This paper analyse the wear resistance of high reflective metal oxide films of TiO_2 (anatase), Fe_2O_3 (hematite), ZrO_2 (Zirconia) and SnO_2 (Casiterite) deposited by screen printing over a conventional ceramic glaze (molar composition 0,2CaO.0,15ZnO.0,05K_2O.0,1Al_2O_3 0,45SiO_2.0,05ZrO_2). All oxide coatings increase the gloss of the substrate producing a lustre effect. Anatase films stand out for their high gloss valour and low roughness R_a. Likewise, all lustres improve the wear resistance of the glaze substrate. Hematite and casiterite coatings stand out for their relatively high wear resistance maintaining relatively high reflectivity.
