MISCELLANEOUS. 



hclf an hour dyes the color thoroughly 

 c:i the fibre. If you add sulphuric acid 

 to the same dye-bath, and turn the goods 

 in it, you can change the scarlet into a 

 bright orange. 



DYEING, on Silk.— Dye exactly like 

 the orange, but do not add any sulphuric 

 acid to the bath. 



DYE (Catechu), Brown.— Steep four 

 ounces catechu and half an ounce blue 

 vitriol about one hour in a brass or cop- 

 per kettle, with the amount of water 

 deemed necessary to work in easily. 

 Then put in the goods and steep, at a 

 scalding heat, from five to ten hours, stir- 

 ring often, and adding water from time to 

 time to make up for the loss in steam. 

 Lift out, cool rinse in clean water, and 

 dry. If the color is not dark enough, 

 make a bath, using half an ounce of 

 bichromate of potash in five or six gal- 

 lons of water, and steep the goods in it, 

 .at a scalding heat, one hour, stirring 

 •often. Lift out, cool, rinse, and dry. 

 This is sufficient for two pounds of 

 ■cotton. 



DYE (Chemic), Blue, to Make.— Chemic 

 for light blue and green, on silk, cotton, 

 • or woolen, and for cleaning and whiten- 

 ing cottons, is made by the following 

 process : 



Take one pound of oil of vitriol, 

 which pour upon one ounce of the best 

 ^Spanish flora indigo, well pounded and 

 •.sifted; add to this, after it has been well 

 sstirred, a small lump of common pearlash 

 .as big as a pea, or from that to the size 

 (•of two peas ; this will immediately raise 

 a great fermentation, and cause the in- 

 digo to dissolve in more minute and finer 

 particles than otherwise. As soon as 

 this fermentation ceases, put it into a 

 "bottle, tightly corked, and it may be used 

 the next day. If more than the quantity 

 of pearlash "be used, it will deaden and 

 sully the color. 



DYE (Chemic), Green. — This is made 

 the same as chemic blue, by adding one- 

 fourth more of oil of vitriol. If the 

 chemic is to be used for woolen, East 

 India indigo will answer the purpose even 

 better than Spanish indigo, and at a less 

 price; but the oil of vitriol is good for 

 both green and blue. 



DYE COLORS, to Discharge.— The 

 dyers generally put all colored silk 

 which are to be discharged into a copper, 



in which half a pound of white soap has 

 been dissolved. They are then to be 

 boiled off. The copper beginning to 

 be full of color, the silks are taken out 

 and rinsed in warm water. In the 

 interim, a fresh solution of soap is to be 

 added to the copper, and then proceed as 

 before, till all the color is discharged. 



DYE, Compound Colors. — Compound 

 colors are produced by mixing togethei 

 two simple ones ; or, which is the same 

 thing, by dyeing cloth first of the simple 

 color, and then by another. These colors 

 vary to affinity, according to the propor- 

 tion of the ingredients employed. From 

 blue, red, and yellow, red-olives and 

 greenish-grays are made. 



From blue, red, and brown, olives arc. 

 made, from the lightest to the darkes\ 

 shades ; and by giving a greater shade 

 of red, the slated and lavender-grays ar& 

 made. 



From blue, red, and black, grays of all 

 shades are made, such as sage, pigeon, 

 slate, and lead grays. The king's 01 

 prince's color is duller than usual ; this 

 mixture produces a variety of hues, ot 

 colors almost to infinity. 



From yellow, blue, and brown, are 

 made the goose-dung and olives of all 

 kinds. 



From brown, blue, and black, are pro- 

 duced brown-olives and their shades. 



From the red, yellow, and brown, are 

 derived the orange, gold-color, feuille- 

 mort, or faded leaf, dead carnations, cin- 

 namon, fawn, and tobacco, by using two 

 or three of the colors as required 



From yellow, red and black, browns of 

 every shade are made. 



From the blue and yellow, greens of all 

 shades. 



From red and blue, purples of all kinds 

 are formed. 



DYE, Crimson, a Shawl to. — Take 

 about a table-spoonful of cudbear ; put 

 it into a small pan, pour boiling water 

 upon it, stir and let it stand a few min- 

 utes, then put in your silk, and turn it 

 over a short time, and when the color is 

 full enough, take it out ; but if it should 

 require more violet or crimson, add a 

 tea-spoonful or two of purple archil to 

 some warm water, and dry it within 

 doors. To finish it, it must be mangled 

 or calendered, and may be pressed, if 

 such a convenience is at hand.
