A method of manufacturing a sponge support made of a metal selected from nickel, copper and lead, including (a) impregnating a sponge made of an organic material based on polyurethane, polyester or polyether with a solution of a nitrite or a sulfate of the metal, the concentration of the solution being a function of the desired weight per unit area for the sponge made of metal, the sponge made of an organic material has a porosity in the range of from 96% to 98% and a pore-size in the range of from 200 (my)m to 400 (my)m, and (b) heat-treating the impregnated sponge to remove the organic material.
