During tliis second process vvoad ashes* are to lie dissolved in a ket- 

 tle into which you have poured some of the liquor of ihe second co- 

 loring, boiling hot; stir the liquor and woad ashes well, and then let it 

 settle: pour sonie of the clear part of the solution into the yellow li- 

 qiior, after having first taken out the silk; stir the whole of it well, 

 Bteep the silk in it again, and work it well therein during fifteen mi- 

 nutes. At the expiration of this time, or sooner, as you may deem it 

 necessary, take out a small quanlitj' of the silk, wring it, and examine 

 whether it has retained the required color; should this not be the case, 

 a small quantity of the solution of woad ashes must be added to the li- 

 quor, the silk steeped in it again, and well worked in the same, until 

 the required color be obtained. 



^oTE.-^Should it be desired to heighten this color to a deep colored gold tint, 

 add to the solution of woad ashes a quantity of annotto, in proportion to the degree 

 of color desired. 



The dying- of light colored yellows is generally attended with many difficulties, as 

 they vvili o^'wn be subject to changes in drying; and sometimes they will turn to a 

 darker tint than tiiey had wliile the silk Avas yet in a wet state; thi« is caused, prin- 

 cipally, by too strong a dressing in alum. It is, therefore, best to give them a weak 

 dressing in alum liy themselves, or separate from tliose silks whicli are intended for 

 othei colors; and this may then be regulated, according to the degree of the color 

 fiesired.

 and throw away the solution of alum as useless. Put again ten buck- 

 ets of fresh water in the kettle, add eight pounds of safflower, and the 

 quarter of a pound of alum; boil for half an hour, run the decoction 

 through a sieve into a vat, steep the silk in the liquor, work it avcU 

 therein a quarter of an hour, wring and dry it, fix it on the wringing

* The woad ashes are chosen for this purpose, on account of possessingthe qualt 

 ty, better than any other, of dissolving the coloring matter of tlie Lady's or St- Mary's 

 Tliistle, and of incorporating it with the silk.
