Abstract
Abstract A method of producing vitreous layers on any type of substrate material in which an alkali-containing multi-component glass having at the most 10 percent by weight of alkali oxide is heated in an electron beam furnace to a glowing condition and then is subjected to the action of the electron beam which vaporizes the pre-heated glass and deposits it on the substrate material.
