Zusammenfassung:	PURPOSE:To form a glass film having superior adhesion and fine appearance by applying a protective coating material for annealing on a steel sheet and drying it while regulating the average amount of water evaporated from the slurry. CONSTITUTION:An MgO-base protective coating material for annealing is applied on a steel sheet cold rolled to the final thickness and subjected to decarburization annealing, the coating material is dried by heating and the steel sheet is subjected to finish annealing. At this time, the average amount of water evaporated from the slurry in the drying stage is regulated to
