An engraved wooden block is then placed upon the surface of the frame, and subjected to a strong pressure. The imprint on matrix in cameo, having been coated with graphite, is then placed vertically in a galvanoplastic bath, and a cast, an exact reproduction of the wood-engraving, is obtained. The shell is then backed with type metal and finished in the usual way. Printer and Stationer.
It has hit me in my heart of hearts, and I have shed a manly tear over it. My portrait I shall send you through H.; the medallion I must order from Paris, as there are only galvanoplastic copies in Germany. The Princess has written a few words to you after the performance of "Lohengrin," which I enclose. Farewell, and live as tranquilly as possible, my glorious friend.
The galvanoplastic process of M. Coblence for obtaining electrotypes of wood-engravings is as follows: A frame is laid upon a marble block, and then covered with a solution of wax, colophane, and turpentine. This mixture on the frame, after cooling, becomes hard, and presents a smooth, even surface.
This accumulator is of the Plante type, and is modified so as to obtain a more rapid formation, a larger surface, and a symmetrical distance of the plates from each other. The liquid of the bath supplies material for both deposits, while in galvanoplastic operations the anode supplies it to the cathode.
