The silk being alumed as usual rather strongly, is washed off and divided on the sticks into small hanks of about four or five ounces, that it may be equally and easily managed in the working, from the yellow to green, in the blueing from the blue vat. Weld is then boiled as stated in the article concerning _yellow_; when boiled, a liquor of it is prepared strong enough to give a lemon ground; the silk is then turned with all the expedition, care, and caution possible, that it may be even. When it appears full enough, some of the threads are to be separated and dipped in the vat, to determine this. If not full enough, more of the weld liquor must be added to the dye bath, and the silk returned and tried again, and so on; when the colour is right, the silk is washed off and beetled. It is then wrung and formed into hanks, and dipped skein by skein in the blue vat, the same as the blue and the purple should be; it must be wrung with equal care and dispatch. This green is a kind of _sea-green_, of which there are upwards of twenty shades. The lighter shades, when taken out of the vat, are not washed but the silk must be worked in the hands by clapping it between them, and then be carefully opened and aired. A few threads are then washed, or rinsed; if the colour be right the whole is washed. For the dark shades, when the weld is exhausted a little logwood is added to the liquor; in some cases, old fustic, in some annatto. For _very dark-wing_ or _bottle-green_ shades, a little sulphate of iron is required. OLIVES. Proceed in aluming, &c. the same as for other colours; the weld liquor being stronger, some logwood must be added. When the weld and logwood are exhausted a very small quantity of each must be added, which green the liquor, when the silk being passed through, a _greenish olive_ is produced. A _reddish olive_ requires fustic, instead of logwood and pearl-ash, both of these being omitted. Fustic gives a colour commonly called _drab-olive_ upon cloth, because generally made to match with olive, this is commonly redder than the preceding. _On dyeing silk_ GREY. All the _greys_, namely, _nut-greys_, _thorn-greys_, _black_ and _iron-greys_, and others of the same hue, black-grey excepted, are produced without aluming. The silk being washed from the soap and drained on the peg, a liquor is made of fustic, archil, logwood and sulphate of iron: fustic gives the ground, archil the red, logwood darkens, and the sulphate of iron softens all these colours, turns them grey, and, at the same time, serves instead of alum as a mordant. As there is an infinite variety of greys, without any positive names, produced by the same methods, it would be endless to enter into details, which would prolong this treatise to little purpose. For _reddish-grey_ the archil should predominate; for those more grey, the logwood; and for those rather greenish, the fustic.
