The invention relates to an electrically conducting material, in particular an electrically conducting varnish, for the preparation, preferably by electro-deposition, of dental moldings. This material comprises at least one component which brings about the electrical conductivity and one dental spacer or die spacer or the constituents of such a spacer. The material preferably comprises at least one additional component, in particular at least one colorant, which gives rise to an alteration in color or a change in color when the electrically conducting material is dried.
