Компоненты стекловидного покрытия сплавляют при 1200°С, расплавляют, гранулируют в воду. Полученную фритту смешивают с 0,2% электролита, 48% воды и размалывают до остатка не более 0,2% на сетке №005. Суспензию наносят на поверхность изделий и выдерживают при 800°С.The components of the glassy coating are fused at 1200 ° C, melted, granulated into water. The resulting frit is mixed with 0.2% electrolyte, 48% water and milled to a residue of not more than 0.2% on mesh No. 005. The suspension is applied to the surface of the products and kept at 800 ° C.
