The properties of the earthenware surface are determined & # 8211; acidity and aluminosilicate modulus and explained their change depending on the chemical composition with a change in the content of mullite Al 2 Si 2 O 5 , quartz and cristobalite (crystalline modification of quartz SiO 2 ). In accordance with the structure of the surface, the presence of a negative surface charge was determined. It was found that silanol groups on the surface of Si & # 8211; OH earthenware, which have weakly acidic properties, provide physicochemical interaction with polymer film-forming materials with basic properties. The sorption of urea-formaldehyde oligomers of various compositions on faience and subsequent film formation in the presence of polyvinyl alcohol is considered.
