Zeolite membrane sheets for separation of mixtures containing water, alcohols, or organics are provided, as well as methods for making the same. Thin, but robust, zeolite membrane sheets having a zeolite membrane layer formed directly on a thin porous metal support sheet provide improved separations performance. The zeolite membrane layers have a thickness less than 3 .mu.m and are formed on a thin porous metal support sheet having a thickness less than or equal to approximately 200 .mu.m. The porous metal support sheet comprises an average pore size of less than 3 .mu.m, a porosity between 25% and 75%, and a thickness of less than or equal to 200 .mu.m.
