FACTORS GOVERNING ADHERENCE OF ENAMELS APPLIED TO SHEET IRON

A series of tests were conducted to ascertain the effect of nickel deposition and firing variations upon the adherence of enamels applied to special enameling sheets. Limits were established for securing optimum adherence of zirconium-opacifid white, antimony-molybdenum-opacified white, and commercial blue ground-coat enamels.
