AbstractGround‐coat enamel was first applied on one side and then on each side of 26‐, 20‐, 18‐, 10‐, and 6‐gauge enameling stock, and the strengths of the pieces were determined in cross bending. The results show a decided increase in strength for the enameled specimens over that of the stock before enameling. An increase in the thickness of the enamel also increases the strength within limits. The effect on the lighter gauges is greater than on the heavy gauges, and the strength is greater when the enamel is under compression than un
