The materials of which the glass is composed, as far as can be ascertained, and they seem to make no secret of it, appear to be the same as those in use in England; they say, they derive their perfection from their mode of mixing and burning the material. Thus the principal component parts are:--Sand; chalk; potash; brimstone; arsenic, mixed with various colors, regulated by the principal:--Uran oxide; cobalt oxide; coppré oxide; nickel oxide; chrom oxide; minium; tin oxide. The gold used in ornamenting the glass is from the purest ducats, dissolved in strong acid (artz wasser), the oil with which the colors are mixed is of turpentine (harz öhl). Nothing is done in most of the blowing fabriques but mixing the material, and coloring; and for cutting, polishing, &c., from three to six wheels are used--all the finishing goes on in the little cottages by which the furnace is surrounded, and with which the valleys and sides of the hills are studded; here you find, within the contracted chambers of these small block-houses, if on the ground-flat, standing on an earthen[2] floor like our Highland cottages, an artist of the first ability, tracing the exquisite scrolls and flowers which we see in these beautiful works of art; and which are performed by men bearing all the appearance of simple cotters; but whose hand sweeps free and careless over the glass with the confidence and ease of an experienced artist; seldom being provided with more than two very ordinary looking brushes, a small one and another a size larger, and working frequently without any pattern, or indicating lines upon the glass they are painting; but perfect from habitude, the scrolls, and wreaths, and flowers, come out with the same facility as one traces a name upon the dewy pane of a window. Often the whole family are brought up from childhood in painting and in drawing on glass, and thus producing a race of hereditary artists; boys from thirteen and upwards are employed in the most delicate works in this genre of art. Each cottage where the painting and gilding go on, is provided with a small oven, into which the glass is put to bake in the colors, where it is kept for a day and allowed to cool down; the white figures and flowers, when they go into the oven, are of a dark chrome color, but come out pure white, as will be observed on examining any glass on which flowers of this color are painted; the gold, also, when laid on, is of a dead brown, and when burnt in, is polished, generally by women of the family. The gold in many instances is left unpolished, and only the stalks and fibres are burnished, which give an excellent effect. It is most interesting to go from one cottage to another; in one you are amazed by the exquisite paintings in gold, silver, and colors; in another, the cutting out all those beautiful leaf-work, lily, bell-flower, octagon, and star-shaped vases, which is done, not only by men, but by their children, girls and boys. In one cottage, I was
