IVORYTYPE An imitation of prints upon ivory. The working directions arc as follow : Select a print upon plain salted paper, strong and brilliant ; prints from flat negatives do not give pleasing effects. Edge a glass plate with mountant to the extent of about i in. ; damp the picture, and lay it face upwards upon the glass so that it becomes fastened by the edges. The glass should be of such a size as to leave about in. margin round the print. When dry, the print will be found stretched tight upon the glass. It is then coloured with bright water-colours or aniline dyes. A flat slab of soap-stone is now taken, the glass bearing the print is mounted upon it, and the whole placed over a gas-stove or oil-stove until the glass is hot enough to melt wax. A cake of white (not paraffin) wax is then rubbed over the warm surface of the picture. The wax gradually melts and saturates
the print, which at this stage presents a hope less appearance, and appears to be ruined. The print is next cut round the edges, so as to detach it from the glass. A sheet of clean plate glass is heated in the same manner as the first piece, and the print, waxed face down, is laid upon it. The wax soon causes glass and paper to adhere, and any air-bubbles can be pressed out by using a piece of wax with a straightedge as a squeegee. The glass with the print upon it is then allowed to cool, and the print is next backed up with white cardboard, and bound at the edges with bind ing strips, or the card is attached by means of wax. Finally, the whole is framed.
Prints produced by the " Ebumeum Process " (which see) have also been called ivorytypes.
