| Abstract: | Variations were made from 5 to 25 % in soda oxide and boric oxide content of a given ground coat enamel, and results observed on trial pieces. It was found that an increase of soda oxide at the expense of boric oxide decreased the tendency of the enamels to blister and fishscale, and increased the tendency toward the formation of copperheads. Conversely, the increase of boric oxide at the expense of soda oxide increased the tendency of the enamels to blister and fishscale, but decreased the tendency to copperhead. |
