Abstract

Abstract A method of forming artificial fingernails includes the steps of forming a negative impression mold of a human finger, and then making an artificial plaster finger from that impression mold. Once the plaster finger has cured, a layer of tape which has been cut and shaped to the desired length and contour is applied to the outer end of the nail portion of that plaster finger. Thereafter, another negative impression is made and another artificial finger also of plaster is created. This second plaster finger is identical to the first with the addition of a plaster portion representing the artificial nail. This plaster finger is then coated with a lacquer to seal the plaster and a heavy layer of lacquer is placed over the nail portion after any unevenness has been smoothed out. Once the plaster finger is finished, the nail portion and surrounding top portion of the finger is covered with a layer of silicone rubber. After this layer cures, it is placed in a backing mold member which is filled with wet plaster. When the plaster sets, a silicone rubber master mold results. Artificial fingernail material is then placed in the mold and the mold is pressed onto the corresponding finger.
