The top colours alluded to in both Marbling and Graniting, should be mixed in turpentine, with a little japanncr’s gold-size to bind; otherwise the colours may flake off in varnishing.
Black and Gold Marble.
The ground is black. Mix a little white, red and yellow separately, on a board, and with a camel-hair brush give first the ‘white-veins’ in thin white to break the surface, then put in the ‘insects’ (little three-cornered bits) and connect by lines of various thicknesses. With the colours on the board, blend and mix the tints to the desired effect. After this is done, mix a little black with the white to make a light lead-colour, and, using it thin, fill in the spaces, leaving a margin of black visible. When dry use a good hard coach varnish.
White-Veined Marble, suitable for a hall-porch, should have a white ground, ‘oceans, seas and rivers’ being put in while the last coat of paint is wet with a piece of charcoal or a marbling-crayon. Gently draw the edges of a soft, dry duster over the work, to blend the colours.
Ground Graniting is done off either a red or lead-coloured ground, according to whether a red or grey granite effect is required. The ‘spots’ can be made lighter or darker than the ground colour, as desired. To make these, dip a sponge in the colour to be applied, dab once on a board to remove surplus colour, then dab over the ground until evenly ‘spotted.’ Apply white first, then red, and finally lead-colour. When thoroughly dry, rub with fine glass paper, and varnish.
