the glois or brightness appearing on any thing, particularly on manufactures of silk, wool, or stuff. It is likewise used to denote the composition or manner of giving that glois.

The lustre of silks is given them by washing in soap, then clear water, and dipping them in alum water cold. To give stuff a beautiful lustre: For every eight pounds of stuff allow a quarter of a pound of linseed; boil it half an hour, and then strain it through a cloth, and let it stand till it is turned almost to a jelly: afterwards put an ounce and a half of gum to dissolve 24 hours; then mix the liquor, and put the cloth into this mixture; take it out, dry it in the shade, and press it. If once doing is not sufficient, repeat the operation. Curriers give a lustre to black leather first with juice of barberries, then with gum-arabic, ale, vinegar, and Flanders glue, boiled together. For coloured leather, they use the white of an egg beaten in water. Moroccos have their lustre from juice of barberries, and lemon or orange. For hats, the lustre is frequently given with common water: sometimes a little black dye is added: the fame lustre serves for furs, except that for very black furs they sometimes prepare a lustre of galls, copperas, Roman alum, ox's marrow, and other ingredients.
