ABSTRACT OF THE DISCLOSURE A process of providing an electrically insulative glass film on cold reduced silicon steel strip or sheet stock which will have a magnetic perme- ability greater than 1850 at 796 A/m after a final high temperature anneal which develops cube-on-edge orientation, which comprises applying an aqueous slurry containing magnesia, at least one boron compound, and up to 20% titanium oxide, based on the weight of magnesia, drying the coating, and subjecting the coated strip or sheet to said final anneal, the boron content being proportioned within the range of about 0.07% to about 0.30%, based on the weight of magnesia, in accordance with the particle size distribution and citric acid activity of the magnesia, and inversely to the bulk density of the dried coating. Improved core loss characteristics are obtained without sacrifice of perme- ability values.
