Marbling of Gilt Edges
If gilt, silver or aluminium edges are to be marbled, burnish slightly and moisten by a soft brush with a solution of powdered alum in hot water which is of the consistency of a thin pap.
The marbling of the gilt-edge is then executed in the usual way before the coating of alum is entirely dry.
After the marbling is done, water is poured over the edge until it is entirely clean.
When the edge is completely dried it is rubbed over with a waxed rag and is then burnished in the usual way. For marbling the usual marbling colors are applicable, but it should here be added, that very dry edges will not take the marbling colors readily.
