No. 21 Nonpareil or Comb
We now come to this well-known and very popular pattern, which has had a most extraordinary run, and which some people hardly seem tired of, although it has become so common of late as to be used on almost every kind of work.
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.
