Zusammenfassung:	PURPOSE:To simplify a pretreating process before enameling, to impart suitability to enameling even to an ordinary steel sheet which is difficult to enamel by the conventional method and to attain contribution to qualitative and quantitative extension of enamelware. CONSTITUTION:Oxide scale 2 on the surface of a hot rolled steel sheet 1 is removed with electric arc 3 in vacuum, the surface of the steel sheet 1 is roughened with the arc 3 and enameling is carried out. In the case of a cold rolled steel sheet, the surface of the steel sheet is roughened with electric arc in vacuum and enameling is carried out.
