated refractory value of an enamel is an index of its fusibility and fluidity during the firing operations. It is therefore an aid in the compounding of enamels which will minimize the defects arising from the evolution of gases during the firing of the enamels.
