COLOURING THE EDGES.

1878, by Mr. Woolnough, a practical marbler, the whole process of marbling was explained. Mr. Woolnough has since published an enlarged treatise on marbling,[1] and one that should command the attention of the trade. A copy of the Society's journal can be had, describing the process, No. 1,314, vol. XXVI., and will be of great service to any reader, but his work is more exhaustive.


Leo's Mechanical Marblers.
A transfer marble paper may now be had, and from examples sent me the process seems fairly workable. The following is the method of working sent by the importers of the paper:—

"Place the book in the press. The book edge which is to be marbled has to be rubbed with pure spirits of wine; the dry strip of transfer marble is then to be put on the edge. The white back or reverse side, whilst being pressed hard against the book edge, is to be moistened carefully with boiling water, by dabbing

a saturated sponge on it; this dabbing process to be continued so long till the colour will show through the white back — a proof that it is loosened from the paper. Then remove the white paper, and let the edge dry slowly. When quite dry burnish."

Another invention is to marble the edges by means of one or more rollers. The top roller or rollers holds the colour, which is distributed on the under rollers; these, in turn, ink the edge on being passed over it. The books are naturally held in the press whilst this is being done.
