into a proper tub, and the weld boiled again. While the boilings are going on, three tubs, being wine pipes cut in two, must be got ready, and made particularly clean, being also previously seasoned for the work. One is to receive the boiled weld with some cold water to regulate it to the heat which the hand will bear; the other is for water, and as much alum liquor as will colour it and make it taste strong; and the third is to contain clear water to wash the furniture off. Whatever yellow is in fashion (or indeed any fashionable colour,) has commonly a fashionable name. But if the dyer can, by his experience, proportion his drugs to the weakest, and from that to the strongest shade, let the name be what it may, after he has a set of patterns of his own dyeing, he will see, upon the first sight of any colour, how to set about it. In the present instance let the pattern be a moderately pale colour of yellow ; then put all the first boiling of the weld in the first tub, and cool down as above directed. Two or three persons should then work the pieces quick from end to end by the selvages; that they may be even, two may do this; one of whom must be an expeditious hand to work them and keep them even. When they have been edged over six or seven times, they are to be folded upon a board laid over the tub, and wrung as dry as possible by two persons. When they are all out, they are passed in the same manner through the tub of alum, and, after six or seven turns, they are to be taken out of the alum liquor, wrung as before, and then washed off. By this time the second weld liquor will be boiled ; some of the first must be thrown away, and the second weld liquor added in its place. The goods are then passed through as before, and wrung out; the alum liquor being strengthened, they are passed through it, wrung out as before, and then washed off: the water in the wash tub having been changed. In some instances verdegris is used instead of alum ; and in other cases it is used in addition to the alum. For some shades old fustic is used instead of weld, and sulphate of copper instead of verdegris. The alum solution, and the sulphate of copper, and the verdegris, or acetate of copper, should be always ready. It is necessary to have a tub for each, in size proportioned to the work to be done; but larger for the alum than for the other two. Sulphate of iron is also used in some dark grays, browns, slates, and in all blacks; this will require a tub as large or larger than that for alum. When the yellows are dyed and wrung as dry as possible, they should be taken into a close room or stove to dry, particularly in London, because of the smoke, especially in winter. A German, or other stove, should be placed in the room, the size of which, as well as the number of the stoves, must be regulated by the quantity of work. When the goods are dry they must be sent to the calenderers, if directed to be calendered; but the general and better way is to stiffen them with starch after they are dyed, and before they are dry; and when dry they should be sent to the glaziers, instead of the calenderers, except when both branches are carried on by the same person. When furniture, originally yellow, has become faded, it may be re-dyed thus: in this case it should be dyed rather of a fuller shade than the original. A large flat tub, such as described above, is to be filled three parts full of water, to which sufficient sulphuric acid must be added to make it taste strongly sour. After being well stirred, the pieces are to be put in,
