XXI L Process for Di/eing Nankeen Colour. By Mr. RiCHAro 



BREWtU.* 



-i\jLix as much sheep's dung in clear water as will make \\ 

 appear of the colour of grass, and dissolve in clear wa'.er 

 one pound of best white soap for every ten pounds of 

 cotton-yarn, or in that proportiou for a greater of lesser 

 quantity. 



Observe : — The tubs, boards, and poles, that are used in 

 the following operations must Ue made of deal ; the boiling- 

 pan of either iron or copjijci'. 



First Operation. 



Pour the soap liquor prepared as above into the boilins- 

 p'an ; strain the dung liquor through a sieve ; add as nmch 

 thereof to the soap liquor in the pan as will be sufficient to 

 boil the yarn, intended to be dyed, for five hours. Whea 

 the liquors are well mixed in the pan, enter the yarn, light 

 the fire under the pan, and bring the liquor to boil in about; 

 two hours, observing to increase the heat regularly during 

 that period. Continue it boiling for three hours, then take 

 4he yarn out of the pan, wash it, wring it, and hang it iu 

 4 shed on poles to dry. When dry, take it into a stove or 

 other room where there is a fire ; let it hang there until it 

 be thoroughly dry, 



N. B. Tbe cotton yarn, vthen in the shed, should not 

 be exposed either to the rain or sun : if it is, it will be un- 

 equally coloured when dyed. 



Second Operation. 



In this operation use only one half of the soap that was 

 used in the last, and as much dung liquor (strained as be- 

 fore directed) as will be sufficient to cover the cotton yarn^ 

 when in the pan, about two inches. When these liquor^ 

 are well mixed in the pan, enter the yarn, light the fire^ 

 and bring the liijuor to boil in about one hour ; then take 

 the yarn out, wring it without wasiiing, and hang it to dry 

 as in the fornicr operation.
