Produced by printing over colored edges. It is certainly proper to endeavor to brighten colored edges by spreading on bronzed color.

That this process has fallen more or less into disuse is probably due to the tiresome labor necessary for the making of such edges. It gives us the possibility of producing manifold changes in edges because silver or gold ornaments can be put on any color as well as on the white edge.

We have here the possibility of adapting the design of the edge to that of the cover, which under other conditions can only be done with chased edges.

It is an erroneous idea to disfigure genuine gilt-edge by putting on bronze ornaments. The base and perishable bronze can never be the correct material to brighten the effect of genuine gold.

The bronzing of edges can only be applied to colored or white edges but not to genuine gilt-edges.

For the production of bronzed edges, the following articles are necessary.

First, Engraved plate or Cliche representing the ornament with which the edge is to be decorated.

Second, Thin leaves of roller composition for the transfer of the ornament from the plate on to the edge.

Third, Roller for rolling in the gravure.

Fourth, Thick, fluid, strong amber-lacquer, as binding medium between the bronze and the color of the edge.

The following rules should be observed.

The treatment of the book block is similar to that of the hollow edge, therefore the book, after the fore edge has been cut and rounded must be scraped hollow.

As colors for the edge, the above mentioned colors, carmine, cinnabar, cobalt-blue and others are recommendable.

As binding medium a strong albumen or gum-arabic should be used. Aniline colors can be used for this purpose, but they must be dissolved in alcohol.

Such edges have a bewitching appearance if they are made in the same shade of color as the cover, but they render a certain practice in the mixture of colors necessary.

The coloring and burnishing of the edges is executed in the same manner as described in the article upon the production of colored edges. After the burnishing of the edge is executed, the time has arrived to imprint the ornament upon it.

Cut off of the thin leaf of roller composition, a strip slightly larger than the surface of the edge. Put a little of the thick, fluid amber-lacquer upon the roller, and move the roller forward and back on a smooth stone (marble slab) until the lacquer is equally spread out over the surface of the roller. When this is done, the gravure can be rolled over by aid of this roller.

The thin strip of roller composition is then carefully placed on the gravure, pressed on lightly and evenly with cotton wadding or a soft rag. By this means the ornament of the gravure is transferred to the roller composition.

To transfer this ornament on to the surface of the edge, it is necessary to lay the strip of roller composition carefully on the edge and carefully and evenly press it on.

The bronze is not to be put on to the edge on which the design is printed before the lacquer is quite dry, only then can the blurring of the ornament be avoided and the bronze be made to retain its specific metallic lustre.

After the lapse of several hours, the bronze will be dry, and then the cleaning of the edge is done with soft cotton wadding.

The strips of roller composition so used must be cleaned immediately after use with clean turpentine and, after they are dried, they can be again used.

In order to produce the necessary transfer strips use only the best English roller composition. Cut this mass into small pieces, place them in an earthen vessel, subject them to a moderate heat until they become entirely fluid and pour the fluid mass on a piece of glass or a smooth sheet of tin. After this has cooled it should be carefully removed. To render this easier, the plate of glass or the piece of tin should be lubricated with some fine oil.
