    • n electrotype A copy in metal (precipitated by galvanic or electric action, usually in the form of a thin sheet) of any engraved or molded surface. Copies of medals, jewelry, and silverware, of woodcuts and pages of composed type, are common forms of electrotypes. The metal most used is copper, and the largest application of the process is to the preparation of plates for printing. The form of composed type is molded in wax, which is dusted or coated with blacklead in order to make it a conductor. The wax mold is suspended in a galvanic bath of sulphate of copper, through which a current of electricity is passed. The thin shell of copper which attaches to the mold is afterward backed with stereotype-metal. Also electrostereotype, and commonly abbreviated electro.
    • electrotype To make a plate copy or plate copies of by electrical deposition.
