To prepare the silver dye.
Allow half a pound of alum for every fifteen yards of stuff, and three quarters of fenugreek, let them boil for half an hour, then add one pound of pot-ashes, and half a pound of Brasil, in which boil the stuffs for a quarter of an hour.

Another.
To dye a pair of stockings; take six galls, and an equal weight of gum Arabick, and the like weight of alum, with a small quantity of brown Brazil wood; boil these in rain-water, then cool the stockings out or the liquor three times.

To dye stuff a lasting silver dye.
First tinge the stuffs of a light grey in the woad, then rinse it clean, and dry it; but you must take notice, that the whiter the stuff is before it is dyed, the brighter will be the lustre.

To black or deepen it; take an ounce and half of powdered galls, four ounces and a half of vitriol, and half an ounce of sal-armoniac, two ounces of madder, and a quarter of an ounce of salt-petre; and prepare them as the ash-colour above-mentioned. But if you would have it incline more to the red, add two ounces of boil'd Brasil, two ounces of sharp lye, a quarter of an ounce of calcin'd alum, and a drachm of calcin'd tartar, and it will appear very beautiful.
