Abstract: A process is disclosed for obtaining wax honeycombs using a rigid walled mold made from walls of an elastic material which dilates under heat and contracts when cooled, the mold having at least one wall with a multiplicity of internal, parallelepiped, elastic finger shapes projections of hexagonal section extending partially through the mold. Molten wax is poured into the mold with dilation of the elastic material, and the wax is allowed to cool and solidify with contraction of the elastic material. Finally, the walls are removed from the solidified wax which is in the form of a honeycomb having a multiplicity of hexagonal cells corresponding to the projections, in at least one face.
