Method for annealing silicon steel strip which has been coated with a slurry of such metal-hydroxides as are capable of forming a glassy film on the surface of said silicon steel strip, which has been wound into a coil, and which has been annealed in the desired atmosphere, thereby contracting the volume of the so applied metal-hydroxides, so as to produce a space between coil-layers.
