  • Patent number: 4993472
    Abstract: A novel sprue is used to cut wax and obtain the impressions of finger or other digit prints in a quick and effective manner. The sprue has an elongated handle connected to an impression plate having walls on its perimeter which cut easily through thin layers of wax when downward pressure is applied on the bottom of the impression plate. Then the wax is heated by a heat lamp until the top surface is melted at which time a finger or digit is placed on the wax and with downward pressure applied until an impression of the fingerprint or other digit print is left in the wax. After the wax is cooled then the impression can be imparted in gold or other metal jewelry by standard jewelry casting techniques. The result of this method is a memento that can be attached and worn as a necklace, bracelet, ring or other item of jewelry.
