Sinterable vitreous composition belonging to the SiO2 Al2O3-Li2O system, in which the components are preselected in defined percentage fields, with the addition of elements exerting a given nucleating action promoting the growth of polycrystalline phases, intended for use as coating composition to be deposited directly in dry granulated form onto the incandescent support to sinter at high crystallization rate. |
