Having, therefore, mixed and prepared the colours,—having the preparation of gum and flea-seed in the trough,—proceed to throw on, first the red, then the blue, and lastly, with a large brush full of colour, the olive; beginning at the left-hand corner of the trough, farthest from you, and working down and up closely all over, taking care not to go twice over the same place, or you will produce rings by the falling of one spot upon another, which is considered objectionable. It cannot, however, be entirely avoided. Now take up the paper by the two opposite corners, and, holding it as nearly upright as possible, yet with a degree of ease and looseness only to be attained by practice, let the corner in the right hand gently touch the colour on the trough, while, at the same time, you shake or move it to and fro by a regular motion, at the same time, with the left hand, letting the sheet regularly and gradually descend till it lies flat upon the surface of the solution. Practice will be required before the stripes or shades will be produced with certainty and regularity. We will next take a pattern with three veins.
No. 15.—blue or slate spanish.
This is performed in a similar manner to the one just described. First, throw on red, next yellow, thirdly Blue, and lastly the slate, or body-colour, which is composed of indigo, Chinese blue, and a portion of white. We now advance a step further and take up a pattern with four veins.
No. 16.—brown spanish.
This is a well-known pattern. Perhaps as much or more of it has been made than of any other, and it always will be a standing pattern. Proceed in the same manner as before, throwing on first, the red; then yellow; thirdly, blue; fourthly, black; and lastly, the brown, which should be composed of good burnt ochre, darkened with a little black.
No. 17.—double brown spanish.
This pattern has four colours for veins and two body-colours, the last or top colour being a dilution of the other with white. The veins are thrown on in the following order:—first, red; then black; next yellow, (some work the yellow before the black;) fourthly, green; then the brown, which must not be quite so powerful or put on quite so heavy as for brown Spanish, and on this sprinkle the light or top colour, which requires to be stronger in gall than the others.
