A tray or basin for ablutions is a vessel used to hold water for ablutions during pontifical masses and by celebrating priests during various liturgical ceremonies (ashes palms washing of the feet on Holy Thursday baptism). The basin for ablutions is always accompanied by a ewer.
Since no written proof exists (receipt or inventory) the nearly immemorial use of these two pieces together in the archbishopric oratory leads us to believe that this ewer and this tray were a pair.
