For this description of marbling use the solution of gum alone in the trough. Mix the colours with gall and water, taking particular care to avoid all oil and grease of every description; but the colours will require to be thicker, and more colour thrown on, than for Spanish, with the exception of the last, which will not require to be so heavily thrown on as the last Spanish colour. Let all the colours be thrown on in about equal proportions. In commencing, proceed as usual:—first, skim the surface of the solution, and immediately follow with the red so as to well cover the whole surface of the solution; then black; next, orange or yellow; fourthly, blue; and, lastly, the top colour, of whatever shade it may be required. Now take the peg-rake, which must be as long as the trough from right to left, and which consists of a piece of wood having pegs inserted about an inch and a half apart and about three inches long, tapering towards the point, and having the appearance of the head of a rake. Pass this once up and down through the colour from front to back, taking especial care that when you draw it back the teeth come exactly between where they went up. Having raked the colour into the proper form, take the comb, which must reach the whole width of the trough from front to back, and draw it steadily through the colour, and the pattern is ready for the laying on of the paper, which must be done with a steady hand, or there will be shades in it.
No. 22.—raked nonpareil.
A very good pattern is made by following the directions for No. 21 until the colours are properly raked, then beat a little white evenly over it, and it is ready for the paper.
No. 23.—nonpareil, (reversed.)
Another pattern is made by precisely the same process as No. 21, till the colours have been raked with the peg; then take the comb, which should be a much larger one, and draw it through the colour from left to right, then immediately reverse it and draw it back again from right to left, and the desired effect will be produced.
No. 24.—antique.
The antique marble is executed thus: after the three first colours have been thrown on, namely, red, black, and yellow, rake it once up and down with the peg-rake, after which proceed to throw on the green, follow with the pink spot, and lastly, beat or knock on small white spots. Some antique patterns are made with a blue or other coloured spot, in lieu of the pink here described, but the process is the same.
No. 25.—antique, (zebra.)
This is done with colours prepared the same as for ordinary nonpareil; throw on four colours, viz.: red, black, yellow, and blue; then rake the same as for nonpareil, after which throw on a light colour for a spot; lay on the paper the same as for Spanish. Sometimes it is made without shading, and passes for another pattern.
