 wanted. 



No. 79. Any shade of pale red for machine is made by reducing the quantities of

The white reserve for this variety of neutrals is either of the mild pastes. 



No. 80. Resist Brown. 2 gallons water, 24 Ibs. catechu, 6 Ibs. sal-ammoniac, 1 

 gallon acetic acid; boil 15 minutes, and add 7i gallons gum-solution, 5 quarts nitraSo 

 of copper at 100 T. 



Process. Tho colours after printing are aged 3 days, then dipped light blue in 

 the following blue vat : 



(No. 4.) Neutral vat. 1,000 gallons water, 120 Ibs. indigo, 135 Ibs. copperas, 150 

 Ibs. lime ; rake up for two days, and let settle. 



A frame with rollers top and bottom is lowered into this, and the pieces are run 

 through ; after leaving the vat, they are made to travel over rollers in the air for a 

 sufficient distance to turn them blue ; then into a pit of water, from that into a beck 

 with cow-dung and water, at 160 F., where they run 15 minutes, then washed and 

 dyed madder or garancin, &c. &c. 



In the second variety of neutrals, the white is required to resist both mordants and 

 blue, and is made thus : 



No. 81. Neutral White for Blocks. 7 quarts lime juice at 30 T., 1 quart water, 

 4 Ibs. sulphate of copper, 24 Ibs. pipe-clay, 3^ quarts lime juice at 30 T., previously 

 thickened with gum-Senegal. 



No. 82. Neutral White for Machine. 1 gallon lime juice at 42 T., 2 Ibs. sulphate 

 of copper, 32 oz, measure nitrate of copper at 100 T., thickened with 1-J- Ib. starch. 



The black is the ordinary madder or garancin black, Nos. 4 and 5 process. 



The neutral white is first printed either by block or machine ; if the latter, it cannot 

 be in a pattern which should register accurately with the subsequent colours, as it 

 must be dried perfectly before the other colours are printed, to avoid obtaining 

 irregular shapes ; the above reserve colours are then printed over the neutral white. 

 Mild paste Nos. 69, 70 may also bo printed along with the other colours, to reserve a 

 white under the blue only. The subsequent process is the same as for the first 

 variety. 



After dyeing madder and garancin, and clearing with soap, &c., steam or spirit 

 colours are generally blocked in. Parts of the yellow being made to fall over the blue 

 form green. 



Sixth Style: China Blues. 



China blues, so called from the shade of blue resembling that on porcelain. In this 

 style indigo is printed on, and made to penetrate and fix in the cloth by the subse- 

 quent process. 



The colour is made thus : 



No. 83. Standard China Blue. In an indigo mill are put 45 Ibs. indigo, 9 gallons 

 iron liquor at 24 T., and 18 Ibs. copperas, the whole ground till quite fine ; then add 

 7 gallons gum-Senegal solution at 6 Ibs. per gallon ; grind an hour longer, take out 

 and wash the mill with 6 quarts hot water, and add to the above.
